PROBLEM TO BE SOLVED: To provide a method for causing the high and stable average transmission flow of an aqueous suspension containing inorganic and organic particles. SOLUTION: In this method, the pH value of the suspension and the zeta potential of the particles are checked, a porous ceramic filter having membrane layers comprising at least one metallic oxide of the same polarity as the particles in the suspension at the pH value of the suspension is arranged, the suspension is made to flow through the porous filter, and a filtrate is drawn out. |
