Abstract: Apparatus and process for removing colloidal, oxygen demanding and odor causing organic materials, inorganic materials and other pollutants from waste water is provided. The initial pH and resistivity of the water is measured and adjusted to predetermined values. The color of the water is then measured and organic and inorganic materials are caused to precipitate from the water which is then subjected to a predetermined density of electrical current. The electrolysis coalesces colloidal materials which are removed mechanically and causes additional material precipitation, as well as acting to kill bacteria, viruses and other organic matter. Additional inorganic matter precipitation is induced and the water has a final pH, color and resistivity adjustment. An oxidizing agent is added to further reduce oxygen demanding and odor causing organic material and act on bacteria and other organic matter remaining. The water is then reusable or may be discharged into streams or sewer facilities.
