Abstract
Waste water containing suspended particles such as mineral oil, fats, proteins, fibers, and biodegradable materials, etc., is clarified by passing said water over a plurality of electrode banks whereby gradient current density zones and gradient energy zones are used to create microbubbles which float the particles to the surface where they may be skimmed off.
