摘要： PROCESS FOR CONTINUOUS CATALYZED ELECTROCHEMICAL DECOMPOSITION OF SOLUBLE ORGANICS IN WATER, PARTICULARLY OF UREA IN URINE, IN A DIRECT CURRENT ELECTROLYSIS CELL HAVING AN ANODE AND A CATHODE IN A SINGLE COMPARTMENT. THE WATER OR URINE TO BE PURIFIED IS FLOWED INTO THE CELL, AND THE CONCENTRATION OF CL- ION IS ADJUSTED AS DESIRED WITHIN A CERTAIN RANGE. A CATALYST IN THE FORM OF BR- ION IS ADDED AND VOLTAGE IS APPLIED ACROSS THE ELECTRODES CAUSING OXIDATION OF THE BR- ION TO BR2 AND THE CL- ION TO CL2 WHICH IN TURN OXIDIZE THE ORGANIC MATERIAL IN THE WATER, FOR EXAMPLE UREA IN URINE, TO N2 AND CO2 GASES, AND ARE AT THE SAME TIME REDUCE BACK TO THE BR- AND CL- IONS RESPECTIVELY. THIS CYCLE OPERATES CONTINUOUSLY UNTIL ALL OF THE ORGANIC MATERIAL IS OXIDIZED. THE PROCESS IS USEFUL FOR PURIFICATION OF URINE, SECONDARY EFFLUENT WASTE WATER, PURIFICATION OF SWIMMING POOL WATER AND DRINKING WATER, ETC.

摘要： Method and apparatus for electrolyzing halogen salt solutions having a low halogen salt concentration with direct formation of halogen, using an electrolytic cell comprising at least one anode and at least two electrodes which can function as cathodes. The anode is permanently connected as an anode, a portion of the anodic current is passed through one electrode which can function as a cathode, and a cathodic current is passed through the other electrode which can function as a cathode. The polarity of the electrode functioning as a co-anode and of the electrode functioning as a cathode is periodically changed in cycles of 80-330 minutes.

摘要： A continuous system for disinfecting waste water streams, such as sewage and streams containing organic matter and removing suspended solids therefrom is disclosed. A waste water stream is passed into an electrolytic cell open to the atmosphere and between a series of electrically charged parallel electrode plates. A controlled amount of electrolyte such as sodium chloride is added to the waste water stream before it passes through the electrolytic cell. During passage between the electrode plates a foam is generated which entrains suspended selected nutrient solids contained in the waste water stream, the foam removed by skimming and/or suction means. The treated water discharged from the electrolytic cell is filtered to remove additional non-nutrient suspended solids not entrained with the foam. A portion of the treated water from the electrolytic cell is recycled and reinjected into the influent stream. Control means are included to control residual chlorine in the effluent discharged from the electrolytic cell while maintaining high dissolved oxygen in the effluent.

摘要： A compact chlorine generation device generates chlorine and usually ozone. The device is water cooled. A power transformer has a housing thereabout in heat conductive contact therewith. A highly heat conductive metal frame is attached in direct efficient heat conductive relation with the housing. The frame has a conduit therethrough generally adjacent to the housing. A metal block has a semi-conductor power rectifier held in a cavity therein and in thermal contact therewith. The block is attached in direct heat conductive relation with the frame. A coolant is flowed through the conduit thereby cooling the transformer and the rectifier. A chlorine generating electric cell has an anode and a cathode which are connected to the respective DC output poles of the rectifier. The coolant which exits the conduit is led to the cell wherein it serves as the electrolyte. Outflow liquid from the cell and having an enhanced chlorine level dissolved therein is directed to a reservoir which may be a swimming pool, a health spa, a purified water supply, or the like. The chlorine content of the reservoir is thereby increased to provide a sterilizing and disinfecting action.

摘要： A self-contained apparatus for concentrating and dialyzing protein and other macromolecular liquid samples rapidly to precise, predetermined microliter quantities. An elongate rod of predetermined volume, having irregular cross section along its length, is disposed within a semi-permeable membrane sample container in spaced juxtaposition with the membrane to maximize the rates of concentration and dialysis. The rod also cooperates with a sample collection chamber sealingly interconnected detachably with the bottom of the membrane to automatically provide a predetermined final sample volume precise to within two microliters. The rod includes a member, detachably coupled with and extending into the cllection chamber for providing the collection chamber with a predetermined volume.

摘要： The water treatment apparatus is provided with one or more turbidity meters in the inlet line to the electrocoagulator and the outlet line from the flotation stage. The voltage across the coagulator electrodes is controlled in response to a controller which receives signals from the respective turbidity meters. When the turbidity increases in either the inlet line or outlet line, the voltage is increased and when the turbidity decreases, the voltage decreases. In addition, upon an increase in voltage above a top limit, compressed air is charged into the coagulator while the rate of flow of recycled sludge is increased. Also, the pressure in the coagulator is maintained during operation of the air compressor.
