Design and Operation of Floating Decanter

The principle and key points in the design of floating decanter with automatic rubber ball valve were introduced, and the performance of domestically produced large floating decanter was described. The study result shows that the decanter is characterized by simple and reliable configuration, steady operation, deep decantation and wide adaptability. Its weir loading is decreased gradually with the decanting of water. The floating decanter can be used in SBR process, with good effluent quality and large decantation capacity.
