[...]Hull (Saltend), UK HUBER Technology recently supplied, installed and commissioned coarse and fine inlet screens, launder systems and screenings handling plant for both sets of screens at one of Yorkshire Water’s largest wastewater treatment, Hull (Saltend). The new elevated inlet works that houses the HUBER equipment is designed to treat the flow to full treatment of 2140 l/s and a population equivalent approaching 450,000. In addition to the construction of a new inlet works, HUBER were successful in securing the subcontract to supply 2 No. Ro3 sludge screens as part of the upgrade of the sludge treatment facility. Coarse screening plant For this section of the works, HUBER designed, manufactured, installed and commissioned 3 No. 75° RakeMax ® Multi-Rake Bar screens with 25 mm bar spacings. These screens operate on a duty, assist, and standby basis and were selected and designed to ensure that the velocity through the bars does not exceed 1.2 m/s whilst maintaining good channel velocities at peak flows. Coarse screens screenings handling system Each RakeMax® screen discharges into a stainless steel common launder designed and installed by HUBER. Because of the elevated position of the screens and common launder, a drop pipe was required to deliver the launder water and screenings to 3 No. twin-screw WAP® SL 12v wash presses. Each of the wash presses is designed to process 12 m3/hour of wet screenings at a fixed speed, which can then be increased to 18.5 m3/hour via frequency inverters if it becomes necessary. The site P.E. and appropriate peak factor meant that a predicted peak volume of 26.42 m3/hour might arrive at the works so it was necessary to ‘sequence’ the operation of the WAP® SL wash presses to facilitate duty, assist and standby operation. The reception hoppers of the WAP ® SL wash presses are fitted with vortex impellors that create significant agitation of the screenings and launder water within them. This method of screenings washing means that a permanent pressurised washwater system is not required. By knowing the volume of the reception hoppers and the amount of launder water present, we calculated the level within them that when reached initiates the closing of the knife gate valve within the launder. This means that the next WAP ® SL in the sequence starts to fill whilst the ‘duty’ unit processes the screenings and launder water. However, we expect that this sequencing will only be required in exceptional circumstances. All three WAP ® SL wash presses discharge washed and cleaned screenings into specially designed compactor skips to optimise all the space within them and reduce the number of overall skip movements. Filtrate from the WAP ® SL Wash Presses is discharged to local drains. Fine screening plant For this section of the works HUBER designed, manufactured, installed and commissioned 4 No. 45° HUBER Belt Screen EscaMax ® 6 mm perforated plate screens. These screens operate on a duty, assist, assist, standby basis and were selected and designed to ensure that the velocity through the perforations does not exceed 1.2 m/s whilst maintaining good channel velocity at peak flows. One of the major challenges was around the angle at which the screens should be installed. However, we were able to convince the client and the contractor that installing the screens at 45° would provide them with far more benefits than if installed at the standard angle of 60°. In our opinion, it would have been unwise to compromise on the screens being able to remove the predicted peak screenings loading of 26.42 m3/hour, and installing them at 45°was absolutely necessary to achieve this. Both the client and main contractor showed a real level of maturity during discussions about this and the hydraulics relative to both sets of screens and the loadings associated with the screenings handling plant. Fine screens screenings handling system Each EscaMax ® screen discharges into a stainless steel common launder designed and installed by HUBER. The launder and each of the WAP ® SL 12v wash presses are designed the same as the plant serving the RakeMax ® coarse screens and operates in the same manner. Sludge treatment facility upgrade HUBER also supplied, installed and commissioned 2 No. of the well-established Ro3 sludge acceptance screens on this project. The ROTAMAT® Ro3 sludge acceptance plants are designed and built as a packaged item of plant, but at the heart of every solution is the ROTAMAT® Ro1 fine screen. Manufactured completely in stainless steel, it provides high removal efficiency, low head loss as well as longevity of service. The ROTAMAT® Ro1 fine screen, with its rugged construction is cleaned by fully engaged rake tines passing through the bars of the screen that capture the solids. The integrated screenings press transports the screenings out of the tank, dewaters, reduces volume and finally discharges the treated screenings into a skip. In addition, the screenings are washed and the press water is returned downstream of the screen. As a result, the screenings are clean and can be disposed of safely. The entire screening process takes place in a closed system avoiding odour annoyance, but the machines can be connected to odour control systems when required. The efficiency and rugged construction is able to cope with throughputs up to 230 m3/h. The ROTAMAT® Ro3 sludge acceptance plant is the best-selling machine of its type in the UK. Compact construction, together with intelligent technology ensure reliable and continuous operation day after day, year after year. Dale Foster - Area Manager for HUBER Technology: “Prior to receiving the contract from the main contractor there were many hurdles to jump. Some of these were around challenges to the then current Yorkshire Water asset standards. As anyone who has had to do this will attest, this is never the easiest or quickest thing to do. However, once alternatives that deviated from current standards were appraised, having been backed up by compelling evidence, the decision relayed by the contractor via the client was swift, clear and decisive. As stated previously, the client and MMB, the main contractor, should be congratulated for the maturity shown throughout the process of delivering this project. We are confident that the equipment supplied will provide the end user with a significantly improved and reliable inlet works that will benefit the downstream processes and the Ro3 sludge screens will work tirelessly, but reliably in a very harsh environment. This is a flagship site for Yorkshire Water and we are proud of our contribution towards the significant upgrade of the works”[...]

[...]Cardston, UK The City of Cardston’s Wastewater Treatment Plant is aging yet still performs well in providing the services that its population needs. The close knit community has had some issues with odors from the WWTP but it is a trade-off for free fertilizer the plant provides to local barley farmers. One of the ways that Cardston has maintained WWTP performance is by employing leading technology within the wastewater treatment process. What the citizens of Cardston didn’t know was that when the WWTP chose to install HUBER’s Screw Press Q-PRESS®, it would not only improve performance, but it would also change the plant’s role in the community. Water and Wastewater Utilities Foreman, Bart Atwood, had researched liquid separation solutions and formulated these goals for implementing new press technology: Upgrade to current technology Improve the quality of end-products (water and biosolids) Reduce odors that caused community complaints Reduce costs associated with separation/pressing Increase efficiency for operators Challenge: Atwood’s existing belt press represents the old approach to liquid separation. There are new approaches to this process that include the screw press and centrifuge. Atwood’s research led him to the conclusion that the screw press type of solution would best help him meet his goals. After visiting several installations of HUBER’s Q-PRESS® – and observing its simple yet effective operation firsthand – Atwood made the decision to bring the HUBER technology into the Cardston plant. Solution: Atwood and his team immediately noticed the small footprint of the Q-Press. The new screw press took up less than half the space that the old belt press had occupied. This was striking for the operations team but not as striking as the fraction of time they needed to spend managing the screw press. While the belt press needed constant attention, the screw press required nothing past being turned on and off. It seemed to Atwood that he had gotten an additional team member because one of his operators was freed from the duty of tending the belt press. There was another notable difference with the new technology: No odor. “This is as odorless as this type of process could possibly be. Unlike with the belt press, I wouldn’t be afraid to stick my nose down and sniff the water or the biosolids going through our screw press,” says Atwood of his odor-free operation. The screw press more effectively separates the water from the biosolids – practically creating a dry solid end-product. The resulting water is cleaner than the water that comes into the headworks and produces no gaseous odor as it is fed back into the channel as the water does in the belt press process. This was critical for Atwood in fulfilling his goal of improving the plant’s impact on the community. The premiere piece of equipment in the plant Q-PRESS® performs so efficiently that is has become the star of the show for Atwood’s team. According to Atwood, “The screw press also demands less from our transportation resources. There is less bio solid to take to haul away. Since we store our bi solids for 2 years prior to using them for land application as fertilizer, the screw press also helps us reduce our costs to store our biosolids.” The cost savings alone could earn it notoriety. After all, the savings impact man hours, transportation, storages and resources. It saves Atwood’s team time because it requires no operational management. It saves in trucking costs, spreading costs and storage costs because the biosolids are dryer and easier to handle. Prior to the Q-PRESS®, Atwood’s trucks ran two times a day. After implementing Q-PRESS® this schedule was reduced to two times per week. It helps Cardston conserve water and electricity by requiring less of each to operate. The automation bonus The automation built into the Q-PRESS® gives Atwood’s team freedom. They are able to control shutdown and startup by just logging in. So issues that would have previously brought them into the plant from home during the night can be stopped remotely and addressed by the morning shift without impact to performance, maintenance or daily flow. Obvious benefits keep aging plant competitive Cardston WWTP has realized the powerful benefits of the Q-PRESS®. Although Cardston WWTP is older (30 years of operation) than some of the treatment plants of neighboring cities, it maintains its competitiveness – even in sensitive areas such as compliance. Cardston WWTP’s chemical compliance test results have improved since installing the Q-PRESS®. Their compliance was never jeopardized with previous technology, but, as Atwood notes, it is always good to have a wider margin in that area. HUBER Screw Press Q-PRESS® is a solution that performs liquid/solid separation that: Requires less space Operates quietly Is really odorless Conserves water and power Is simple to maintain, operate Industry insight enables HUBER to gear its solutions to the demands and concerns of the wastewater treatment plant environment. For example, consider corrosion and simplicity. Corrosion is a big concern within an environment that is wrought with it. HUBER manufactures everything from stainless steel so that corrosion is never a factor. Performance in a WWTP plummets when any component isn’t simple for users to manage. HUBER designs simplicity into every aspect of its solutions. Becoming a good community citizen Of utmost importance to Atwood of implementing HUBER’s Q-PRESS® is how it has helped the plant become a better citizen of the Cardston community. While the conservation benefits in both water and energy have caught the attention of the neighbors, the most shocking change has been in the absence of odor surrounding the plant and its fertilizer. No longer do residents complain about foul smells emitted from the plant nor do they hold their noses when a plant truck makes a fertilizer delivery to a local farmer. Four performance factors help Cardston WWTP become a better citizen: Water usage has dropped from 150 cubic meters a day to 100 cubic meters a week. Electricity demands are much less than with the previous belt press system. Fewer truck routes to deliver biosolids reduce fuel consumption. Cleaner processing eliminates odors that are offensive to neighbors Durability, reliability and support Q-PRESS® is rock solid. Its stainless steel design keeps the screw press in mint condition. Its performance gives Atwood and his team total confidence that the Q-PRESS® will just work. They can depend on it. HUBER’s customer support is also rock solid. The Cardston team can depend on immediate responses at the rare points that they actually need answers or help. HUBER’s support experts are available with assistance. When deeper expertise is required, HUBER connects the best resources with the customer. HUBER’s experience with municipalities and with wastewater processes is extensive as is its knowledge of the technologies it provides. This industry-technology insight allows HUBER to work with organizations to ensure that systems are geared to perfectly match up to immediate tactical challenges and long-term strategic goals.[...]

[...]Westnewton , UK Westnewton WwTW is located close to the Solway Coast and treats a population equivalent of 275. Flows arrive at a terminal pumping station off site and is pumped up to the WwTW for treatment. After treatment flow exits the works into Westnewton Beck. HUBER Technology supplied, installed and commissioned a duty/standby 3 mm 2D inlet screening package also incorporating a handraked bypass channel with a 12 mm bar screen fitted and local control stations to the Contract Delivery Partner (CDP) C2V+. This equipment is located upstream of a Nereda® process specifically designed for smaller works. (Royal HaskoningDHV has developed small (Package) and medium scale (Mini) solutions for 200-2,000 PE and 2,000-5,000 PE respectively, with support from UU and C2V+ United Utilities’ construction design partner.) This scheme sought to use as much equipment delivered in the DfMA (built off sire) format as possible and from HUBER Technology’s perspective, this opened up the opportunity to develop this further with Advance plus and C2V+, the CDP’s for United Utilities. As a result of this together we developed a truly collaborative way of working to reduce costs and improve efficiencies to deliver United Utilities (UU) AMP7 programme. The approach focused on partnership, collaboration, trust that compliment UU AMP7 requirements to outperform against their Company Business Plan (CBP) and benefit all parties. The solution was initially developed on Advance-plus projects at Southwaite and Greystoke WwTW. It was subsequently adopted by C2V+ at Gawsworth WwTW with several other projects in the pipeline. The highlights of this approach are: A £30K (35%) saving in capital cost against a bespoke solution at £80k. An annual ongoing saving of £8,600pa against historical, conventional installations. Utilisation of standard steel products instead of bespoke civil channels – saved £11k – 12% i.e.: Standard off-the shelf designs. Simplified asset standards. Reduced civil construction. DfMA off-site build saved £15k – 18% i.e.: 5 weeks site time saved. Safer assembly. Lower carbon solutions >70% reduction. Less waste. Factory based quality assurance (100%). Less travel and fuel costs. Interface management and out-turn cost certainty. Offsite testing and dry commissioning. Programme and design work saved £4.1k – 5% - Common product specifications and configuration, reduced design turbulence – less iteration i.e.: Estimating – standard estimating blocks. Procurement – Avoidance of multiple quotes, proforma subcontract (proforma agreements). Planning & Scheduling – standard timeframes for procurement lead time, installation and commissioning. Safety - Template HAZOP and Access, Lifting and Maintenance (ALM) agreements, reduced travel and meetings (Do it once). Standard commissioning protocols, maintenance and spares familiarity. Agreed OPEX costings for Investment Appraisal Analysis and WLC reporting. Ongoing savings through. Lower operating costs – defined by the historical data findings. Operator familiarity. Ongoing 35% capital savings on future schemes. £8,600pa – maintenance and operating costs. This piece of work was shortlisted for the 2021 Water Industry Awards for the Alliancing and Partnership Initiative. Dale Foster - Area Manager for HUBER Technology: “It has been both a pleasure and hard work over a long period of time to arrive at standard inlet screening package solutions for deployment on United Utilities projects targeting small inlet works. The potential for efficiency savings that this approach offers throughout the AMP period and beyond is there for all to see. With the resulting improvement in quality, cost and time together with reduced health and safety risk and carbon emissions, it’s quite a result. It looks and sounds simple when seeing the results in writing but a lot of people throughout all the organisations mentioned put in a deal of hard work and diligence. Hopefully, as with other water companies, the potential this approach offers for other work streams can also be realised. The kit installed on this site will no doubt provide reliable and trouble free service for many years to come. Many of its Ro9 screen predecessors that are installed throughout the United Utilities region are well into 20+ years of service and prove very undemanding from an OPEX perspective. I am certain this will be the case at Westnewton WwTW.”[...]

[...]Winchcombe STW, UK HUBER Technology recently completed a project for Severn Trent Water at Winchcombe STW, north of Cheltenham. Following the successful installation of a similar project at Stratford Milcote HUBER Technology were engaged by CiM6 on the project in 2017 with the project being installed in 2019 and commissioned in early 2020. Project Profile This project was part of the upgrade to the Winchcombe STW to provide sludge thickening to reduce operational costs of tankering thin sludge from site HUBER Technology Supplied 1 x HUBER Disc Thickener S-DISC Sludge Thickener mounted onto a skid complete with Severn Trent Water specification control panel and polymer dosing pump. Objective The primary objective was to reduce tankering costs on site by thickening the sludge from activated sludge plant on site. It was also an opportunity to learn from the project at Stratford Milcote and utilise the proven offsite build of a skid mounted solution. Solution The solution was to install a fully off site built skid mounted sludge thickener into a new kiosk. The skid comprised the S-DISC 1 sludge thickener, flocculation reactor, polyrex 1.0 poly dosing unit, Severn Trent specification control panel and discharge pump The skid had an overall footprint of 5.5m x 2.4m The sludge was wholly made up of SAS from the on site activated sludge with a throughput of 7.962m 3 /hr required at 0.4 - 1% D.S. A dry solids content of >6% was required for the outlet. Based on feedback from the Stratford Milcote project this type of solution typically saves 40% in capital cost as well as reducing their operational costs by over 20%. Product Profile A slightly inclined, slowly rotating filter disc covered with a filter cloth separates flocculated sludge from filtrate. A baffle plate distributes the inflow evenly across the entire filter radius. Sludge liquor collects on the bottom section of the filter disc so that a low hydrostatic pressure develops enhancing sludge liquor drain-off. Flexibly supported ploughs divide and move the sludge layer on the disc and open up furrows so that water can easily drain through the filter cloth, thus enhancing the filtration effect. At the sludge discharge outlet, a scraper pushes the thickened sludge from the disc. The filter cloth is cleaned by a spray bar so that the solids are washed back into the sludge to ensure the filtrate water is clear Compact, enclosed design Efficient, reliable and simple to operate Low operation and maintenance costs High throughput capacity > 40m³/h Multiple awards “Following the success of the first skid mounted unit at Stratford Milcote it was great to build on the experience of that solution to deliver a similar solution for Winchcombe STW, Severn Trent Water should hopefully see the huge benefit of this technology in reducing operating costs on site.” Richard Willis - Area Manager[...]

[...]Basildon, UK Working with I.O.S., a delivery arm of Anglian Water, together we developed a solution utilising HUBER Rotary Screw Thickeners S-DRUM and investigated how these well proven sludge thickeners might replace existing centrifuges. Background At their water recycling centre at Basildon WRC HpH technology (heating, pasteurisation & hydrolysis) has been operational for a number of years. The first step in the process uses hot water and steam to heat the sludge, typically this is recovered from the combined heat and power (CHP) engines that generate electricity from the biogas. The second step is pasteurisation, after which the sludge goes through a hydrolysis and acidification process, which pre-conditions it for efficient biogas conversion in the anaerobic digester. HUBER Technology were approached in 2020 to investigate how the well proven S-DRUM sludge thickeners might replace the existing Centrifuges to provide an average output of 8% DS, which is the ideal feed for the HpH process. Although the Centrifuges had provided a good service the cake output was often well above 8% DS. Before committing to scheme delivery, Anglian Water needed to gain confidence around the use of the S-DRUM thickeners, so a visit was arranged to see a very similar S-DRUM to those that would be required to meet the throughput and output requirements for this project. Scope of the project Working with I.O.S., a delivery arm of Anglian Water, together we developed a solution utilising duty/standby S-DRUM 4L sludge thickeners. Prior to the new equipment being ordered a design contract was awarded, which allowed all parties to see and understand exactly what the finished installation would look like. Following a design review a subcontract was awarded and work began to deliver the agreed solution. Due to having to maintain sludge thickening throughout the duration of the project it was necessary to phase the installation of the new S-DRUM thickeners. With supervision from Huber engineers I.O.S. carried out the work. The trickiest part of the project was integrating the controls for the S-DRUM thickeners with existing SCADA etc. However, with excellent teamwork this obstacle was overcome. Sludge thickening process parameters Sludge type Raw indigenous & imports Maximum dry solids content of incoming sludge 3.5 % Average outlet sludge concentration 8.0 % Maximum throughput required 45 m³/hour at maximum DS content Operating periods Up to 24 hours per day 7 days per week Mode of thickener operation Duty/standby Minimum solids recovery 95% HUBER Technology scope The design, manufacture, supply, delivery, the supervision of the phased mechanical installation, of: 2 x (duty/standby) HUBER S-DRUM 4L sludge thickeners c/w flocculation reactors. 2 x sets of polymer mixing valves and injection rings. 2 x Anglian Water compliant control panels. Commissioning and training of O&M staff. Unlike other drum thickeners that are predominantly installed horizontally, the S-DRUM is installed at an inclined angle. This has several advantages, the main one being there is no requirement to elevate them on support platforms to enable thickened sludge pumps to be located under the sludge discharge point. As can be seen above, some deem it necessary to erect permanent access platforms, however, this is on a significantly smaller scale when compared to what is required for conventional, horizontally mounted drum thickeners that also require kit specific concrete plinths onto which the thickeners are fixed – See below. This can significantly reduce the cost and the time taken to complete the installation of the overall solution as well as reducing the overall carbon footprint. Other advantages of the S-DRUM thickeners include: 20% reduction in operating costs versus GBT’s. 50% reduction in maintenance costs. Low energy requirements. Lower volume and pressure washwater demand. Less susceptible to ragging. Slow rotation/operation results in significantly less wear. Robust stainless steel wedge wire ‘screen’ built to last the asset life of the equipment. Dale Foster, HUBER Technology’s Area Manager commented: “ It was great to secure the first contract to supply our S-DRUM sludge thickeners within the Anglian Water area for this project. It is our expectation that once the kit has operated well for a long period of time sufficient interest will be generated for others to consider this technology for their sites. There are already interested parties. Word of mouth is why we have almost 100 S-DRUM installations in the UK and Ireland and 1,000’s globally .“ For more information please contact Rachael Harvey on 01249 765052 or email Rachael.Harvey@huber.co.uk .[...]

[...]The HUBER Screw Press Q-PRESS® 280 trial equipment has been busy over the last few months. Although it has been much harder and taken longer to organise than usual, we at HUBER Technology consider ourselves very fortunate to have been able to conduct business like this during the COVID pandemic. Trial 1 The first trial was at a site in the North East of England. The site has a Population Equivalent of 61,469 and a full flow to treatment of 463 l/s and which presently uses a Gravity Belt Thickener (GBT) to mechanically thicken the Surplus Activated Sludge (SAS) produced on site, which is then mixed in 2 storage tanks with the manually decanted indigenous primary sludge. Due to varying transfer volumes and times, the ratio of SAS to Primary in the sludge tanks can fluctuate significantly. Results summary Average Incoming DS 3.97% Average Cake DS 28.48% Trial 2 This was at a WwTW site that treats effluent from a Population Equivalent of 19,615 with a dry weather flow of 202 l/s and full flow to treatment of 505 l/s. Primary industries in the catchment are food manufacturers. The treatment on site produces roughly 320 m3/d of primary sludge from the Kaldnes moving bed bio-film process, which uses aeration and floating plastic media, and around 195 m3/d of Surplus Activated Sludge (SAS). The Kaldnes sludge was considered a “tricky” sludge to subsequently process. Results summary Average Incoming DS 3.92% Cake DS using enhanced mixing 23% These results demonstrate that the Q-Press® provides a viable alternative to centrifuges with the following benefits 80% power reduction compared to centrifuge 30% reduction in poly compared to belt presses 6 fold reduction in maintenance compared to centrifuge Reliable single moving part slow rotation Reduced operator interventions Filtrate drains by gravity Removable outer case for easy maintenance For full details on the trials and more performance results please contact Rachael Harvey at Rachael.harvey@huber.co.uk[...]

[...]Berching, Germany How it all began... In the 1950s and 1960s, manhole covers in "painted steel" and "galvanised steel" were proven products of the HUBER company and the covers were mainly manufactured for water pipeline construction. At the beginning of the 1970s, the brothers Hans and Karl-Josef Huber, the company owners at the time, recognised the desire and need of many customers for a low-maintenance manhole cover that did not require maintenance work such as regular painting of the surface. The idea of using stainless steel for this purpose was born and was implemented on a trial basis. At that time, stainless steel was very expensive and difficult to obtain, and delivery times were extremely long. The first covers were always produced according to the customer's wishes and specifications, using the experience gained over many years in the production of steel covers. Water suppliers from the Nuremberg area and large Bavarian long-distance water associations were the first customers for HUBER stainless steel manhole covers. Most of these covers are still in use today and, after 50 years, impressively demonstrate the long service life of the HUBER manhole cover - a role model in terms of sustainability! Since then, the use of stainless steel for manhole covers has become more and more widespread and, thanks to HUBER's pioneering work, has established itself in the market. In 1990, HUBER completely stopped the production of steel manhole covers and steel products and dedicated itself 100% to stainless steel. HUBER stainless steel manhole covers have become the norm Nowadays, tenders requiring a material other than stainless steel for manhole covers are the great exception, i.e. in the last 50 years the ratio has been exactly reversed. From these early beginnings, a wide range of different HUBER manhole cover designs have developed over the last five decades, always in close contact and cooperation with our customers. Especially the feedback from our customers we receive in discussions at trade fairs, through telephone calls or during field service visits, was then and still is extremely valuable. The practical application and regular use of the covers by our customers provide important approaches to continuously improve our products and thus maintain the HUBER quality they have come to expect. Feedback from the market, e.g. requesting a back-friendly opening of the heavy covers, prompted us to equip the HUBER Manhole Covers with gas springs, which we have now been doing for more than 30 years as a matter of principle. The complete range of HUBER Manhole Covers is "Made in Germany" or even more correctly "Made in Berching". Many of our customers have already taken the opportunity to visit our production facility. Thanks to modern and optimised production processes as well as motivated employees, we are able to withstand the price pressure of cheap foreign products. The HUBER anniversary cover HUBER stainless steel covers have now been on the market for 50 years and for us this is a welcome occasion to take a look at all the customer requests from home and abroad that we have collected over the years. We set ourselves the goal of fulfilling (almost) all customer wishes in an "anniversary cover", and the result is the innovative HUBER Manhole Cover SD50 SAP (Safe Access Pro) . This HUBER cover made of stainless steel chequer plate has an integrated fall protection which can be loaded up to 200 kg, concealed ventilation openings, seal on the underside of the cover and a recessed lock to name the most important features. 50 arguments for the HUBER Manhole Cover SD50 SAP (Safe Access Pro) Below are the 50 most important customer requests from A-Z: Lift-off protection through inner lugs Operating key included Load-bearing up to 500 kg Ventilation possible Digital locking systems Stainless steel Burglar-resistant according to DIN 1627 Easy to handle Compliance with ISO 9001 Spare parts available for many years Colour design possible Odour-tight Consistently high quality Replaceable rubber seal Hygienic Customisable Insect-proof Integrated fall protection Security of investment Durable Material options (V2A, V4A) The most economical solution in the medium term Sustainability Standard-compliant according to DIN 1239 Visually appealing Pollen filter or odour filter Inexpensive due to series production Quality control Stainless Back-friendly due to gas pressure spring Back pressure proof Fast delivery from stock Self-retracting arrestor Safety mortise lock can be retrofitted Special sizes and designs Stable Surface-watertight Flood-proof Monitoring by magnetic contact Different frame variants Concealed hinges Different locking systems Low-wear seal Brass closure cover Full bath pickling Completely made in Germany Compliant with regulations and rules (DGUV) Thermal insulation possible Maintenance-free Material completely recyclable You can always rely on us: Our cover is the original HUBER cover - everything else is a copy![...]

[...]Buxton STW, UK HUBER are pleased to of completed the last phase of a project at Buxton STW for Severn Trent Water. HUBER had been involved in various aspects of the site since the original upgrade in 2003 so we had a lot of knowledge of the existing inlet works and the problems it suffered with. By early engagement with both Severn Trent Water and the successful contractor Mott Macdonald Bentley we were able to involved with the project from the outset and deliver a successful solution. Project Profile Buxton STW serves the town of Buxton and its surrounding areas, HUBER had been involved in the site since 2003 when a major upgrade was carried out the inlet works and a subsequent MBR plant was installed downstream. Since this project HUBER had been regularly engaged to look at improving the effectiveness of the inlet works and screenings handling plant to improve the screenings removal to lessen the impact on the downstream equipment, there were challenges surrounding this due to the location of the existing screens and macerator setup. As part of the AMP6 programme of works it was decided amongst other things that a new inlet works and screenings handling facility would be built to improve the screenings removal on an unused part of the site, the site is located in a narrow valley and space is limited. This lead to several challenges and involved a phased installation. HUBER Technology Supplied: 2 x HUBER Belt Screen EscaMax® 6000x1152/6 60o 6mm perforated plate screens. 2 x HUBER Screenings Wash Press WAP® L 4 screenings handling plant 1 x HUBER Launder Trough 1 x Static Stone Trap Objective The primary objective was to provide new 6mm inlet screening to protect the downstream process from screenings and other debris and also provide screenings handling plant to wash and compact the removed screenings. Solution As we had been involved in various aspects of the site since the original upgrade in 2003 we had a lot of knowledge of the existing inlet works and the problems it suffered with. By early engagement with both Severn Trent Water and the successful contractor Mott Macdonald Bentley we were able to involved with the project from the outset. Each screen supplied was required to handle a flow rate of 381 l/sec working on duty/duty basis with the subsequent screenings handling plant being able to handle 4m3/hr of screenings. A further challenge was the location of the screenings handling plant, this required in the region of 25 metres of launder trough to transport the screenings. The new inlet screenings solution has been found to be very effective. Product Profile HUBER EscaMax® Belt Screen – The EscaMax® complements the well-known HUBER program for municipal and industrial wastewater screening, as it is particularly well suited in situations where excellent separation efficiency is required in deep channels with high water levels. Featuring a low installation height above ground level even in deep channels, suitable for a very wide range of applications through innovative design HUBER Wash Press WAP® L - Screenings handling plant designed for any application, featuring a dewatering performance up to 45 % DS and a weight reduction up to 75 %, and like all HUBER products manufactured entirely from stainless steel “Having been involved with this project since the original upgrade in 2003 it was great we were engaged early to deal with the complex challenges of building this inlet works and to keep the works running during the installation period. We are confident that the equipment supplied will provide the end user with a vast improved performance of the inlet works and downstream processes.” Richard Willis-Area Manager[...]

[...]Uttoxeter, UK HUBER Technology recently completed a project for Severn Trent Water at Uttoxeter STW, between Derby and Stoke on Trent. HUBER Technology were engaged on the project in 2019 with the project being installed in late 2021 and then commissioned later that year. This project was part of the upgrade to the site at Uttoxeter to improve the sludge thickening on site and follows the successful installation of a pair of HUBER DB units at Cannock STW. HUBER Technology Supplied 1x HUBER Sludge Gravity DrainBelt Thickener DB 1.0 complete with polymer dosing system and thick sludge discharge pumps Objective The primary objective was to improve the sludge thickening on site by the provision of a new gravity belt thickener. Solution For the sludge thickening the sludge was a SAS and the requirement for the throughput was 35.4m 3 /hr at a thickness of 0.3 - 1% D.S. A dry solids of >6% was required for the outlet. The solution also included the provision of the polymer dosing system. Product Profile The HUBER Belt Thickener DrainBelt is especially designed for sludges with poor settling properties: Minimised coagulant consumption due to efficient distribution Constant thickening result due to the long sludge residence time on the filter belt Increased thickening results due to a ramp installed to decelerate the sludge prior to being discharged A variety of filter belt qualities to meet specific “Early involvement with contractor and using the lessons we had learnt on the Cannock project enabled us to quickly develop a solution for this project to suit the thickening requirements needed, Severn Trent Water should hopefully see the huge benefit this technology brings to the downstream process very quickly.” Richard Willis-Area Manager For more information please contact Rachael Harvey 01249 765000, email Rachael.Harvey@huber.co.uk[...]

[...]Kinmel Bay, Wales HUBER Technology recently supplied, installed and commissioned three HUBER Belt Screen EscaMax®, a 6 mm 2D perforated plate fine screen and two HUBER Screenings Wash Press WAP® L BG8’s to Kinmel Bay, a Dwr Cymru Welsh Water coastal site in North Wales. Each HUBER EscaMax® Screen was designed for a hydraulic flow of 450 l/s. The existing inlet works contained two tank mounted Longwood’s escalator screens and could cater for 900l/s. They struggled to deal with the incoming flows, overtopped and bypassed regularly. With a new development of 1700 new houses, the existing works was condemned and a new open area was set aside for new inlet works on site. The new inlet works would be required to screen a total of 1250l/s. JN Bentley considered the use of hydraulic modelling to optimise the layout and to ensure hydraulic performance of the new inlet works and commissioned a scale physical hydraulic model. HUBER and Dwr Cymru Welsh Water visited the scaled physical hydraulic model and got to see first-hand the model in operation. The model layout was altered as a result of the model testing, the grit trap was rotated 90° in line with the inlet channels, and a low baffle wall was built to aid flow into the rest of the works. Once the results from the physical model were approved an order was placed with HUBER and work started on site. Installation of HUBER EscaMax® inlet screens and HUBER WAP® L commenced in Feb 2019. Full commissioning, optimisation and the provision of O&M Staff training of all the new equipment. HUBER Technology Supplied 2 No. 5000/952/6 HUBER EscaMax ® Screens with 6 mm perforated plate screen elements for a hydraulic throughput of 450 l/s per screen. 1 No. stainless steel “U” shaped 300mm launder. 2 No. HUBER WAP®L 8S Wash Presses suitable for a screenings throughput of 8 m3/hour.

Building the physical model gave Dwr Cymru Welsh Water the confidence that the right equipment was proposed for this site. We are confident that the equipment supplied will provide the end user with a vast improved performance of the inlet works and downstream processes.” Adrian Heneghan - Area Manager for HUBER Technology Key Benefits of HUBER Technology's Solution Fully tested solution using a fully scaled hydraulic model Choice of perforation sizes on the EscaMax® with a screening capture ratio of 84% and maintenance free ceramic bearings WAP® L –screening capture ratio of up to 18m3/h with a low wash water requirement and volume, weight and disposal costs reductions up to 85% 500 + UK installations For more information please contact Rachael Harvey 01249 765052, email Rachael.Harvey@huber.co.uk[...]
