Abstract

PURPOSE: To provide a filtration process wherein a filter medium and suspended substances are easily separated and back washing water containing the suspended substances at high concentrations is extracted by carrying out extraction of the filter medium and washing intermittently and thus eliminating a decrease in concentration of the back washing water.
