[...]Manfouha, Saudi Arabia HUBER SE has won the first of three major projects in the field of solar sewage sludge drying in the Saudi Arabian capital Riyadh. The long-standing customer Alkhorayef Water&Power Technologies has placed an order with HUBER SE for the supply of 50 lines of HUBER Sludge Turner SOLSTICE®. This also includes the automatic sludge feeding with HUBER Screw Conveyors of a total length of approx. 900 metres. The contractor Alkhorayef Water&Power will operate the Manfouha wastewater treatment plant for a period of 15 years and expand it with various process steps such as solar sewage sludge drying. After the Bahr El-Baqar plant (Egypt), Manfouha will probably be the world's second largest plant for solar sewage sludge drying. The plant will probably not make it into the Guinness Book of Records, but it emphasises HUBER SE's leading market position in the drying sector all the more. We hope to be able to report on further sales successes in the field of solar drying soon. Thanks again to all our colleagues who have supported us in this very ambitious project.[...]

[...]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![...]

[...]Houston, TX USA In August 2017, Hurricane Harvey hit the Texas Gulf Coast and struck it hard. The devastating category 4 hurricane caused unprecedented flooding. In addition to more than $125 billion in property damage, the storm completely destroyed hundreds of thousands of homes. Within just four days, more than one metre of rain per square metre fell in many areas in the Houston region, making Harvey the rainiest storm ever recorded in the United States. Since Hurricane Harvey, the Houston region has repeatedly experienced severe storms, which is why the National Weather Service (NWS) has labelled Houston ‘America's Flood Capital’. The counties in the Houston region have a complex system of dams, pumping stations, reservoirs and retention basins. Fort Bend County, a county in southwest Texas, is part of this system and has more than 100 miles of dykes to contain floodwaters. Fort Bend, TX: pump station discharge and capacity improved 400% In response to Hurricane Harvey, the Fort Bend, TX Levee District No. 2 embarked on a major upgrade project to increase the flow and capacity of one of its pump stations by 400%. The goal of the project was to protect the area around the district from 100- year floods in the future. At the heart of the pumping station are seven newly installed vertical turbine pumps with an output of 1,500 HP. Together, these pumps have a total capacity of 63,000 l/s. HUBER screening technology for successful operation of the pumping station HUBER was commissioned to supply the necessary screens for the successful operation of the pumping station. This essential cleaning stage protects the downstream pumps from any contamination that usually occurs during flood and rain events. 6 HUBER Coarse Screen TrashMax® In co-operation with the engineering office, the plant constructor and the owner of the pumping station, the HUBER Coarse Screen TrashMax® with its unique rake design was selected as the screen of choice. The screen, whose main function is to protect downstream equipment, offers a uniquely high intake and discharge capacity in addition to high operational safety and reliable capture of bulky screenings. HUBER was therefore commissioned to manufacture and supply six HUBER Coarse Screen TrashMax® units. The 11.5 metre high screens have a bar spacing of 76 mm and fit perfectly hydraulically into the six almost 2.5 metre wide channels. These are located in the inlet of the pumping station next to the dyke area. The hydraulic capacity of each individual screen is up to 12,000 l/s. The hydraulically largest pumping station of its kind in Texas The ‘André D. McDonald Pumping Station’ in Sugar Land, TX was successfully commissioned in October 2021. Hydraulically, it is the largest of its kind in the state of Texas. It provides an effective measure to protect the homes, businesses and hospitals served by the district. HUBER is proud to be a part of this project.[...]

[...]Lyon, France In the south-west of Lyon, France's third largest city, the new modern La Saulaie district is currently under construction. It will provide new flats and houses for more than 2,000 people as well as commercial space, parks and leisure facilities. The existing district on the banks of the Rhône is being modernised and extended on the currently unused site of the French railway company SCNF. Sustainable energy supply As the issue of sustainability plays a similarly important role in France as it does in Germany, a sustainable energy supply for the district was particularly important to the project developers from the city of Lyon. The nearby sewer offers ideal conditions for the district’s heat supply. The Engie SA group had already been awarded the contract as energy supplier in 2021. HUBER technology for energy recovery In the planning phase, HUBER was able to score with reliable machine technology and more than 14 years of experience in the field of energy from wastewater. Our subsidiary HUBER France received the order for the supply, installation and commissioning of six HUBER Heat Exchangers RoWin14 in 2024. Performance data Wastewater flow: 336 l/h (1,200 m³/s) Wastewater temperature: 11 °C – 23 °C Heating capacity in winter: 2.9 MW Cooling capacity in summer: 4.6 MW More information on the official website of the project: https://www.projet-lasaulaie.fr/le-projet/decouvrir-le-projet[...]

[...]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 .[...]

[...]United Utilities, Warrington, England Background In 2017, United Utilities started work on a four-year improvement project at Blackburn and Darwen WwTW. This work included: Extending the current works at Blackburn WwTW to construct new tanks, buildings and improve the treatment process. Taking existing wastewater flows from Darwen WwTW through to Blackburn WwTW by installing a new connecting pipe and upgrading the existing tanks. Constructing new storm tanks and new pipeline to transfer wastewater to Blackburn WwTW from Nabs Head WwTW. Blackburn WwTW treats principally domestic crude sewage from the Blackburn catchment, with two major additional contributions; a high strength trade effluent from a brewery and an ammonia rich return liquor flow from the sludge treatment plant. It was identified at an early stage the benefits of maintaining a gravity solution through the treatment process, taking advantage of the natural topography of the site and avoiding the need for the ongoing costs of interstage pumping. Scope of the project A new inlet channel to feed a 72,000m³ in situ concrete structure was built to house the innovative Nereda® aerobic granular biomass technology. The Nereda® system treats crude sewage that has only received preliminary treatment and has been developed to treat the full flow and peak load at the works; i.e. a complete replacement and expansion of the existing wastewater treatment plant with a flow to full treatment (FTFT) of 3,000 l/s. The Main Contractor awarded the sub-contract to HUBER Technology in 2019 for 3x HUBER Rotary Screw Thickener S-DRUM sludge thickeners designed to process sludge arising from the Nereda® process. This contract followed on from a similar project United Utilities completed at Kendal WwTW where again, the S-DRUM sludge thickeners process sludge arising from the Nereda® process. Sludge thickening process requirements: Sludge type: From the Nereda® process Maximum dry solids content of incoming sludge: 0.80 % Maximum outlet sludge concentration: 5.0 – 8.0 % Maximum throughput required: 153 m³/hour Operating periods: Up to 24 hours per day 7 days per week Mode of thickener operation: Duty/assist/standby Solids recovery minimum: 95% HUBER Technology scope The design, manufacture, supply, delivery, mechanical installation, of: 3 x (duty/assist/standby) HUBER S-DRUM 4L sludge thickeners c/w flocculation reactors. 3 x sets of polymer mixing valves and injection rings. 3 x thickened sludge pumps. Commissioning and the training of O&M staff. The majority of S-DRUM sales have been used for thickening SAS, co-settled and mixed sludge from conventional processes. The experience gained dealing with sludge arising from the Nereda process will showcase the S-DRUM for the increased take up of this process in the future. Unlike other drum thickeners that are predominantly installed horizontally, the S-DRUM is installed at an angle i.e. inclined. This has several advantages, with 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. 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 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 United Utilities area for the Kendal WwTW Project and even better to receive a second contract to supply them on this high profile Blackburn WwTW project. I have tracked the performance of the S-DRUM’s since I started with HUBER technology over 25 years ago and I am confident they will prove as popular and reliable as they are in many other areas of the UK and Ireland. ”[...]

[...]Cannock STW, UK HUBER Technology recently completed a project for Severn Trent Water at Cannock STW, north of Birmingham. HUBER Technology were engaged on the project in 2018 with the project being installed in late 2019 and commissioned in 2020. Project Profile This project was part of the upgrade to the Four Ashes and Cannock STW sludge treatment capability to include finer screens and provide sludge thickening. HUBER Technology Supplied 2 x HUBER Sludgecleaner STRAINPRESS® 290 5mm Sludge screens including Control Panels to Severn Trent Water Specification and a 6m high gantry to mount the screens on. 2 x HUBER Sludge Gravity DrainBelt Thickeners DB 2.0 complete with polymer dosing system and thick sludge discharge pumps Objective The primary objective was to improve the sludge screening on site to prevent screenings that had bypassed the inlet works entering the downstream process, which included the new gravity belt thickeners. Solution The solution formed two parts, the sludge screening and then the sludge thickening. The throughput required for the sludge screening was 60m³/hr at an incoming thickness of 2% D.S. Two screens were selected to allow for a duty / standby operation. The screens were pre-installed onto the gantry in HUBER Technology’s UK workshop to allow the control panels to be fitted and cabled to the screens. This reduced the onsite installation time with the offsite fabrication and reduced the need for working at height on site. For the sludge thickening, the sludge was a mixture of primary and SAS and the requirement for the throughput was 96.72m 3 /hr at a 1% D.S. with both thickeners in operation. A dry solids of >6% was required for the outlet. Product Profile HUBER STRAINPRESS®– Sludge Screening – To remove solids and rags from imported municipal sludge prior to thickening or dewatering. Benefits include high solids removal, low energy consumption, 385 UK reference sites, simple robust design and fully automated operation. The HUBER Belt Thickener DrainBelt is especially designed for sludge’s 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 requirements “ Early involvement with NMCN the contractor through site visits and meetings enabled a proven solution to be designed for both the screening and thickening requirements; Severn Trent Water should hopefully see the huge benefit this technology brings to the downstream process very quickly. ” Richard Willis-Area Manager[...]

[...]Chippenham, UK HUBER Technology recently completed a project for Wessex Water at our local treatment works Chippenham STW in Wiltshire. HUBER Technology were engaged in the design phase of this project prior to order in 2019 and were awarded the project in 2021 and finally commissioned in early 2022. Project Profile Chippenham STW serves the town of Chippenham and its surrounding areas with a PE of approximately 40,000 people. HUBER had been involved on and off in the site since the late 1990’s. The site had 3 2M wide elevated inlet channels, 1 bypass channel and 2 Screen channels with 6mm INKA Step Screens that discharged into a launder; screenings were treated by a single screenings handling unit. Pumped Flow to the inlet works was pumped via 3 Inlet pipes. The INKA Step screens struggled with the increased flow to the site over the 20+ years since installation. They also struggled during storm conditions to deal with the large slugs of rag flushed down the pipes after a dry spell. This resulted in the inlet channels over topping onto the top level and the ground below the inlet works. 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 site hydraulics and existing screens and screenings handling setup. Due to hydraulic constraints, the inlet works needed to be raised by 900mm, this improved the velocity of the flow through the works. HUBER Technology Supplied: 2 x HUBER Belt Screens EscaMax® V escalator screens 5000x1652/6 60 o 6mm perforated plate screens . 2 x HUBER Screenings Wash Press WAP® L 6 screenings handling plant 1 x HUBER Launder Trough Objective The primary objective was to provide new 6mm inlet Duty/Asist screening to protect the downstream process from screenings and other debris and also provide similar Duty/Assist screenings handling plant to wash and compact the removed screenings. Solution Being our local treatment works, we had been involved in various aspects of the site since the late 1990’s we had plenty of knowledge of the existing inlet works and the problems it suffered with. By early engagement with Wessex Water meant we were able to be involved with the project from the outset. Each screen supplied was required to handle a flow rate of 900 l/sec working on duty/assist basis with the subsequent screenings handling plant being able to handle 6m 3 /hr of screenings also working in Duty/Assist mode. A further challenge was the location of the screenings handling plant, to avoid blocking the access road around the site, 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. “It was great to re-engage with Wessex Water to get our local treatment works upgraded. We were delighted to engage 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 our design and the equipment supplied would provide the end user with a vast improved performance of the inlet works and downstream processes.” Adrian Heneghan – Area Manager[...]

[...]HUBER Technology recently completed two projects for two hotels, one located in the North of Ireland and the second one located in Northern Ireland. Both of these projects improve the sewage treatment capacity for these resorts to reduce maintenance and downstream blockages. Project Profile Both of these projects were upgrades to the sites effluent treatment plant to include for a provision of upstream screening. Due to the differing nature of the sites the project at Harveys Point hotel featured a screen in concrete channel whilst the project at Lusty Beg the screen was installed in a stainless steel tank HUBER Technology Supplied 1 x HUBER Ro9 Micro Strainer suitable for mounting into a concrete channel (Harvey’s Point) 1 x HUBER Ro9 Micro Strainer suitable for mounting into a tank (Lusty Beg) 2 x HUBER Control Panels 2 x Full mechanical and electrical installation 2 x Commissioning of all equipment Solution Based on the flow rates for both sites the smallest Ro9 300mm diameter screen was selected, this size of screen will pass around 40 l/sec of sewage flow. The screenings were discharged into a wheelie bin with a LongoPac bagging unit to reduce any odours. Product Profile The HUBER Micro Strainer ROTAMAT® Ro9 operation is based upon a unique system that allows the combination of screening, washing, transport, compaction and dewatering in a single unit. Depending on the screen bar spacing or perforation and screen size (up to 700 mm screen basket diameter), the throughput can be individually adjusted to specific site requirements. The screen can be installed either directly into a channel or into a separate tank.[...]
