    摘要: A method of precipitating colloidal materials from aqueous systems and a dynamic bimetallic galvanic cell is disclosed, said cell including a metallic electrode which provides a source of flocculating agent and an inert electrode to which the metallic electrode is short circuited. When water containing colloidal particles is passed through the galvanic cell and the electrodes are short circuited, the metallic electrode provides a source of flocculating agent which coprecipitates with the colloidal particles, forming a sediment which can be readily removed. The cell is constructed to maximize the contact between the water and the electrode surfaces and to maintain the metallic electrode short circuited against the inert electrode as the metallic electrode is consumed.

    摘要: Disclosed herein are bleaching systems that contain a peroxide and an activator. The activator is a tungsten containing compound, preferably sodium tungstate or tungstosilicic acid. When such bleaching systems are applied in an aqueous alkaline environment they can bleach mold, fungus, and the like.
