decanterIt is a necessary mechanical device for treating wastewater using the sequencing batch reactor (SBR) method. The batch activated sludge process (SBR) for wastewater treatment has developed rapidly due to its advantages of simple process and low investment. Its basic operating procedures consist of five basic processes: filling, reaction, settling, drawing, and idle. The period from the inflow of sewage to the end of standby time is one cycle. The decanter can achieve timed and quantitative discharge of standard treated water, thereby enabling the SBR tank to achieve the ultimate goal of continuous sewage treatment.

The rotary decanter is mainly used to start decanting water during the drainage period, and is usually stopped at the upper part of the highest water level in the pool. The decanting tank slowly descends under the drive of the driving device (synchronized with the descending water speed) to start decanting water, and the water continuously flows out through the decanting tank, branch pipes, and main pipes. When the decanter reaches the predetermined depth, the driving device begins to reverse, and the decanter quickly returns to its highest position, waiting for the next command.
