Hydraulic Clarifier Drives

Hydraulic Powered Bridge Supported Drive Units (Type-H)
Technically advanced hydraulic powered Type H drives are available in a wide range of operating torques and output speeds. Power is introduced through a standard “C-Face” mounted motor connected to a low speed, high torque hydraulic power system with integral valves, pump, hydraulic motor, filter and appurtenances fully enclosed in a 304 Stainless Steel housing / oil reservoir.

All Kusters Water clarifier and thickener drives are designed in accordance with the latest AGMA and / or ISO standards to ensure the absolute highest quality. Assembly and inspection of every unit is performed at Kusters facility prior to shipment.

Overload Protection
Precise torque monitoring is a major advantage of the Type H drive system. The overload system includes alarm and motor cut-off switches that are activated by an increase in operating pressure in the hydraulic system that is directly proportionate to the torque load on the rotating mechanism. Each unit includes a maximum torque pressure relief valve which takes the place of the less accurate mechanical shear pins and allows the unit to gradually stall without damage to the rotating mechanism. Torque is monitored with a liquid filled gauge that reads in actual operating torque (Ft-lbs) or (N-m).

LA-EDI Clarifier Inlets 

The Los Angeles Energy Dissipating Inlet, (aka. LA-EDI) was developed to address short circuiting issues common within the clarifier center well. The patented inlet design promotes flow impingement, enhances flocculation and minimizes short circuiting; the net result is the ability to handle higher flow rates through the clarifier basin. For more than 15 years, Kusters Water has been providing customers around the world with superior clarifier designs utilizing LA-EDI inlets.  LA-EDI designs are offered in two configurations.  Type I –Separate LA-EDI well, located within a feedwell. Typically installed on larger clarifiers >60ft.  Type II– Integral LA-EDI, which incorporates the feedwell baffles into one well. Typically installed on smaller clarifiers < 60ft.

Solids Contact Clarifiers

Kusters Water’s units employ proven recycle solids contact principal for highly efficient flocculation, sedimentation, and clarification in a single compact basin. Solids contact units are widely used for the removal of turbidity for lime softening, and for chemical coagulation in municipal and industrial applications.

The slow speed, large diameter impeller recirculates large quantities of fresh precipitate through the recirculation drum, achieving superior solids and complete chemical reaction. The formulation of settleable floc particles occurs in the large, slow mixing reaction cone. An automatic sludge discharge system maintains an optimal solids volume along the clarifier bottom for efficient solids contact within the mixing zone.

The throughput follows a spiraling downward path to the outlet under the edge of the skirt. That is followed by circumferential, vertical rise clarification – Free of density currents and short circuiting, making possible an unusually clear overflow and dense underflow in an easily controlled, hydraulically and chemically stable system. As the flow passes upward, the decreasing upflow velocities of the floc particles cause dynamic separation of the solids from the treated water.

Radial launders provide uniform effluent discharge while maintaining the upflow pattern. The radial launders are available with v-notches or submerged orifices.

Standard Scraper Clarifiers 

Pier supported scraper clarifiers are designed for all applications involving sludge removal. Flow enters through the center pier then discharges through outlet ports located at the top of the center column into either a controlled energy inlet or feedwell. The energy inlet / feedwell dissipates the influent energy, minimizes density currents and enhances settling. Solids are collected at the bottom of the basin and raked to a collection sump located in the tank floor. The clarified effluent exits over the weir plates and out of the basin.

Clarifiers are offered in sizes ranging from 10′ to 250′ ft diameter. Primary, Secondary and Final clarification are typical applications. Every unit includes a worm or spur gear drive unit designed in accordance with the current AGMA standards to ensure the absolute highest quality and a minimum 20 year service life.

Suction Lift Clarifiers

Kusters Water rapid sludge removal clarifiers are specifically designed to provide quick and uniform removal of return activated sludge (RAS), Model HBSL collectors utilize collection pipes located at multiple points along each arm. Suction generated by a differential head developed from the partially submerged return sludge well located at the center of the clarifier. Each collection pipe is equipped with a return flow variator that controls the rate of sludge return and provides a visual indicator of the quality of RAS. Every pipe discharges into the rotating center return sludge well, then by gravity exits through a vertical steel pipe located inside the center pier. The size and quality of pipes are selected according to the RAS flow rates.

Vertical Tube, Suction Lift Clarifiers (HBSL-S)
Model HBSL-S, featuring vertical draft tubes and rotating sludge collection troughs simplify operations. The unique design of the vertical RAS pipes are less prone to clogging, easy to clean, provide better visibility of RAS flow, and improve surface scum collection via the rotating RAS trough, resulting in no scum pits required, no scum pumps, etc.

Tapered Header Suction Clarifiers 

Kusters Water rapid sludge removal clarifiers are specifically designed to provide quick and uniform removal of return activated sludge (RAS), each clarifier utilizes a rotating tapered sludge collection header and manifold assembly to remove activated sludge. Settled solids are collected through orifices located along the full length of the header. Varying orifice size and spacing are computer generated to provide the desired velocities throughout the entire assembly. Suction is typically provided by direct connection of the return activated sludge pumps to a central draw-off manifold at the tank bottom. An optional rake arm opposite the sludge header is available to collect any remaining solids. Sludge headers are offered in either single or dual configurations.
