[...]Increased separation efficiency through flow deflection in the bar rack Optimal hydraulic utilization of existing channels Unsusceptible to grit, gravel and stones The HUBER Multi-Rake Bar Screen RakeMax® CF is perfectly suited to serve both municipal or industrial wastewater, and process water screening. Due to its different design options the RakeMax® CF covers a very wide range of applications, allowing us to respond to the individual needs of our customers and to specific constructional and hydraulic site conditions. Design and Function The HUBER RakeMax® CF features a U-shaped stationary bar rack installed between two screen frames, positioned parallel to the wastewater flow direction. As the wastewater flows into the open front side of the screen and exits through both the left and right bar racks, solids are captured on the inner surface of the U-shaped rack. The accumulation of solids on the bar rack gradually clogs its surface, impacting the water level in the channel. To address this, cleaning of the screen bars is initiated at a defined water level upstream of the screen. The RakeMax® CF uses cleaning elements attached to a chain system to perform this function. The discharge capacity is adjustable to meet specific requirements, as the number of screening elements on the chain system can be modified. The RakeMax® CF screen is designed with a very low height above the floor, and even in deep channels, its installation height depends solely on the downstream screenings transport or washing system. If the screen encounters a blockage, an electric control system ensures reliable protection by preventing damage from overload. At the end of the bar rack cleaning cycle, the rake is thoroughly cleaned by a pivoted comb, which effectively discharges the collected screenings into a downstream transport or disposal unit. The drive unit, which is easy to access and maintain, is installed above the channel for convenient servicing. The benefits of the HUBER Multi-Rake Bar Screen RakeMax® CF Increased separation efficiency through flow deflection in the bar rack Integrated emergency overflow Optimal hydraulic utilization of existing channels Very low head loss – high separation efficiency The precise meshing of the cleaning rakes with the bar rack ensures high operational reliability Screen installation possible without a bottom step Compact design with a low installation height above ground level Completely odor-encased screen with easy to remove covers Not hindered by gravel or grit Easy-to-retrofit into existing channels, installation without channel recesses possible The screen is a sturdy self-supporting stainless steel construction and therefore can easily be lifted out of the channel Simple and easy-to-access chain tensioning unit All machine components in contact with the medium are made of stainless steel and acid treated in a pickling bath (except chains, pinions, drives and bearings). The chains and chain wheels are optionally available in stainless steel High screenings discharge capacity through a variable number of screen rakes Automatic scraper mechanism, no service water required[...]

[...]Very high screenings discharge capacity Low head loss Low installation height above ground level even in deep channels Control-independent safety system The HUBER Multi-Rake Bar Screen RakeMax® is perfectly suited to serve both municipal or industrial wastewater, and process water screening. The cleaning elements, attached to the chain system, can easily be adjusted to different requirements. As the cleaning elements can be variably adapted, the screenings removal capacity is then adjustable. This is especially favorable for high solids loads. The cleaning elements, consisting of the rake and comb plate, are screwed and thus independently replaceable. Due to its versatile design options the RakeMax® covers a very wide range of applications, allowing us to respond to the unique needs of our customers and to specific constructional and hydraulic site conditions. Function of the HUBER Multi-Rake Bar Screen RakeMax® The RakeMax® screen’s specific design ensures a very low height above the floor, even for deep channels, as its height depends only on the installation height of the downstream screenings transport or washing system. Both ends of the cleaning elements are securely connected to drive chains, which are powered by sprockets on a common shaft and a flange-mounted gear motor. Additionally, the precise meshing of the cleaning rakes with the bar rack guarantees high operational reliability. An electro-mechanical overload protection system (spring assembly with deflection monitoring) reliably ensures that the process is interrupted when the preset overload is reached, or in case of a blockage. Model Variants and Options RakeMax® J The RakeMax® J screen is a modified version of the proven HUBER RakeMax® screen. In contrast to the standard RakeMax® design version, the RakeMax® J screen does not have straight bars, the screen bars are bent in the bottom section, i.e. curved towards the sewer base. It is also this special form of the screen bars which gives the screen its name as the letter ‚J‘ has approximately the same shape as the curved screen bars. The screen rake moves along the curvature of the screen bars and describes a segment of a circle in this section. The flat inclination angle of the screen bars in the sewer base section increases the cross-sectional flow area of the screen with the result of reduced hydraulic losses and a reduced flow velocity in the gaps between the screen bars. RakeMax® HF The RakeMax® HF effectively combines the proven advantages of the RakeMax® with the benefits of a screen featuring a bar rack installed at a minimal inclination. The RakeMax® HF has a L-shaped design with two different screen sections: The flat bottom section provides a large screening surface and favorable hydraulic conditions, the steep conveying section ensures screening on a small footprint. Due to the extremely flat installation of the bar rack of 30° the screen section through which the flow passes is always double the depth of the approaching flow. Material removal from the screen starts virtually right at the bar rack mounted flat to the channel bottom so that any accumulation of unwanted material is eliminated. Optimal flow conditions and a large effective bar rack surface guarantee high hydraulic throughput capacity. RakeMax® Hybrid The special feature of this type of screen is a bar rack that is manufactured from highly wear-resistant fibreplastic composite. By adding materials like glass fibre or resins for example the profile bars are made suitable for applications with high mechanical loads and excel for their very high stability, deformation resistance and resistance to wear. Due to their high breaking elongation and elastic energy absorption the profiles retain their shape even under mechanical load, are highly flexible and return to their original shape. They also excel with a very high production precision, size accuracy and form stability so that even smaller bar spacings can reliably be maintained. Another advantage of the RakeMax® Hybrid screen are the individually replaceable screen bars for quick and safe handling without the need for welding work. Safety Vision The innovative HUBER Detection System Safety Vision enables the screen to "see" the screenings and reliably identify potentially critical contaminants. This effective protection mechanism reliably prevents damage to the screen or the downstream equipment, which not only increases the availability of the machines involved, but also improves the operational safety of the entire plant technology. In addition, the adaptive operation based on event detection means that the machine can always be optimally utilized and the running time of downstream machines can be optimized according to the actual necessary demand. The benefits of the HUBER Multi-Rake Bar Screen RakeMax® Very low head loss – high separation efficiency Defined meshing of the cleaning rakes with the bar rack ensures a high operating reliability. Screen installation possible without a bottom step Compact design with a low installation height above ground level Completely odor-encased screen with easy to remove covers Easy-to-retro fit into existing channels, installation without channel recesses possible The screen consists of a self-supporting folded stainless steel profile so that it can easily be lifted out of the channel.

[...]Prevents clogging of pumps in the pumping station Compact design for easy installation in confined spaces Dewatering and compaction of screenings Optional frost-protected unit for outdoor operation Durable, low-maintenance stainless steel construction Pumps are essential when wastewater needs to be elevated to a higher level for downstream gravity flow. However, the solids within the wastewater often cause pump blockages, leading to costly pump failures. Restoring functionality typically requires labor-intensive manual cleaning or replacement of the units, resulting in high long-term costs. Reliable solids removal is, therefore, critical to ensuring the stable operation of the pumps. Design and Function The HUBER Pumping Stations Screen ROTAMAT® RoK4 is the ideal solution for preventing pump failure and clogging, whether for new installations or refurbishments. Unlike conventional screening systems that require manual cleaning, the RoK4 features an automatic self-cleaning screen surface. The system lifts, dewaters, and compacts the screenings simultaneously. The compacted screenings are then discharged into a container or endless bagger for disposal, effectively eliminating odors. The screen consists of a vertical perforated screen basket and a shafted auger within a vertical tube. Wastewater flows through an inflow connection and chamber into the screen basket. Inside the basket, the auger's flights are equipped with wear-resistant brushes to ensure thorough cleaning of the screen. As the screenings are elevated by the auger, they are progressively dewatered. The compacted screenings are then discharged into a container or bagger, minimizing odor. The pressate drains through a hose back into the inlet chamber. Meanwhile, the screened wastewater flows off by gravity or is pumped to a higher level. The top of the inflow chamber is open, serving as an emergency bypass to allow the system to function even if submerged, such as in the event of a power failure. Additionally, an integrated bottom step prevents back-flooding into the sewer system. Benefits of the HUBER Pumping Stations Screen ROTAMAT® RoK4 Automatic screening, lifting, and compaction in a single, compact unit Optimal solids retention through two-dimensional screening (perforated plate) Prevents clogging and jamming in pump stations and manholes Integrated bottom step to prevent deposits in the incoming sewer Easy installation into existing structures for seamless integration[...]

[...]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 adequate, even for small wastewater treatment plants. As the demands on biological treatment continue to rise, it has become essential to enhance the separation performance of mechanical pre-treatment processes. Solid inorganic material must be separated effectively and removed efficiently. Screens with automatic cleaning and integrated discharge systems are now essential to meet these requirements. Screenings treatment, including the washing of organic matter, dewatering, and compaction, is becoming increasingly necessary for both economic and hygienic reasons. Reliable, state-of-the-art grit separation and automatic grit discharge are essential for efficient wastewater treatment and optimal plant performance. 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 The HUBER COANDA Compact Unit is a robust, space-efficient solution for mechanical preliminary wastewater treatment, delivering reliability, efficiency, and durability in a single integrated package. A tank mounted ROTAMAT® Micro Strainer effectively removes solid material from wastewater based on its perforation size (e.g., 3 or 6 mm). The screenings are collected and transported by a screw conveyor. Inside the enclosed rising pipe, the screenings are washed, dewatered and compacted by an integrated press before being discharged into a bagger and or container. The cleaned wastewater flows by gravity into a COANDA circular grit trap. As the COANDA Tulip enters a vortex chamber, the wastewater flow is given both a tangential and radial flow direction. Air is drawn into the vortex, where it is mixed with the wastewater, enhancing the separation of grit and other solids. The combination of three effects — the COANDA effect, the tea-cup effect, and the air intake—ensures effective separation. The organic components are kept on the surface and discharged over a weir, while the grit settles in the lower trough area for removal. This process optimizes the separation of solids, improving overall treatment efficiency. The separated grit is removed through a classifying screw, statically dewatered and discharged into a container. Benefits of the HUBER COANDA Compact Unit Integrated Mechanical Treatment : Combines complete preliminary wastewater treatment in a single compact system, streamlining processes and saving space.

[...]Well-Proven Mechanical Preliminary Treatment Equipment High Grit Separation Efficiency: Delivers excellent grit separation performance, ensuring high-quality wastewater treatment. Large Scum Separator: Features an automatic grease removal system for effective scum separation. Optional Grit Washing: Offers the flexibility of integrated grit washing for enhanced waste material management. Innovative Design: The unique HUBER Complete Plant Hydro Duct ROTAMAT® Ro5 HD combines the advantages of both aerated and unaerated grit traps, providing high performance in a compact footprint. This innovative grit trap ensures efficient separation while minimizing space requirements. Design and Function The wastewater first passes through an inlet screen that retains, washes, compacts, and dewaters the solids within the flow. The screened wastewater then flows at a right angle into an aerated grit trap tank, where it generates a spiral flow. Integrated air tubes enhance the spiral flow, keeping organic particles in suspension. At the same time, grease and similar substances float to the surface within the grit trap. Next, the flow enters a second unaerated upflow grit chamber, which includes an integral Hydro Duct that ensures a directed flow from the bottom with a positive and uniform upflow distribution. The flow velocity in this chamber is reduced, allowing very fine grit to settle at the bottom, while fats, oil and grease (FOG) rises to the surface, where it is automatically removed by a reliable paddle system. The particles separated in both chambers are removed by classifying screws or grit pumps and are simultaneously dewatered or washed in a grit washer before being discharged into a dumpster. As an option, the separated grit trap material can be washed in the Complete Plant. In this case, a horizontal grit conveyor transports the separated grit directly to a grit washer integrated at the plant's outlet. To ensure efficient separation, upwardly directed service water fluidizes the grit in the lower part of the grit washer, enabling lighter organic particles to separate from the dense grit. This separation is aided by a stirrer. After the organic material is removed, the clean grit is automatically discharged via a classifying screw, statically dewatered, and sent to a container. The Benefits of the HUBER Complete Plant Hydro Duct ROTAMAT® Ro5 HD Fully integrated screenings separation, c ombines screenings separation, washing, and dewatering in one system Exceptional Grit Separation: Achieves up to 95% grit separation for particles as small as 200 micron (independently verified).

[...]The HUBER Wash Press WAP® – A cost-effective method of screenings washing! Screenings Wash Press for any application Dewatering performance up to 45 % DS Weight reduction up to 75 % Throughput up to 52 ft. / 12 m³/h Automatic wear detection Completely made of stainless steel Design and Function The screenings to be treated are directly discharged from a screen or conveyor (e.g. a screw conveyor) into the feed trough of the Wash Press. A robust conveying and compacting screw then transports the screenings into the wash zone. Here, the screenings are subjected to intense and directed turbulence generated by the automatic introduction of wash water (service water), ensuring effective washing and dewatering of the solids. The turbulence created in the wash zone ensures the perfect separation of organic particles, resulting in highly effective screenings washing. Both the washing intensity and the number of wash cycles are individually adjustable, allowing for optimal customization based on specific treatment needs. The washed screenings are then conveyed through the rising pipe to the press zone, where they are dewatered by the compacting screw. This process effectively presses the screenings to achieve a dry solids (DS) content of 35-45%, significantly reducing their volume and weight. The wash water generated during screenings compaction, which is rich in carbon, is discharged back into the wastewater stream. Additionally, the system features automatic cleaning of the wash water collecting tank beneath the machine, ensuring continuous operation and preventing the buildup of contaminants. The washed and compacted screenings are finally transported through the conical discharge pipe into a skip for easy disposal. To optimize maintenance, machine sizes 2-12 are equipped with wear detection for the compacting screw in the press zone. This system automatically identifies the ideal time for auger maintenance, helping to prevent unexpected breakdowns and ensuring efficient operation. The HUBER Launder Channel HLC Feed System for Screenings Wash Presses The HUBER Launder Channel operates either discontinuously in a batch mode or continuously, depending on the system's configuration. The screenings to be treated are deposited into the launder channel from one or more screens. Wastewater or service water is then used to flush the screenings into the wash press. This flushing water also serves as wash water for the screenings washing process, ensuring effective cleaning while minimizing the use of additional resources. HUBER Launder Channel HLC systems are highly customizable to meet specific customer requirements. To ensure maximum operating reliability, the control system can be designed to incorporate redundant wash press systems. This setup allows for the individual units to be operated as needed, with valve control managing the flow to each unit, ensuring continuous and efficient operation even in the event of system maintenance or failure.

Design and Function The HUBER Basket Screen CageLift prevents such blockage, the entanglement of debris and damage of equipment as it removes the material. The screen can be installed in a manhole prior to pumps, the size depending on the inflow rate and depth. The sturdy, stable basket screen with bar spacing from 20mm to 80mm retains the floating debris at the sewer outlet. The screen bottom plate is perforated to allow static dewatering of the retained material. When a certain amount of material has accumulated, the screen basket is lifted upwards by an electric chain hoist. The vertical basket movement is supported by a stable carrier and guide rails. These rails are curved in the upper section to ensure a partly automatic discharge into a suitable container. While the screenings are transported upwards in the basket, material which could impair the function of downstream pumps is removed by a fall screen supported on guide rollers.
