    Abstract: PROBLEM TO BE SOLVED: To provide a filter aid used for filtering an aqueous liquid, having a good filtering action, and suited for precoat filtration. SOLUTION: A method for filtering an aqueous liquid is provided. The method is one comprising filtering the liquid in the presence of a filter aid, wherein the filter aid contains at least one water-insoluble, substantially nonswellable, particulate polymer of an ethylenically unsaturated monomer, and the polymer contains, in the form of a copolymer, at least 20 wt.%, based on the entire monomer weight, 3-6C α,β-monoethylenically unsaturated monocarboxylic acid.
