Hydro International offers the resources you need to achieve effective grit removal and handling.

Backwash and Underflow System

The separated grit, which accumulates in the collection area, is discharged from the vessel through the underflow pipe located at the bottom of the Grit King®. A period of fluidizing prior to discharging the collected grit through the underflow pipe is recommended. Hydro International’s fluidizing system prevents the collected grit from compacting in the collection area and releases entrapped organics, which rise back into the vessel to continue on for further treatment. The fluidizing process also aids in transporting the accumulated grit to the grit dewatering equipment.

Hydro International’s backwash system is fed with plant or potable water and is supplied complete with a solenoid valve and a manually operated ball valve. Where appropriate, air backwash can be used in lieu of water.

Control Panel

The Grit King system is controlled by a state-of-the-art PLC based, NEMA 4X, 7 or 12 control panel. The panel is equipped to activate and terminate the operation of the backwash system, grit underflow system, and grit classifier. Its flexible design allows for automated or manual operation.
