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.

Claim (Index 26):
A method for On-Site Generation (OSG) of an oxidant solution for chemical water treatment and disinfection comprising in an electrochemical cell, the electrochemical cell comprising an anode comprising a conductive ultrananocrystalline diamond on a substrate and a cathode provided interior to the electrochemical cell, wherein the anode and cathode define an active area of the cell, said method comprising:\n supplying to the electrochemical cell an aqueous feedstock electrolyte to enter and exit a single fluid path formed between the anode and cathode, the aqueous feedstock electrolyte consisting essentially of a salt solution having a concentration ranging between 0.1 Molar and 3 Molar, said salt solution being selected for electrochemical generation of an oxidant comprising one or more of hypochlorite, other free and available chlorine (FAC), hydrogen peroxide, chlorine dioxide, ozone, mixed oxidant and peroxydisulfate; in an operational cycle, electrolyzing the aqueous feedstock electrolyte at a current density in the range from about 150 mA/cm 2  to about 1000 mA/cm 2  to produce an oxidant solution comprising said oxidant; and supplying said oxidant solution from the electrochemical cell.
