[...]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.

[...]Automatically cleaned screen for solids retention in stormwater tanks and overflows Efficient solids separation Continuous automatic screen cleaning Maximum adaptability Ideal for combination with water retention elements Sturdy, low-maintenance stainless steel design During and after storm events large amounts of debris are discharged to streams, rivers and lakes through storm water overflows of combined and sanitary sewer systems. Frequently, even the installation of scum boards is insufficient to prevent such pollution. The polluting items, such as sanitary products, toilet paper, faeces, plastic foils, etc. are not only unsightly but also responsible for considerable cleaning and/or disposal costs. On the basis of the DWA sheet A 128 (an instruction issued by an association dealing with wastewater treatment) efforts to fundamentally improve the protection of waters in this sector have been increased. Particularly endangered receiving water courses and nature preservation areas require more extensive measures concerning the treatment of stormwater. Design and Function The HUBER Storm Screen ROTAMAT® RoK2 is the ideal solution for this task, whether for new structures or refurbishment. The screen belongs to a group of fine screens designed for high flow rates at an extremely low hydraulic resistance. Two-dimensional screening guarantees a very high solids retention combined with automatic, gentle cleaning of the perforated plate. HUBER Storm Screen ROTAMAT® RoK2 screens are horizontally installed at the upstream side of overflow weirs. A screw flight is mounted on a half cylinder of perforated plate. As the stormwater flows through the horizontal perforated half-pipe of the screen trough the solids are retained. A screw, with a brush attached on its flights, rotates within the semi-circular screen trough. It cleans the screen and pushes the separated solids gently towards the lateral discharge. The screenings remain on the polluted water side of the screen from where they are taken along with the wastewater flow. During storm conditions the screen is automatically started and then works fully automatically. The HUBER Storm Screen ROTAMAT® RoK2 can be flexibly installed on the left or right side of the weir overflow to optimally meet different local hydraulic conditions. Even if the flow rate is low, the oncoming flow approaches the full screen basket length and the screenings are removed gently without blockage so that a high separation performance is achieved and the headloss minimized mechanically. The Applications HUBER Storm Screen ROTAMAT® RoK2 units can be used for a variety of applications in the combined sewage sector. To avoid another point of maintenance it is generally not intended to remove screenings from the structure. Instead, the screenings remain within the sewer or tank and are introduced into the wastewater treatment plant after the storm event. The Benefits of the HUBER Storm Screen ROTAMAT® RoK2 The screen is installed in front of the weir overflow. This design results in the following favourable benefits: Optimal solids retention by means of two-dimensional screening (perforated plate) Screenings remain on the polluted water side No downstream impact on the screen efficiency For problem-free retrofitting into existing structures The perfect solution for discharges with limited upstream head possibilities Optional emergency overflow[...]

[...]Efficient distribution of screenings Temporary storage of screenings Optimal distribution into containers Particularly suitable after a HUBER Wash Press WAP® The HUBER KT tipping trough is the ideal solution for evenly distributing screenings from wash presses. Designed for maximum reliability and flexibility, the HUBER Tipping Trough KT ensures optimised transfer of screenings to downstream containers. Design and Function The HUBER KT tipping trough uses a level sensor to detect incoming screenings and start the distribution process. The automated rotation of the trough allows the screenings to be discharged in one or both directions. This increases the bulk density of the screenings in the container, making them more compact so that the container’s capacity is used more efficiently. Manual distribution of screenings in the container by operating personnel is therefore unnecessary. Versatile and adaptable Thanks to its variable tipping length of 2 to 6 metres, the HUBER Tipping Trough KT can be tailored precisely to the specific requirements of your plant. The diameter of the trough is matched to the upstream machine, for which we recommend the use of a HUBER Wash Press WAP®. The robust construction ensures a long service life, even under demanding operating conditions. Optimal integration The HUBER Tipping Trough KT is specially designed for use with HUBER Wash Presses. It receives the cleaned and dewatered screenings from the press and distributes them efficiently into a container. Its easy integration into existing HUBER systems makes it the preferred choice for municipal and industrial wastewater treatment plants. Advantages of the HUBER Tipping Trough KT Flexible tipping length: 2 - 6 m for individual plant configurations Customised trough diameter: DN450 - DN600 for optimal connection to the upstream machine Robust design: for long-lasting, low-maintenance operation Efficient distribution: optimises material flow after screenings treatment Seamless system integration: ideally designed for use with HUBER Wash Presses[...]

[...]Wastewater fine screening Screenings treatment Grit separation Grit classification Requirements for a complete mechanical wastewater treatment plant Manually operated screens and grit traps are no longer sufficient even for small wastewater treatment plants. The increased demands on biological treatment make it necessary to improve the separation performance of mechanical treatment. Solid material has to be separated as far as possible and removed. Screens with automatic cleaning and integrated discharge are now required. Screenings treatment, such as washing of faecal matter, dewatering and compaction, is required more and more often for economic and hygienic reasons. Reliable state-of-the-art grit separation and automatic grit discharge are needed. Our HUBER Coanda Complete Plant ROTAMAT® Ro5 C offers all these mechanical wastewater treatment steps for small sewage treatment plants in one machine. Design and function A container-mounted ROTAMAT® Micro Strainer removes solid material from the wastewater depending on its bar spacing (e.g. e = 2 mm). Screenings are removed and transported by a screw conveyor. Inside the closed rising pipe, screenings are dewatered and compacted by an integrated press. Subsequently, they are discharged into a container. The cleaned wastewater flows by gravity into a COANDA circular grit trap. As the COANDA Tulip is fed through a vortex chamber, the wastewater flow gets a tangential in addition to a radial flow direction. Air is sucked into the vortex and mixed with the waste water flow. The combination of three effects, namely the COANDA effect, the tea-cup effect and the air intake, guarantee that the organic components are kept on the surface and discharged over a weir while the grit settles in the lower trough area. The separated grit is removed through a classifying screw, statically dewatered and discharged into a container. Benefits of the HUBER COANDA compact unit Complete mechanical preliminary treatment combined in a single unit Maximum throughput up to 25 l/s (90 m3/h) Small space requirements Integrated dewatering and compaction of the screenings; option of screenings washing High grit removal efficiency Completely made of stainless steel (also the augers) Option of frost-proof design down to -25° C Grit classifying screw supported on both ends Encapsulated, odour-free plant[...]

[...]Reduced disposal costs Less than 3 % organic content Very high solids content of > 90 % Easy to retrofit after existing grit classifiers Conventional grit separation Conventional grit classifiers separate virtually all solids contained in the grit trap effluent. This classified and partly dewatered grit is usually more or less contaminated with organic particles. Subsequent grit washing The classified grit is therefore further treated in the subsequent grit washer where the organics are separated from the mineral particles. Design and Function Due to a defined introduction of upwardly directed service water the grit situated in the lower part of the HUBER Grit Washer RoSF4 T will be fluidised in flow, i.e. a grit fluidised bed is generated. Within this fluidized bed the lighter organic particles are separated from the dense grit particles, independent of the particle size. This process is supported by the central stirrer keeping the particles in motion. After removal of the organic material the clean grit is removed through a classifying screw, statically dewatered and discharged into a container. The removed organics are automatically discharged with the introduced wash water. The Benefits of the HUBER Grit Washer RoSF4 T Reduced disposal costs Dewatering of washed grit to approx. 90 % dry residue Organic content reduction to < 3% loss on ignition Throughput capacity up to 3.0 m³ solids per hour Low investment costs For easy installation subsequent to grit classifiers, complete plants, circular grit traps Grit removal screw supported on both ends for long life High corrosion protection[...]
