[...]Reliable separation of fine suspended solids (sludge flocs, microplastics) Ideal for phosphorus removal (flocculation filtration) Reliable retention of powdered activated carbon (PAC) for removal of trace substances Efficient prefiltration to protect ozonation and GAC adsorption systems for trace substance removal A pile cloth is a fabric in which pile yarns are firmly bound onto a supporting mesh, creating a three-dimensional structure. The solids are retained by this pile cloth, while the cleaned water enters the interior of the filtration system and is led via a weir to the next stage or into the receiving water. Materials of HUBER Pile Cloth Media Filter RotaFilt®: All metallic parts made of stainless steel (stainless steel parts acid treated in a pickling bath) Disc support segments made of high-quality plastic with optimised free surface; uncomplicated replacement of segments and pile cloth media bags The right type of pile cloth for every application Design and Function The HUBER Pile Cloth Media Filter Rotafilt® consists of several rotatably arranged, disc-shaped filter elements. These are installed vertically and fitted with special filter bags made of innovative pile cloth. The pile cloth has a multi-dimensional structure and consists of a filter-active pile cloth layer and a supporting mesh. The wastewater that enters the filter chamber flows continuously through the individual filter discs from the outside to the inside. Particulate matter is reliably retained in the pile cloth structure. Due to the retention of solids, the filter resistance increases and the difference between the water levels on the wastewater and clear water side rises. At a certain pressure loss, the gradual cleaning of the filter discs begins. During this process, retained solids are reliably and effectively removed from the rotating filter elements via suction bars. The round filter discs ensure that no dead zones are created during the cleaning process. In order to prevent the basin from silting up, the settled sludge at the bottom of the basin is sucked out at regular intervals. Technical data: Available disc diameters: 2,200 mm and 2,700 mm, RotaFilt® 2,200 is available as a basin or tank version. All metallic parts made of stainless steel, acid treated in a pickling bath. Disc support segments made of high-quality plastic with optimised free surface; uncomplicated replacement of segments and pile cloth media bags. The right type of pile cloth media for every application. Feeding either by gravity or by pump. The benefits of the HUBER Pile Cloth Media Filter RotaFilt® Optionally one or more suction pumps.

[...]Baden-Württemberg, Germany A fourth treatment stage is currently being built at the sewage treatment works in Schwäbisch Hall, Markgröningen-Talhausen, Vörbach-Pfalzgrafenweiler and Meßkirch in Baden-Württemberg. These treatment works have opted for the GAC (German: GAK) process, which uses granulated activated carbon for adsorption. Upstream of the trace substance removal stages, there is a multi-stream pre-filtration system at each site, all of which have been equipped with the new HUBER Pile Cloth Media Filter RotaFilt®. These reliably protect the subsequent GAC‑adsorption process from dirt and contaminants, thereby ensuring stable and low-maintenance plant operation. In Vörbach-Pfalzgrafenweiler, twelve HUBER Activated Carbon Filter CONTIFLOW® GAK units are used as the GAC stage. Trace substance removal and phosphorus removal At the Eglosheim-Ludwigsburg wastewater treatment plant, powdered activated carbon is dosed directly into the biological stage to remove trace substances. Here, cloth filtration acts as a conventional final filtration stage and ensures that no loaded activated carbon particles from the secondary clarifier enter the receiving watercourse. In all five projects, cloth filtration can also be operated in combination with coagulant dosing as flocculation filtration, should the most thorough possible removal of phosphorus be required. Outlook and project status All five plants are still under construction at present. The fourth-stage treatment facilities in Schwäbisch Hall and Eglosheim-Ludwigsburg are expected to be operational by 2026. The other projects are expected to be operational in 2027.[...]

[...]Machines and plants for wastewater treatment are usually installed as permanent installations in structures and buildings due to process engineering necessities. This usually requires extensive preliminary investigations, studies, concepts, planning, authorisations, tenders and construction phases involving and coordinating a wide range of different trades. This is usually a lengthy, costly and capital-intensive process. Systems that are not permanently installed but temporarily rented are the alternative. Their short-term availability is also particularly advantageous, which is why rental systems can also be selected for short-term breakdowns, construction work or to bridge a gap. With fixed monthly payments, this model offers many industries an interesting option to the large amount of capital tied up in permanent installations. Such rental systems have been and continue to be in demand, particularly from the industrial sector, but also from municipal plant operators, and we are already supplying them with machines from the HUBER pilot plant and used machine stock. Due to the steady increase in enquiries, HUBER is now starting the targeted expansion of the business for rental plants, including the necessary services. The following plant types are currently available (each fully equipped in containerised and skid-mounted design, with control system and necessary accessories): HUBER Dissolved Air Flotation HDF plants up to 80 m³/h throughput, for pre- and secondary treatment of municipal wastewater (reduction of filterable solids, grease and COD) HUBER Screw Press Q-PRESS ® units for dewatering industrial and municipal sludge and residues Ultra-fine screens with up to 80 µm separation efficiency In the medium term, the existing machinery will be expanded to include further technologies and plants, each in mobile design.

[...]Prevents clogging and tressing in the pumping station Compact unit, easy to fit into confined spaces Dewatering and compaction of screenings Optional frost-protected unit for outdoor operation Sturdy, low-maintenance stainless steel design Pumps and lifting units are used where wastewater needs to be lifted to a higher level so that it can be passed further on by gravity. However, the solids contained within the wastewater frequently lead to pump failure. Labour-intensive manual cleaning is required to restore the function of the units, or they may need to be replaced, both resulting in high long-term costs. Reliable solids removal is therefore the only alternative to maintain the operating stability of the pumps. Design and Function The HUBER Pumping Stations Screen ROTAMAT® RoK4 is the ideal solution for this task, whether for new structures or refurbishment. Contrary to conventional screening systems which require manual cleaning, the screen surface of the HUBER Pumping Stations Screen ROTAMAT® RoK4 is cleaned automatically. The screen Vertically lifts the screenings, and dewaters and compacts them at the same time. The compacted screenings are discharged into a container or endless bagger for further disposal thus eliminating odour nuisance and pump failure due to clogging. The screen consists of a vertical perforated screen basket and a shafted auger in a vertical tube. The wastewater flows through an inflow connection and a chamber into the screen basket. Within the screen basket the flights of the screw are equipped with wear-resistant brushes for effective cleaning of the screen. As the screenings are gradually elevated by the auger, they are dewatered. The compacted screenings are discharged into a container or endless bagger thus eliminating odour nuisance. The screened wastewater flows off by gravity or is pumped to a higher level. The filtrate drains through a hose back into the inlet chamber. The top of the inflow chamber is open and serves as an emergency bypass so that the machine can be submerged without problems, e.g. in case of a power failure. The integrated bottom step prevents back-flooding into the sewer system and thus undesired deposits in the incoming sewer. The benefits of HUBER Pumping Stations Screen ROTAMAT® RoK4 Automatic screening, lifting and compaction in a single compact unit Optimal solids retention by means of two-dimensional screening (perforated plate) Prevent clogging and tressing in pump stations and manholes Integrated bottom step to prevent deposits in the incoming sewer Easy to install into existing structures Availability of completely submerging the screen[...]

[...]For the protection of our most valuable resource – water Sustainability is of greatest importance in the field of water supply when investments are planned to modernise and refurbish elevated reservoirs, wells and pressure increasing plants. HUBER has convincing solutions to offer, one of them is the technically mature and high-quality safety door RC3. Many of this type of door have meanwhile been installed on a number of sites. Customers appreciate particularly its functionality and attractive appearance. In most cases, the doors can be installed without problems by the customers' qualified personnel themselves. Some plant operators have developed their own standards and design versions of HUBER RC3 doors. Leibnitzerfeld Wasserversorgung GmbH for example has equipped the exterior surfaces of all its HUBER doors with a steel sheet panel to protect them against sunlight. Where possible, a stainless steel frame is added to the RC3 safety doors to cover the wall. Also the process of project handling has been recognised as positive, including the field measures taken on site and the questionnaires for doors that have been worked out by the HUBER field service together with the responsible water masters. HUBER RC3 safety doors not only fit perfectly into the overall picture of each individual smaller or larger project, they significantly improve the protection of our most important resource, our water.

[...]With the HUBER RoDisc® Rotary Mesh Screen we have risen to the challenge of increased requirements on future wastewater treatment. New technical developments combined with innovative manufacturing technology ensure the HUBER RoDisc® Rotary Mesh Screen is ahead of future requirements in wastewater treatment. Maximum corrosion protection is an indispensable prerequisite in wastewater treatment. HUBER has used a pickling bath for many years already to achieve the optimum passivation of stainless steel surfaces. Increasing requirements (chemicals in filter inlet) and increased use of the Disc Filter for filtration in coastal areas (salt water) made it necessary to go new ways. HUBER has therefore developed a new type of discs with a high-quality polypropylene base frame. In addition to increased corrosion resistance, this new type of discs has other positive effects that open up new market chances: Due to their significantly reduced weight the maximum possible number of discs for one machine can be increased from 20 to 30. The resulting 50% increase in throughput per machine makes the micro screen affordable also for the operators of big treatment plants who want to upgrade their plants. The new design also permits easy replacement of the filter mesh (stainless steel or optionally polyester). The filter mesh is attached to the flat frame and can be replaced without the need to dismount the discs. The method of how the mesh is fixed to the flat frame should be pointed out especially. In contrast to other common micro screening technologies on the market, the mesh of the RoDisc® screen is not glued onto the frame but attached and embedded by means of a special patented thermal process. At the point of attachment the mesh is completely sheathed by the plastic flat frame material so that a form-locked connection and thus 100% protection of the attachment point against external influences is achieved. Reliable and permanent mesh fixture is guaranteed independent of the use of chemicals for the reduction of phosphate or endocrine substances. The innovative manufacturing technology applied with the HUBER RoDisc® screen sets a milestone in disc filter technology.[...]

[...]With integrated screenings press With integrated screenings washing More than 2000 installations worldwide Available with wedge wire ("Ro2"), perforated plate ("RPPS") and folded perforated plate ("STAR") screen basket Wastewater treatment plants and industrial applications for process and wastewater treatment require mechanical treatment as a first treatment step to remove as much as possible of the floating, settling and suspended material. The aim is to reliabily achieve the maximum separation efficiency under the prevailing hydraulic conditions. The HUBER Rotary Drum Fine Screen ROTAMAT® operation is based upon a unique system that allows combination of screening, washing, transport, compaction and dewatering in a single unit. Depending on the screen bar spacing (0.5 - 6 mm) or perforation (1 - 6 mm) and screen size (screen basket diameter of up to 3,000 mm), the throughput can be individually adjusted to specific site requirements. The HUBER Rotary Drum Fine Screen ROTAMAT® is completely made of stainless steel and acid treated in a pickling bath. Design and Function The HUBER Rotary Drum Fine Screen ROTAMAT® operation is based upon a unique system that allows combination of screening, washing, transport, compaction and dewatering in a single unit. Depending on the screen bar spacing (0.5 - 6 mm) or perforation (1 - 6 mm) and screen size (screen basket diameter of up to 3000 mm), the throughput can be individually adjusted to specific site requirements. The HUBER Rotary Drum Fine Screen ROTAMAT® is completely made of stainless steel and acid treated in a pickling bath. HUBER Rotary Drum Fine Screen ROTAMAT® units are either installed directly into the channels, or are supplied as tank-mounted units, with an inclination of 35°. The wastewater flows into the open end of the inclined screen basket and then through the screen. Floating and suspended materials are retained by the screen basket. Blinding of the screen surface generates an additional filtering effect so that solids can be retained that are smaller than the bar spacing or perforation. The basket starts to rotate when a certain upstream water level is exceeded due to screen surface blinding. The rotating screen drum lifts the screenings and drops them into the centrally arranged trough. Screenings removal from the drum is supported by a scraper brush and a spray nozzle bar. A screw conveyor in the trough rotates with the drum and transports the screenings through a closed and inclined pipe. The conveying screw transports, dewaters and compacts the screenings, without any odour nuisance, and discharges them into the customer‘s container or a subsequent conveying unit. Additional Model Variants and Options HUBER Rotary Drum Fine Screen ROTAMAT® PRO The special design of the HUBER Rotary Drum Fine Screen ROTAMAT® PRO series isolates the water level in the trough from the water levels upstream and downstream of the screen. This is achieved with a closed system below the perforated plate of the trough. The liquid phase is removed from the closed system by a suction pump which pumps the flow back to upstream of the machine. The solids are washed, compacted and discharged by a conveying screw. This operation method permits continuous screen operation with a constant water level upstream of the machine. Continuous system operation significantly increases throughput capacity. The PRO system can even be reliably applied with high downstream water levels and is especially suitable for pump applications. As backup of water into the trough is impossible, screenings discharge via the removal screw can reliably be ensured. It is easy to retrofit into any type of HUBER Rotary Drum Fine Screen ROTAMAT®. HUBER Perforated Plate Screen ROTAMAT® STAR The HUBER Perforated Plate Screen ROTAMAT® STAR is especially designed for fine apertures and for large wastewater volumes in a gravity line with low headloss. Its design is based on the well-proven ROTAMAT® principle: screenings separation, washing, transport, and compaction in one unit. To improve screen throughput capacity, the RPPS Star screen has a star-shaped screen basket with a zigzag folded surface. The star-shaped folded plate of the HUBER Perforated Plate Screen ROTAMAT® STAR provides an increased free screen surface and an approximately 30 % increase in throughput capacity with the same nominal diameter. The STAR design combines the benefits of maximum free screen surface and very high separation efficiency. This efficiency-improving innovative development permits for optimal and economical system dimensioning, it is space-saving and reduces civil costs. Installation is suitable into existing channels or for tank installation. HUBER Perforated Plate Screen ROTAMAT® STAR units are preferably used with perforations of 1 / 1.5 / 2 mm for installation on municipal and industrial wastewater treatment plants. The screens are also applied to protect downstream membrane systems by removal of hair and fibres. They can be installed in the mechanical treatment stage or downstream of grit traps. Special PRO design screens are available for applications where an additional increase in throughput capacity is required. Integrated Screenings Washing System IRGA To optimise the treatment process an integrated screenings washing system IRGA can be provided and also easy retrofitted. It improves the carbon/nitrogen ratio of the pretreated wastewater. In addition, the IRGA reduces the costs of screenings disposal to an optimal cost/performance ratio. The HUBER ROTAMAT® principle allows for integration of the screenings washing system directly in the trough and/or the lower end of the rising pipe. As the soluble matter is separated from the inert material, faeces are virtually completely washed out which leads to a significant weight reduction by approx. 50 % and improved operating and hygienic conditions. The dewatering performance of up to 40 % DS can be increased to more than 45 % DS by adding a high pressure unit (HP) to the integrated screenings washing system IRGA. This combination guarantees the maximum dewatering performance and reduces disposal and operating costs. Benefits of the HUBER Rotary Drum Fine Screen ROTAMAT® Ro2 / RPPS / STAR Low headloss – High separation efficiency: Due to the drum‘s shape and 35° installation the screen area is much larger than that of a vertical or steeply inclined screen, which results in a low headloss, high separation efficiency and maximum throughput. No by-passing: The entire flow enters the screen drum through its open front end and can only leave the drum through its screen area. This prevents plant overflow and guarantees that the screenings are always retained within the screen drum. Several functions combined in one system: The ROTAMAT® Screens perform the functions of screenings removal, transport, washing, dewatering and compaction in a single space-saving unit. An additional bagging unit guarantees operation of the entire system without odour nuisance. Outdoor installation: For frost-proof outdoor installation, the HUBER Rotary Drum Fine Screen ROTAMAT® can be supplied with a heating wire and thermal insulation. Completely made of stainless steel: The machine is completely made of stainless steel and pickled in an acid bath which eliminates corrosion and thus reduces maintenance. Retrofitting: The design of the ROTAMAT® Screens allows for later modification so that the systems can be adapted to changing requirements. The heating and/or integrated screenings washing can be retrofitted. The bar spacing can also be reduced to meet more stringent requirements. Low maintenance: No lubrication. Regular checking and visual inspection are sufficient.[...]
