Rotary Decanter

QK-BS rotary decanter is widely used to various intermittent circulatory activated sludge process of sewage treatment system (such as SBR and CASS). The rotating decanter can be designed according to the process requirements.

Features

1. Intelligent drowning, the closer to the sludge, the slower the drowning speed and the better the effluent quality;

2. Double-layer limit switch and safety alarm device to ensure greater safety;

3. Strong adaptability: By setting and adjusting the relevant parameters of the inverter through internal parameters, the operating speed and range of the decanter can be adapted to various water quality and quantity;

4. Sealed rotary joint, flexible rotation, good sealing, sealing ring can be replaced without draining;

5. Simple maintenance, Stainless steel underwater parts.

How it works?

The rotary decanter consists of a water-repellent device, a transmission device, a slag pontoon device and a slewing ring. The driving mechanism drives the water-repellent device and the slag-buoy device to rotate around the slewing ring through the telescopic push rod, so that the water sluice mouth moves up and down to achieve the purpose of scooping out the supernatant liquid.

After the rotating decanter receives the draining command, the mooring port is quickly moved from the parking position to below the water surface to stop and drain; after the water is drained, the rotating decanter is connected to the drainage command to quickly move the drowning port from the parking position to the parking position. Stop below the water surface, drain; so repeated

When the rotary decanter reaches the minimum water level, the liquid level switch placed at the lowest water level issues a return command, and the rotating decanter quickly rises back to the initial parking position to complete a working cycle.

A floating barrel is set in front of the decanter basin to make sure the effluent free from surface scums and sludge.
