Filtering method of a colloidal solution
A filtering method is directed to a wastewater of CMP process, which includes sub-micrometer particles suspended as colloid. The wastewater is filtered by a gel membrane formed on a surface of plastic filter. A coagulant or a pH adjuster is added to the wastewater so that the sub-micrometer particle...
