Abstract
A solid-liquid separator and a process for washing the same wherein SS (sended solids) caught in space portions of a filter medium in a tank are caused to flow out from the space portions and be suspended while at least part of the filter medium is maintained in a fluidized state by air washing, and rapid drainage through a lower portion of the tank causes the SS in the suspended state to be rapidly removed without being again caught into the space portions of the filter medium.
