Effluent Decanter

Floating decanter is used in sequencing batch reactors (SBR) to discharge settled water from the tank. The basic design principle of the decanter is to utilize spring-loaded non-return valves to isolate effluent piping from the surrounding mixed liquid when the tank is in-filling. The scum/solids excluding type floating decanter do not have electro-mechanical components and it eliminates motors, gears, and drive units. A simple open/close valve is used to control flow through the decanter. No in-basin components require routine maintenance or scheduled replacement. The system can be operated either manually or can be PLC based.

Effluent Decanter Overview

The scum/solids excluding type floating decanter use float to move up & down in the basin, and employs spring-loaded non-return valves to isolate the effluent piping from the surrounding mixed liquid. The design eliminates motors, gears, drive units, and other electromechanical components. The top and bottom movement of the decanter is restricted by the use of a stopper. It can be operated manually or PLC-based.
