[...]Machines for Sludge Thickening All common methods of sludge thickening with disc thickeners, screw thickeners and filter belts HUBER Disc Thickener S-DISC Machines for Sludge Thickening HUBER Belt Thickener DrainBelt Machines for Sludge Thickening HUBER Rotary Screw Thickener S-DRUM Machines for Sludge Thickening HUBER is able to offer all common methods of sludge thickening With regard to economical further treatment and disposal of sewage sludge, it is necessary to reduce the sludge volumes produced in the course of the wastewater treatment process. The volume reduction is achieved by separation of parts of the sludge liquor at different points in the sludge treatment process chain. The main field of application of thickening systems is volume reduction of primary and excess sludge prior to stabilisation. HUBER offers belt thickeners as well as screw thickeners and disc thickeners as filtration units. The seletion of the most suitable technology for individual applications depends on project-specific parameters, such as throughput capacity or operating and investment costs, but also on other criteria, such as operating reliability, flexibility and process complexity.[...]

[...]Magilligan, Northern Ireland HUBER Technology successfully completed the NI Water Magilligan WwTW scheme. Project Profile The Magilligan region is located on the north coast of Northern Ireland just north of the town Limvardy. This area is very popular with tourists and incorporates a Blue Flag beach at Benone as well as a significant portion of land designated as a Special Area of Conservation (SAC).It was concluded from an assessment that a single wastewater scheme for the Magilligan region would be the most cost effective solution whilst offering additional qualitative benefits for the area and its inhabitants and visitors. HUBER Technology Supplied 1 x HUBER Disc Thickener S-DISC size 1 & Control Panel Objective HUBER Technology’s success in Northern Ireland Water and with principal contractor Williams Industrial Services originally stems from a very well attended open day arranged by Area Manager Fred Neumann around the successful trial of a containerized RoS3 (now S-Press) at Enniskillen’s Silverhills WwTW back in 2002. Since then a significant number of screw presses and screw thickeners have been installed in the region, with the total number of units overall now being 65 at time of writing. HUBER have now discontinued the two smaller RoS2 (now S-Drum) thickener sizes in favour of the new size 1 and 2 RoS2S (now S-Disc) units. Though the customer’s operations and maintenance staff were naturally cautious of moving away from the S-Drum units that they were now overtly familiar and happy with, visits to reference S-Disc units elsewhere in the UK quickly appeased any such potential concerns and it was decided to try an S-Disc unit on the new Magilligan WwTW. Since commissioning in 2013, the site and area operations staff are incredibly pleased with the new unit and its process robustness at handling varied SAS flow rates, feed thicknesses and operating times due to the seasonal population fluctuations as a result of a number of large caravan parks in the catchment. So much so that more units have subsequently been ordered for installation in the area. Solution Northern Ireland Water required a throughput of 6.3 m³/h x 0.6%DS and a dewatering efficiency requirement of 6% DS and HUBER were pleased to supply the S-Disc, Flocculation reactor, poly mixing valve & injection ring and control panel. The installation was carried out by Williams Industrial Services and HUBER carried out the commissioning of the unit. Product Profile HUBER Disc Thickener S-DISC - Sludge Thickening Sludge thickening - to reduce storage on site and reduce tanker movements from site. Key benefits include; Low energy & polymer consumption Easy set up & low operator attendance Can be installed inside or outside Unique design & compact footprint Simple robust design Offsite build packages available “By working closely with the NIW Project manager, operations and process team along with the design consultant and the contractor, I was able to impress on them the potential of the new HUBER Disc Thickener S-DISC for this application and future sludge thickening projects. Knowing the reliability of other HUBER products, which they are currently using and the support which HUBER Technology provide, they agreed to take our product on for this application and to date operational reports on the S-DISC are very complimentary. The same has resulted in a further two units being ordered for the new Ballycastle WwTW” commented Fred Neumann Area Manager Scotland & Ireland. Aidan Diamond Williams Project Manager commented that “the S-DISC was installed and commissioned to a very high standard and produces a very good sludge output. It is easily maintained and operated.”[...]

[...]Roeselare + Beringen, Belgium HUBER SE will supply a total of five HUBER Belt Dryer BT units to the Belgian company Aquafin for the two sites in Roeselare and Beringen. The plants for drying and thermal utilisation of sewage sludge will treat a minimum capacity of 32,500 tonnes of dry substance or 120,446 tonnes of original substance with a dry residue (DR) content of 27% per year. In addition to the HUBER belt dryers, the scope of supply includes the entire wet sludge logistics, cooling water supply, exhaust air treatment for the dryer and bunker exhaust air as well as the treatment and storage of the dry sludge. The total order for HUBER SE for approx. 40 million euros was placed in mid-2023. Project constellation The project is carried out by a team of three companies: Contractor: Stadsbader Group Technology partner for sludge drying: HUBER SE Engineering and study: Sweco For the end customer Aquafin, this combines the strengths of a healthy construction company, a specialised technology partner in drying technology and an experienced engineering company with specific experience in the fields of hydraulic engineering, civil engineering, hydrology and (geo)stability. The collaboration between the Stadsbader Group, HUBER and Sweco guarantees high-quality project execution thanks to local roots on the one hand and process and technical expertise on the other. After submitting the approval documents at the end of 2023, the environmental permit for the Beringen site was granted after just over six months. The permit for the plant in Roeselare is also expected this year. This means that the engineering phase for this major project is as good as complete and the first work can start on site this year. 20 years, 82 plants and 1.8 million tonnes of sludge per year In the last 20 years, HUBER Belt Dryers have processed 1.8 million tonnes of sludge per year in 82 plants worldwide. With the appointment of HUBER as technology partner, the project partners can draw on decades of practical experience in the supply, installation and commissioning of sludge drying plants. HUBER has already gained regional experience with its drying technology in the Benelux region: one of the largest belt drying plants, probably the largest in the world, is currently being built at the customer HVC in Alkmaar. Aquafin – current sludge chain Aquafin is a Belgian company that was founded in 1990 by the Flemish government and is responsible for the inter-municipal infrastructure and treatment of domestic wastewater. Every year, it produces around 350,000 tonnes of dewatered sludge with an average dry residue of 27%. The disposal of this sludge is currently organised via three disposal routes: One third of the sludge is dried using residual heat and fossil fuels and then utilised externally in the cement industry (co-incineration). One third is dewatered and processed under autothermal conditions in the sewage sludge recycling plant in Bruges. The remaining third is also dewatered and thermally recycled together with industrial waste by an external company. Aquafin – new sludge chain From 2026, Aquafin will initially dry up to a third of the dewatered sludge using HUBER Belt Dryer technology as part of its climate and energy targets. This will be done using residual heat that would otherwise be lost. For this purpose, two largely analogue drying plants will be built in Roeselare and Beringen. The sewage sludge delivered by lorry from around 40 different sewage treatment plants is fed directly into the HUBER Belt Dryers by a crane system from the bunker via a downstream moving floor and thick sludge pumps. In the Beringen plant, a total of 84,446 tonnes of dewatered sewage sludge per year are dried from 27 % to 90 % DR at an inlet temperature of 110 °C. Three HUBER Belt Dryers BT 28 are used for this purpose. In the Roeselare plant, two HUBER Belt Dryers BT 22 are used to dry 36,000 t/a of dewatered sewage sludge from 27 % to 90 % DR at an inlet temperature of 90 °C. The bunker and dryer exhaust air are treated separately, with the dryer exhaust air undergoing a 4-stage cleaning process – with scrubbers, biofilters and downstream activated carbon filters. After drying, the sewage sludge is fed into a pellet press by screw conveyors and a bucket conveyor. The cooled pellets are then stored in dry material silos before being transported to Ghent. Construction of a mono-incineration plant in Ghent Aquafin will build a mono-incineration plant on the site of the steel company ArcelorMittal in the port of Ghent by 2026, in which the sewage sludge dried in Beringen and Roeselare will be utilised. ArcelorMittal will purchase 100% of the steam generated by the sludge treatment plant. For the steel company, this is an additional source of energy for its internal steam network, further reducing the use of fossil fuels. The direct purchasing of the entire steam production in combination with the focus on raw material recovery (phosphorus) gives the overall project considerable ecological added value. This new plant will be designed, built, financed and maintained until 2046 by the BESIX Indaver consortium. A prime example of sustainable resource management With its belt drying technology, HUBER is making a significant contribution to Aquafin's goal of no longer using fossil fuels by 2030 and becoming a climate-neutral company in the long term. In addition, waste heat is utilised directly at the point of origin and the dried sewage sludge is transported to the utilisation site as an energy source. The large-scale Aquafin project is therefore a transferable example of sustainable resource management.[...]

Also the fine screens will be installed at an angle of 60° as this improves hydraulics, enlarges the screen surface area and reduces the flow velocity between the screen bars. - Channel width: 3.2 m - Channel depth: 3.6 m - Maximum flow rate: 3.7 m³/s - Bar spacing: 3 mm Installation of six HUBER Wash Press WAP® HD 8 units including integration into the screenings transport system: - maximum throughput capacity per machine: 12 m³/h raw screenings - dewatering performance > 35% DS Installation of two longitudinal conveyors / collection conveyors – including distribution shaft with changeover switch conveyor 1 / conveyor 2 - Spiral diameter: 600 mm - Conveying length: 33.9 m each Installation of two horizontal screw conveyors for redundant feeding of the screenings loading presses The complete measurement & control technology and wiring Extensive modernisation of the Vienna wastewater screening plant: six HUBER Multi-Rake Bar Screen RakeMax® units with 8 mm and 3 mm bar spacing, six HUBER Wash Press WAP® 8 HD units and screenings conveying system. The Danube metropolis Vienna is world-famous for its New Year's Day concert that is performed by the Vienna Philharmonic Orchestra and broadcast worldwide every year and as native city of the "Waltz King" Johann Strauss and world musician Falco. But it was not so long ago that the heavy bomb damage to the sewer system during World War I and II was rehabilitated in 1950 so that the city of Vienna could start with planning the treatment of the city's wastewaters. At first, two small plants were built in the southern part of Vienna, the first of them went into service in 1951. In the sixties, when the planning phase for the Vienna main sewage treatment plant started, there had been plans to build an own plant for the districts Floridsdorf and Donaustadt on the other side of the Danube but these plans were abandoned. It was decided that the wastewater from "Transdanubia" should flow to the main sewage treatment plant through a 567 m long structure under the Danube. Simmering, the topographically deepest point of Vienna, was selected as location for the Vienna main sewage treatment plant. As one of the largest sewage treatment plants in Europe at that time, the plant was put into operation by Vienna's mayor Leopold Gratz in 1980. In 2005, the second biological treatment stage was put into operation to ensure the state-of-the-art treatment of the city's wastewaters and prevent that the Danube water quality is impaired. The Vienna main sewage treatment plant is presently laid out for 4.0 million PE60 and the maximum flow rate of 18 m³/s during storm conditions. In 2013, in the run-up to the widely noticed EOS project, ebswien hauptkläranlage Ges.m.b.H. and the engineering office commissioned by ebswien thought about how to significantly increase and optimize the screenings separation rate. In a number of meetings HUBER supported the planning office with advice and recommendations. Several technical proposals were developed but finally the HUBER RakeMax® variant turned out to become the most probable solution. Moreover, IFAT 2014 gave us the chance to convince the decision makers of ebswien by showing them our RakeMax® screen on our exhibition stand. There, they got to know HUBER as a competent future partner and supplier. The project could then be finalized at the beginning of 2015 and the order was placed with HUBER. Now, ebswien hauptkläranlage Ges.m.b.H. intends to modernize the existing sewage screening plant and add a fine screening plant in the eastern part of the grit trap building. The fine screening plant offers high-quality technology on a small footprint – possibly unique in Europe in this form. After all, one can read on every Vienna city limits sign: "Vienna is different“ – why should this not also apply to the Vienna's main sewage treatment plant? Test operation of the first tow coarse and fine screen lines was successfully finished meanwhile. Presently, the third line is being installed and will soon be put into operation. It is planned to complete the six new screen lines and hand them over to ebswien Hauptkläranlage Ges. m. b. H. by the end of 2016.
