Process and apparatus to remove colloids and nitrogen compounds from contaminated water by coagulating the colloids and separating them from the water. The water is then continuously oxidized with chlorine electrolytically to destroy the nitrogen compounds.
Abstract:
A wastewater treatment system and method for remediating wastewater and human waste that is self-contained and that has no connection to a municipal wastewater system and no connection to an electrical grid. The domestic toilet and wastewater treatment system can be powered by a photovoltaic panel as a source of electricity. The system includes an electrochemical cell that allows a waste stream to be disinfected in a few hours to a condition where no viable bacterial colonies can be cultured. The system produces a liquid stream that is suitable for system flushing or for uses in which non-potable water is acceptable. The system can generate hydrogen as a product that can be used to generate power. The system can generate nitrate, urea, ammonia and phosphate for use as fertilizer. The disinfected residual organic solids are also completely disinfected for potential use as an organic soil amendment for agriculture.
Abstract:
A device and process are disclosed for the separate removal of oppositely charged ions from electrolyte solutions and recombining them to form new chemical compositions. The invention provides the ability to create multiple ion flow channels and then form new chemical compositions therefrom. The process is accomplished by selectively combining oppositely charged ions of choice from different electrolyte solutions via the capacitive behavior of high electrical capacitance electrodes confined in insulated containers.

Abstract:
An electrochemical system and method are disclosed for On Site Generation (OSG) of oxidants, such as free available chlorine, mixed oxidants and persulfate. Operation at high current density, using at least a diamond anode, provides for higher current efficiency, extended lifetime operation, and improved cost efficiency. High current density operation, in either a single pass or recycle mode, provides for rapid generation of oxidants, with high current efficiency, which potentially allows for more compact systems. Beneficially, operation in reverse polarity for a short cleaning cycle manages scaling, provides for improved efficiency and electrode lifetime and allows for use of impure feedstocks without requiring water softeners. Systems have application for generation of chlorine or other oxidants, including mixed oxidants providing high disinfection rate per unit of oxidant, e.g. for water treatment to remove microorganisms or for degradation of organics in industrial waste water.
Abstract:
The present invention relates generally to the processing of fluids and/or their carriers. Carriers may comprise pipes, tubes and the like or reservoirs for the distribution and/or storage of fluids. In one form, the present invention relates to a method and apparatus that is suitable for use in the treatment of various fluids, such as water, by introducing at least one chemically active metal into the water and its carriers for disinfection of the water in a controlled manner. The invention also relates to a biasing means for displacement of an electrode arrangement to allow for the introduction of ions into a fluid at a controlled or easily monitored rate that is commensurate with the amount of fluid flow.
Abstract:
In an electrolytic apparatus for removing contaminants from water, a set (110) of spaced apart conductive electrodes (40) in a reaction chamber (54, 112, 114), is arranged in oppositely charged groups of first and second interleaved electrodes with flow paths between them. Non-conductive turbulence inducers (158, 168) on the faces of electrodes (40) are applied to water in the flow paths. One variety is modular elements (158) with stepped increases in width to present a narrow leading edge in the direction of flow. Another variety is a continuous set of wave guides (168) bordering the flow path. Electrodes (40) are selectively powered in patterns creating turbulence, with effective patterns including a first and last electrode powering pattern and a mini-cell electrode powering pattern.
