Environmental Diverter Gates
KWS Diverter Gates are custom designed to provide a compact and effective means to separate low-solids biosolids during operation of a centrifuge. Typically, low-solids biosolids are characterized by the centrifuge manufacturer as those that result in a main drive torque of less than a defined value. This torque threshold output is used to open and close the diverter gate and allow low-solids biosolids to bypass the downstream process and return to the centrate tank, or as required by the process design.
KWS Diverter Gates can be provided with electric or pneumatic actuators to accommodate required opening and closing times, depending upon process requirements.

Advantages of Using Environmental Diverter Gates
- Low Solids Biosolids are Diverted Back to Process – When low solids are detected, gate closes and diverts liquid to drain line. As soon as high solids are detected, diverter gate opens to deliver biosolids to downstream process.
- Compact Design Fits Any Centrifuge – Custom-designed to fit in almost any space and with any drain line configuration. Gate can be actuated electrically, hydraulically or pneumatically.
- Low Energy Consumption – Alternative methods of low solids separation require the use of additional conveying and process equipment.
- Versatile, Rugged and Maintenance-Free – Stainless steel slide plate rollers with bronze bushings are self-lubricating. Inlet and discharge transitions can be adapted to fit any opening configuration.
