Simple and reliable single-float decanters with the overflow edge immersed at a constant depth. Drain capacity depends on the pump parameters or the degree of opening of the gate valve at the hose outlet at the gravity drain. The decanter can operate with any fluctuations in the sewage level.
Two or four-float decanter with adjustable drain trough immersion depth. The edge of the overflow is submerged to a pre-set depth below the sewage surface.
The decanter drain trough is stationary relative to the floats, and the overflow edge is immersed at a preset depth below the sewage surface. The discharge of overlying water is regulated by changing the immersion depth of the floats thanks to compressed air lines supplied to the floats.
The sewage drain is regulated by changing the height of the drain trough relative to the floats using an electromechanical actuator, which enables remote control of the trough's immersion depth. Inductive limit sensors allow operation in automatic mode.
