WASTEWATER GRIT CLASSIFIER FL/CDS SERIES
The wastewater grit classifier receives the liquid with grit into the inlet hopper where the grit settles to the bottom by means of gravity. The inclined screw captures the settled grit and transports it to the discharge chute where it is received by a suitable bin or conveyor.
Features:
- Separation of grit from liquid flows
- Receives settle-able grit in liquids from upstream process
- Grit settles in inlet hopper by gravity
- Organic material is removed by turbulence in the inlet hopper
- Additional washing by optional air or water jet agitation
- Optional fats, oils and grease removal in inlet hopper
- Inclined shaft-less or shafted screw transports settled grit to discharge end
- Grit dewaters by gravity in the transport zone
- Dry grit is discharged vertically into receiver bin or conveyor
- Trough wear protected by metal or HDPE liner
