PROBLEM TO BE SOLVED: To provide a method for filtering suspension colloid at a high removal rate. SOLUTION: This filtering method comprises a step to obtain a supernatant liquid by settling the suspension colloid-containing liquid to be treated, a step to filter dynamically the supernatant liquid obtained at the preceding step by a filter medium having substantially uniform pores and a step to store the permeated liquid obtained at the preceding step in a water storage tank.
