-31- ABSTRACT OF THE DISCLOSURE Apparatus for clarifying aqueous liquid uses an electrical field from electrolysis electrodes and a magnetic field at right angles, with one of the fields pulsed. In a swimming pool or spa, chlorine is generated from a small amount of salt in the water, so that addition of chlorine is not needed. In acid aqueous liquid, such as acid mine discharge (AMD) water, the water is clarified, the pH raised, and various elements or ions are precipitated or coagulated. In alkaline liquids, such as oily water, the pH is raised and the oil coagulates out. The apparatus then has many uses, including producing a combination of oxidants, regulating the pH, alkalinity and total hardness, control and eliminate the cathodic scale build-up, and precipitate and coagulate elements, metallic ions and petroleum products as the pH is raised. The foregoing Abstract is merely a resume of general applications, it is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
