Claim Text:
1. A method for promoting disinfection and reduction of deposits in a water-containing system utilizing (a) a primary disinfectant and (b) a mixed oxidant solution comprising a plurality of different oxidants produced by flowing at least one starting solution including at least one of salt brine, hypochlorous acid, and sodium hypochlorite through at least one flow-through electrochemical module comprising a first passage and a second passage separated by an ion permeable membrane while electric power is applied between (i) an anode in contact and electrical communication with the first passage and (ii) a cathode in contact and electrical communication with the second passage, wherein a first solution or first portion of the at least one starting solution is flowed through the first passage to form an anolyte solution having an acidic pH, and a second solution or second portion of the at least one starting solution is simultaneously flowed through the second passage to form a catholyte solution having a basic pH, and contacting the anolyte solution with a hydroxide solution to attain a pH value of at least 9.0 to yield said mixed oxidant solution, wherein production of the mixed oxidant solution comprises at least one of the following items (i) and (ii): (i) no portion of the hydroxide solution is flowed through the at least one flow-through electrochemical module, and (ii) the at least one starting solution comprises at least one of hypochlorous acid and sodium hypochlorite, the method comprising: blending the primary disinfectant and the mixed oxidant solution, and supplying an effective amount of primary disinfectant and mixed oxidant solution to the water-containing system; or co-injecting the primary disinfectant and the mixed oxidant solution, and supplying an effective amount of primary disinfectant and mixed oxidant solution to the water-containing system.
