The Decanter solves these problems by a dual floating weir system which provides a consistent rate of water withdrawal. This allows the removal of water with the least amount of scum or sludge.
When the tank is not being mixed, the material will assume three distinct layers:
Because of the acceleration capabilities of a properly placed weir, large amounts of water can be picked up by the decanter head at very low velocities so the sludge is not drawn into the decanter.
Weir placement is automatic and is accomplished by internal floatation relationships between the weir, the decanter body and the forces of the water.
Give us your tank configuration and desired flow rate and we will design a Decanter System for you.
