Abstract: A waste water clarification system is mounted on two road-transportable trailers which meet height and weight regulations and require no additional permitting. An elongate, low-profile clarifier having inclined plate packs supported therein utilizes the dropped bed portion of the first trailer to maximize the usable height to meet transport requirements while optimizing clarification of the waste water therein. Sludge produced in the clarifier section is thickened by gravity in a thickening section mounted on the first trailer. The thickened sludge is delivered to dewatering apparatus on the second trailer which also houses a lift tank for clarified water, chemical storage tanks and a control room for system control apparatus. Linear conveyors, in steep-walled troughs in the bottoms of the clarifier and thickening sections, slowly move the sludge to outlets therein, the speed being slow enough that a sludge blanket which develops in or above the troughs is not disrupted.

Abstract: A method for separating contaminants from a aqueous source containing contaminants. In one embodiment, the method involves the use of a high powdered oxidant dissolved within the aqueous system. The gas is dissolved within a reservoir in the aqueous solution and the pressure within the reservoir is controllable. This allows maximum contact of the oxidizing dissolved gas with the contaminant material. Once oxidized, the outlet of the reservoir is adapted to permit hydraulic cavitation. The net effect of the cavitation is to induce a foam formation which foam transports a floc into a separate phase from the aqueous solution. In this manner, the process is effectively a dissolved oxidizing gas mass transfer process. In another embodiment, the process may be augmented by electrocoagulation. This involves the use of an electric cell which is disposed within the reservoir containing the oxidant material.
