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 the type of floating decanter, use float to move up & down in the basin and employ 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. Using a stopper restricts the top and bottom movement of the decanter. It can be operated manually or PLC-based.
