Abstract

PURPOSE:To carry out the backward-washing of filter element regardless of the pressure of treated water and to eliminate the need of preparation of water source for back-washing by using a part of filtrated water accumulated in an accumulating vessel as the back-washing water. CONSTITUTION:When the need of back-washing is detected by a control means 37, such as that the pressure difference between an inlet pipe 7 and an outlet pipe 9 exceeds a certain value, a part of filtrated water flowing through a treated water pipe 35 is introduced to the accumulating vessel 39 from a 1st pipe 36. When it is detected that the filtrated water for back-washing is accumulated enough in the accumulating vessel 39, the back-washing water is suddenly discharged from the accumulating vessel 39 to flow into the element chamber, and back-washing for one of the filter elements is carried out. Thus the accumulation of back-washing water in the accumulating vessel 39 and the discharge of the back-washing water are repeated until the pural filter elements are all back-washed, and then the ordinary filtration is started again.
