In an apparatus and method for purifying water, an oxidation forcibly turns colloidal substances into fine particles of oxides, thus increasing the size of the particles. The effluent of oxidation process is treated by ion exchange process, and then treated by membrane process. Because of the increased size of the particles, they are easily removed in the subsequent ion exchange process. The membrane process is thereby prevented from clogging up, and then removes fine particles that cannot be removed by the ion exchange process. Colloidal substances are thus removed effectively from raw water.
