Description
OPERATING MODE
The grit removal system operates by decantation to remove grit, sand, and rocks. Influent water flows slowly into the inlet hopper to allow grit to settle at the bottom of the tank. Then, captured grit is conveyed upward by the shaftless spiral. Effluent water evacuates through the top of the hopper to allow complete grit removal. A spray bar and cyclone system is optional.
Grittec can be installed in combination with our Hydrocyclone.
Features & Benefits
Efficient grit classification is achieved through the utilization of a tank that is both deep and wide.
