20110180422Electrocoagulation treatment process - A method of improving electrocoagulation (“EC”) treatment processes for treating waste water and similar applications. The method includes providing a variable power supply that outputs an alternating current (“AC”) to one or more EC treatment cells. The alternating current from the variable power supply is rectified before delivery to the EC cell. As an intermediate step between the variable power supply and rectification, the method described and claimed here uses a variable step down transformer to modify the output delivered to the EC cell.07-28-2011
20100270171A System And A Method For Reducing The Amount of Liquid In A Biological Mass - The present invention is directed toward a method and a system for reducing the amount of fluid in a biological mass comprising solids and fluid in the form of liquid and gas. The system includes a temporary storage container for receiving and temporary storing a biological mass, at least one separator arranged to receive the biological mass from the temporary storage container and separate at least a portion of the fluid of the mass from the solids of the mass, a solids container for receiving the solids fraction separated from the biological mass, and a liquid-purifying device arranged to purify the liquid which is separated from the mass by means of the separator. The system is substantially fluidtight towards the surroundings and the separator includes a screen cloth and a device for inducing a fluid flow. The fluid flow is arranged to carry a portion of the liquid out of the mass and through the screen cloth, the essential part of the fluid flow has been recirculated in the system (10-28-2010
20100270170SYSTEM AND PROCESS FOR CONVERTING NON-FRESH WATER TO FRESH WATER - A method of converting seawater, waste water, brackish water and polluted water to fresh water, referred to as “The Rosenbaum-Weisz Process”, is disclosed. This method utilizes high temperature electrolysis to decompose the seawater into hydrogen, oxygen and salts/minerals. The generated hydrogen and oxygen are then combusted in a high temperature combustor to generate superheated steam. The heat from the superheated steam is then removed by a high temperature heat exchanger system and recycled to the high temperature electrolysis unit. The superheated steam is then condensed, as a result of the heat extraction by the heat exchanger system, to produce fresh water. The recovered salts/minerals can be sold to generate additional revenue.10-28-2010
20120247972PROCESS FOR REDUCING THE CONCENTRATION OF HYDRATE INHIBITORS IN WATER USED FOR OIL AND GAS PRODUCTION - Reducing the concentration of kinetic hydrate inhibitors in produced water may be accomplished by treating the produced water using a method selected from the group consisting of chemical adsorption, solvent extraction, chemical coagulation, electrochemical coagulation and combinations thereof. Such reductions may in some instances allow for the reuse of produced water for irrigation or recycle in oil and gas production.10-04-2012
20120255872Electrokinetic Process And Apparatus For Consolidation Of Oil Sands Tailings - A method is provided of treating liquid tailings using electro-kinetics by creating a variable voltage between two electrodes in the tailings. Flocculation and water release from the tailings is induced by establishing an electrical field between the two electrodes. The electrodes are connected to an electrical power source having the variable voltage to create a cathode and an anode. Compacting the flocculation solids and removing further water released from the compacting solids allows for the creation of a compacted material having a desired load bearing capacity.10-11-2012

Parallel pairs of electrode plates are situated in vertical position in the container or tank and form parallel vertical passages therebetween for the water to be treated. In the pairs of electrode plate at least one electrode plate comprises holes connected to a feed pump for an auxiliary medium. Said pairs of electrode plates are positioned between the inlet and outlet in the container or tank such that in at least part of the flow route between the inlet and outlet the water passes upwards in the vertical passages. The feed pump for the water to be treated and/or the feed pump for the auxiliary medium is a pulsating feed pump.11-29-2012
20080223730ELECTROCHEMICAL TREATMENT OF SOLUTIONS CONTAINING HEXAVALENT CHROMIUM - There is disclosed a process of electrochemical reduction, optionally coupled to a final stage of chemical finishing, of solutions containing hexavalent chromium.
