[...]Wanlip - Leicester, UK A HUBER Technology Wastewater Case Study HUBER Technology recently completed a project for Severn Trent Water at Wanlip STW on the outskirts of Leicester. This was a project that had been looked at for a long period of time but was commissioned in early 2020. Project Profile This project was part of the upgrade to the sites indigenous sludge treatment to replace ageing step screens, which were installed in the 1990’s. HUBER Technology were first involved in the project in the late 2000’s to see what options were available to improve the process. The challenge was to improve the sludge screening on the site but we were constrained by the location of the screens at high level receiving the pumped sludge. HUBER Technology Supplied 2 x HUBER Sludge Acceptance Plant ROTAMAT ® Ro3/1200/6 tank mounted sludge screens 2 x HUBER Severn Trent Water specification control panel Objective The primary objective was to improve the sludge screening on site to prevent screenings that had bypassed the inlet works entering the picket fence thickeners and further downstream parts of the treatment process within the constraints of the high-level sludge screening area. Solution As outlined above this was a project that HUBER Technology had been involved with for a long time with various contractors. We had previously looked at utilising the existing 600mm concrete channels but these were no longer wide enough for the increased flow rate. The current screens were installed in a building but this was deemed to be beyond repair and was removed, this allowed clear access for the new screens. The tank mounted screen were mounted alongside the existing channel retaining the original upstream balancing tank. Flow from the balancing tank then flowed to each of the two screens whilst maintain a bypass channel between the screens if it was required. The screens sludge was discharged back into the original channel prior to it being fed to the adjacent picket fence thickeners. Each screen was provided with its own dedicated control panel fully built to Severn Trent Waters specification. Product Profile HUBER Sludge Acceptance Plant ROTAMAT ® Ro3 – The robust and efficient Ro3 has become the most popular system of its kind.

[...]Milford Haven, Wales Huber Technology recently completed the installation of new escalator inlet screens and screenings handling plant for Welsh Water (DCWW) at Milford Haven STW. Project Profile Having completed the installation of escalator screens and screenings handling at Garnswlt STW working direct with DCWW and their South West Capital Delivery team, HUBER were asked to look at a similar type of project at Milford Haven STW. The main difference between the two sites was that the site at Milford Haven was a raised inlet works and located inside a building. This was from the outset of the project a challenge for all involved with the space available being very limited and all the equipment supplied would have to be Ex rated. The existing INKA step screens and Parkwood compactor were close to the end of their asset life. HUBER had previously carried out repairs on the inlet screens just 3 months prior to our visit and had warned that spares for both existing screens were getting more difficult to procure. Also, it was noted that the existing screens were struggling to cope with the first flush, which required the local operator to remove large volumes of screenings by hand into a receptacle and dispose into a skip on regular basis and thus becoming a major health and safety issue. An initial site survey undertaken by Adrian Heneghan, HUBER’s Area Sales Manager, highlighted that this could not be done without some help from a local DCWW contractor. Whitland Engineering were the closest and came recommended by DCWW. Another site visit was made and between HUBER and Whitland, scopes of work were agreed and an order was placed on both companies by DCWW to proceed with the project. Huber Technology Supplied 2 off EscaMax® 4000/652/6 Duty/Standby for 400l/s each 1 WAP/L BG4 Local Control Panels Local Push Button Stations Objective The challenge of getting 2 new escalator screens and a WAP/L compactor into a confined space while keeping the site running was a major feat in itself. Phase 1 of the project was getting the HUBER control panels and push button stations delivered 2 weeks prior to the screens. This allowed Whitland Engineering time to get them into position and pre-cabled ready for the new equipment. Phase 2, was for the mechanical installation. The site had upstream storage for 4-5 hours which allowed a reasonable time to remove the old Parkwood compactor and install the new WAP/L BG4 screenings handling unit into a temporary position so as not to hinder the installation of the screens. Phase 3, with the WAP/L running, one of the INKA step screens was isolated and removed allowing the other to run and keep the plant operational. The new EscaMax® was then installed and cabled ready for commissioning. Phase 4 involved removing the 2nd INKA step screen and installing the other EscaMax® unit. Again, once cabled the screen was then ready for commissioning immediately. Solution Throughout all the phases of the project execution, detailed planning and effective communication between Huber Technology, Whitland Engineering and the DCWW capital delivery team was essential. A collaborative approach and good working relationship between the 3 companies ensured that this challenging project was delivered on time and within budget. David Alford – Contracts Engineer – Huber Technology: “As always with projects having a large amount of site work we encountered a few challenging moments throughout the installation phase but by good communication and working closely with Whitland Engineering we were able to overcome these with a successful outcome and a satisfied customer.” Mark James – Milford Haven Site Operator: “Thanks to all involved in getting these screens in and running while keeping the site running. I can now spend more time looking after the rest of the site without having to watch the inlet screens and manually remove screenings. From a health and safety point of view, this is a bonus. The screens and screenings handling are all working really well.”[...]
[...]All WaSC’s (water & sewage companies) are under increasing scrutiny relating to unauthorised discharges to watercourses. The task they now face is an eye watering number of stormwater overflows that need addressing in the coming years. This is enormous challenge & is likely to generate an unprecedented demand for screening solutions. HUBER Technology are confident they are best placed within the existing supply chain to provide risk free screening solutions to assist with this daunting challenge. With almost 1500 weir mounted screens already supplied in the UK & Ireland (1,000’s globally), we are confident that the adaptability of our suite of the ROTAMAT® RoK weir mounted screens sets us apart from other suppliers all of whom can tackle straightforward applications i.e. where screenings are retained within the network. However, what happens if this solution is not viable? This is where HUBER Technology can add significant value to the optioneering process & provide some very innovative solutions. Since the mid-late 1990’s, when mechanical screens were first used to protect watercourses, ROTAMAT® RoK screens have been used to tackle double digit spills up to spills of several thousand litres per second. All of the ROTAMAT® RoK weir mounted screens can be utilised to retain screenings within the sewer network, & below we have provided typical details: ROTAMAT® 0° RoK1 weir mounted screen = Zero additional head: Generates the lowest top water levels of any screen on the market. Relief weir/level of the back plate is very low & can be set to weir height in some cases i.e. no increase in levels regardless of screen operation or power availability. Use of a chamber with integral flow control bulkhead means screenings enter the pass forward flow unhindered. Unique dissipation zone acting as an orifice is incorporated into the screen design to ensure flow cannot short circuit the screen thereby adding to the continuation flow. Mounted on the dry side of the weir. Can be utilised to discharge screenings into separate screening handling plant to lighten the load on downstream inlet works or for end of line applications. ROTAMAT® 60° RoK1 weir mounted screen Mounted on top of the weir so is the only real option for low-sided weir applications. Fits in chambers where the inlet pipe diameter dictates the main channel is too narrow for ‘wet side’ screens. Up & downstream relief weirs can be set lower than screen back plate to lessen TWL in screen/power failure scenario. Ideal where surcharging of the outfall occurs or there is limited space on the outfall side of the weir. ROTAMAT® RoK2 upward flow screen Screen front plate acts as a natural scum board to keep floating debris out of the screen. Mounted on the foul/wet side of the weir. Returns screenings to the continuation flow via a cut out in non-drive endplate. Centreline of screen can be located well below weir for optimum usage of the screen open area resulting in lower head above the weir. Can be installed in series to deal with extremely high spill flows. Adaptable to all stormwater screening applications There are many scenarios where this is not possible to retain screenings within the sewer network & other methods of dealing with the screenings have to be considered. This is where the ROTAMAT® RoK weir mounted screen range comes into its own offering the upmost versatility. Bespoke ROTAMAT® 0° & 60° RoK1 weir mounted screen applications: Outfalls from pumping stations where screenings are returned to the network using novel screen adaptations. Outfalls from pumping stations & storm tanks with screenings processed when removed. Storm tanks where floating material is retained until flow subsides. 3 or 6 x stormwater overflows where screenings are removed at spill source to reduce loading to downstream inlet works. End of line scenarios. Bespoke ROTAMAT® RoK2 weir mounted screen applications: End of line scenarios - Screenings pushed through a bulkhead wall into wet well pumping station or into separate screenings handling plant. 3 or 6 x stormwater overflows where screen can span a double sided weir arrangement. Modular design of all ROTAMAT® RoK screens allows maintenance to be undertaken in situ or where personnel access is to be avoided cradle lifting systems can be supplied. DfMA solutions HUBER Technology has worked with various prefabricated CSO chamber providers where the appropriate ROTAMAT® RoK screen can be installed in the workshop prior to delivery to site. Ideal where disruption to the public, traffic & businesses needs to be kept to an absolute minimum. Risk free, versatile & innovative Longest proven record of accomplishment in the UK & Ireland. Performance tested & verified at all recognised UK research/testing facilities. 3 different orientations / 4 different diameters / 16 modular screen lengths available - Rarely an application we can’t provide a solution for.

[...]Sleaford, UK Anglian Water approached HUBER in January 2006 and asked us to offer a solution for resolving problems at their Sleaford plant where large amounts of screenings passing through the inlet works and impairing downstream processes. The operators were also experiencing problems with their existing screenings processing system. In co-operation with a local contractor we proposed to remove the existing screen and screenings processing system. We offered a pair of HUBER Belt Screen EscaMax® 4000 perforated band screens with a width of 752 mm and a capacity of 101 l/s, installed at an angle of 60° within the channel, a WAP/SL size 2, and control panels. The local contractor would carry out the removal of the failing equipment, supply of a launder channel and complete mechanical and electrical installation. Our proposal was accepted by Anglian Water and an order was placed in April 2006. The plant was commissioned in November 2006 and operator training was carried out in January 2007. The operators are delighted with the new equipment and we are using this site as an excellent reference for the HUBER EscaMax®.[...]
[...]Melton Mowbray, UK HUBER Technology are pleased to of recently completed the installation and commissioning at Melton Mowbray STW. Project Profile Melton Mowbray STW is a medium sized activated sludge works, treating a PE approx. 68,000. The works treats a combination of both domestic and trade effluents. The new Melton Mowbray STW is designed to cater for increased treatment flows equating to a design horizon population equivalent of 123,328 (82% growth) and a tightening of the phosphorus and ammonia permits. A significant proportion of the influent is from trade waste. HUBER were heavily involved in the design and planning of the new inlet works with MWH and Severn Trent Water. - Inlet works refurbishment replacing the two existing 6mm screens with three 6mm screens and installation of wash compactors. Early involvement with MWH, through site visits and meetings enabled a proven solution to be designed for both screenings and screenings handling requirements. Severn Trent water should hopefully see the huge benefit this technology brings to the downstream process very quickly. HUBER were involved in part of the innovative solutions to ensure the re-use of the existing inlet structure in lieu of a new structure. The existing two HUBER screen installation with centre by-pass channel was designed to be replaced by three new HUBER Belt screens EscaMax® and two HUBER Wash Press WAP® L compactors. This was further complicated as the refurbishment had to fit the existing inlet works. This was achieved by the provision of a new bypass pipe outside the inlet works structure and the use of the existing centre bypass channel to house the third screen. We worked collaboratively with MWH to ensure that this was achieved. HUBER Technology Supplied 2 x HUBER Belt Screen EscaMax® 4000x752/6 60° 1 x HUBER Belt Screen EscaMax® 4000x952/6 60° 2 x HUBER Wash Press WAP® L 8 Interconnecting Launder Details of the process including for screens: Total flow rate 548 l/s. Peak flow per screen 183 l/s Duty/assist/assist Screen width 752 = 2.85 m3/h and screen width 952 = 3.6m³/h, total capacity 9.3 m3/h all @ 50% blinded Details of the process including for screenings handling: 9.4 cu.m/hr duty/standby Screens 0.733 l/s @ 5 Bar. Screening handling Peak 1.5 l/s at 2 bar in operation Objective & Solution The main objective for us was the efficient refurbishment of the inlet works with installation of three new HUBER screens and two HUBER wash compactors on a phased changeover at the inlet. HUBER completed the mechanical installation over three stages with commissioning being completed in stages (in between the install stages) before the next machine was installed as the site needed to have at least one EscaMax® running throughout the installation process. HUBER Belt Screen EscaMax® Product Profile World class screening efficiency- 84% average solids capture ratio Unique sealing design ensures continued efficiency with minimal maintenance No requirements for self-adjusting brush due to innovative design Range of perforation sizes & screen installation angles available 300+ installations UK & Ireland HUBER WAP®L Wash Press Product Profile Screenings from launder systems or direct from screens where screen wash water rate is high Wet screenings throughput up to 24m3/hr Volume, weight & disposal cost reduction up to 85% Low power & wash water consumption 600+ installations UK & Ireland David Foster McBride (Area Sales Manager) commented on the project “Early engagement with the customer allowed for a suitable innovative solution to be selected to handle the design parameters and be successfully delivered within the existing inlet works limitations.

Following successful award onto Thames Water framework for the supply of this equipment in October 2011, we were then approached by Black & Veatch to provide the equipment. Additional capacity has been added to ensure that the increased flows can be treated and 3 x HUBER Disc Filter RoDisc® size 22 were selected for the duty. The project was ordered following detailed discussions in May 2012 and has now been delivered to site in October 2012. The plant is due for commissioning and operation in early 2013.[...]
[...]Great Britain Three recent installations are now helping poultry slaughterhouses to reduce their sludge disposal costs and remove their reliance on tankering sludge off site. Background With ever increasing sludge disposal costs and tightened restrictions on spreading sludge on land (particularly over the summer months), HUBER were approached to provide dewatering of the sludge on three poultry slaughterhouses. The sites had identified the potential for savings and wanted to evaluate treatment options. Since the three sites operate similar processes, a single trial was conducted to evaluate the screw press performance. HUBER were able to offer an on-site trial using a containerised HUBER Screw Press S-PRESS unit, which was operated by site over the course of a month. This allowed the sites to confidently assess not only the performance of the machine but the ease of operation and minimal amount of time required from site operatives. Following the trial, the client was issued with a detailed report, so that they could evaluate both capital and operating costs. Solution Although the Screw Press and polymer batching plant supplied to each site was the same, each site had slightly different considerations for installation of the Screw Press on their site, including: Area available and layout of existing treatment plant, including location of sludge holding tank Size of skip/trailer to be used for cake disposalExisting buildings/structures HUBER have experience of operating Screw Presses mounted in containers, inside buildings, and on top of gantries with cake either dropping into a skip directly or using a screw conveyor to transport & distribute the cake across a long trailer. The customers were able to draw upon this knowledge to ensure that each installation was as practical as possible and cost effective, while being the right decision for that particular site. HUBER provided the full equipment scope for the client to incorporate into their installation, including: HUBER Screw Press S-PRESS I sludge dewatering screw press Automated polymer batching plant to flocculate the sludge Feed sludge and chemical dosing pumps In-line polymer injection and sludge mixing to mix sludge and polymer within an enclosed, small footprint Pre-programmed control panel to automate operation of the plant As a result of the three installations, the clients are have been able to significantly reduce their sludge disposal costs. In addition, vehicle movements are minimised, since the water removed from the sludge now goes to drain (after being processed by the on-site ETPs) rather than being transported away by costly road tankers.

[...]Beilngries, Germany The Beilngries wastewater treatment plant is located in the Altmühl Valley, a region very popular with tourists. The plant treats the wastewater of approx. 10,000 inhabitants. The digested sludge is dewatered three times a year over a period of two weeks using a decanter from a contractor. The practice of contract dewatering was then scrutinised for the following reasons: The long stacking of the digested sludge, also due to its cooling, combined with the high throughput rate on the decanter, led to poor dewatering results of only 20% dry matter content in the press cake. The disposal costs for the poorly dewatered press sludge were correspondingly high. The centrate water produced then also had to be stacked and returned as evenly as possible, which was labour-intensive, in order not to overload the biological treatment process and avoid peaks of return load. Recently, the digester has also been fed with large quantities of food waste/fat from the surrounding catering industry in order to significantly increase the gas yield and thus the electricity generation from the digester gas. However, the food waste contains high nitrogen and phosphorus loads, which further jeopardised compliance with the limit values in the wastewater treatment plant's effluent during discontinuous sludge dewatering via the centrate. HUBER Screw Press Q-PRESS® 620.2 wins the contract After several on-site performance comparisons of different sludge dewatering suppliers, the contract for a permanently installed sludge dewatering system was awarded to HUBER SE with the Screw Press Q-PRESS® 620.2. In addition to the screw press, the complete new construction also includes the pump and measuring technology including online solids measurement, polymer preparation, polymer mixing into the sludge, press sludge conveying technology and the electrical control system with control system connection by Spangler. The planning for the complete new building was significantly influenced by the plant manager Mr Porkert with the focus on: Extensive automation and process visualisation Control technology safety concept for sludge and gas treatment Possibility of dewatering 45°C warm digested sludge from the digester brine Resistance of the sludge path to coarse materials and sediments from the digester or the fat intake Consistent discharge of corrosive process air Maximum flexibility when filling and removing the sludge containers Performance data from tests exceeded The performance data of the sludge dewatering system now exceed the results of the previously tested mobile HUBER demonstration plant. With a throughput of 5 m³/h, a dewatering degree > 28% DR is achieved. The screw shaft of the press operates at a maximum speed of 0.3 rpm, requiring an electrical power consumption of only 1 kW. The control system of the screw press automatically regulates the number of revolutions with the aim of maximising the dewatering result and minimising the filtrate load. Automation of the conveying system The fully automatic operation of the sludge dewatering system continues with the discharge of the dewatered sludge using a HUBER Screw Conveyor Ro8 TC as a distribution screw. Three containers can be filled without operator intervention by means of the automatically swivelling distribution screw. For example, five preset drop points can be approached for each container and filled to a desired height. This means that the volume of the skip containers can be utilised to the maximum without, for example, having to smooth out the filling manually before removal. The motorised position adjustment for the distribution screw and the discharge chute even allows several skips to be filled in layers at the same time. This function makes it possible to refill sludge to a skip after the sludge has settled or compacted. Some operators even report systematic air-drying of the dewatered sludge when several skips are filled alternately in layers. The automation of the conveyor technology does not end with the filling of the skip: Before the containers are collected by the haulage contractor, the distribution auger automatically swivels into a safe parking position, allowing the skips to be collected safely and quickly, even without the intervention of the operator. HUBER SE would like to thank the client, the city of Beilngries, the head of the wastewater treatment plant Mr Porkert and the engineering office Goldbrunner from Gaimersheim responsible for planning, tendering and construction supervision for the trust they have placed in us and the very good, constructive and smooth cooperation.[...]
[...]Bremen, Germany A new future quarter for business, living, work, culture and leisure is currently being built in Bremen – with a sustainable energy supply from wastewater: Europe's once largest tobacco factory is being revitalised into the “Tobacco Quarter” building complex. The quarter has reinvented itself, turning an outdated industrial site into a prime example of urban development with its finger on the pulse of the times. It is one of the largest urban development areas in northern Germany. A new future quarter for business, living, work, culture and leisure is currently being built in Bremen – with a sustainable energy supply from wastewater: Europe's once largest tobacco factory is being revitalised into the “Tobacco Quarter” building complex. The quarter has reinvented itself, turning an outdated industrial site into a prime example of urban development with its finger on the pulse of the times. It is one of the largest urban development areas in northern Germany. The new Tobacco Quarter will utilise energy from wastewater for heating and cooling with the help of the HUBER ThermWin system. On average, 1 MW of thermal energy will be used for heating and around 0.4 MW for cooling building sections of the new urban quarter. The sustainable overall concept of the Tobacco Quarter was awarded the DGNB Gold pre-certificate by the German Sustainable Building Council (DGNB) in 2023. Technical solution together with swb and hanseWasser At an initial meeting in 2021, an inspection of an existing pumping station took place in order to assess the extraction situation. This took place with the parties involved in the project, hanseWasser Bremen GmbH and swb Services AG & Co. KG. Based on the wastewater volumes and temperatures, numerous potential analyses were carried out as part of a feasibility study. hanseWasser Bremen GmbH was able to provide extensive measurement data and it soon became clear that wastewater as a resource could make a major contribution to a sustainable energy supply for the new urban quarter. Experience utilised from existing HUBER system in Bremen swb Services AG & Co. KG, the sales company for technical services of Stadtwerke Bremen, the Bremen municipal utilities, contacted HUBER SE: One of the reasons for this was that HUBER had already supplied a plant for energy recovery from wastewater to hanseWasser Bremen GmbH about ten years ago. A HUBER Heat Exchanger RoWin size 4 reliably operates at the pumping station in Bremen. ”Exclusively positive feedback“ According to Frank Estler, Project Manager at swb Services, the reasons in favour of the HUBER ThermWin system were obvious: ”When looking for a suitable heat transfer system, two points were particularly important to us. The system had to have proven its efficiency in practice and the maintenance effort on the wastewater side had to be minimised. We received exclusively positive feedback from hanseWasser from the project in Findorff on both points and on the cooperation with HUBER.“ The HUBER ThermWin system The HUBER ThermWin system enables the heating and cooling of buildings by utilising the wastewater in the sewerage system as a regenerative energy source. The temperature of wastewater in the sewerage system is usually between 12 and 20 °C and hardly drops below 10 °C even in winter, which is why wastewater is an ideal energy source for operating a heat pump. All larger buildings and local heating networks are suitable consumers of the heating energy obtained in this way. Part of the wastewater flowing through the sewer is first passed through a HUBER water pre-screening solution (e.g. usually a screen such as the HUBER Pumping Stations Screen ROTAMAT® RoK4), which removes the coarse material from the wastewater. In the Bremen Tobacco Quarter project, the raw wastewater is pre-screened by a HUBER Rotary Drum Fine Screen ROTAMAT® RPPS 1400. The wastewater is then distributed into three HUBER Heat Exchangers RoWin, which are installed above ground and specially developed for wastewater, and then flows back into the sewer. Inside the heat exchanger, the heat is exchanged with the secondary circuit, which is coupled with the heat pump. Federal funding for efficient heating networks The HUBER ThermWin process utilises wastewater as a long-term secured and constantly renewing energy source to enable an environmentally friendly and sustainable process for heating and cooling buildings. Fossil fuels such as gas, oil or coal can be saved and CO 2 emissions minimised. In future, the Tobacco Quarter will save around 245 tonnes of CO 2 per year. This is why this project is subsidised by the Federal Ministry of Economics and Climate Protection (BMWK) under the Federal Funding Scheme for Efficient Heating Networks (BEW). With this funding measure, the BMWK supports the construction of new heating networks with a high proportion of renewable energies as well as the decarbonisation of existing networks. 1 MW for heating, 0.4 MW for cooling the Tobacco Quarter The plant for energy recovery from wastewater is expected to supply energy to the city quarter in October 2024. Three HUBER Heat Exchanger RoWin units will then utilise an average of 1 MW of thermal energy for heating and around 0.4 MW for cooling sections of the building. Another important contribution to sustainable and environmentally friendly building and urban planning with exemplary character – and a lighthouse project for HUBER.[...]
