1. A method for co-synthesizing in a flow-through electrochemical cell an activated solution for use in water treatment, comprising:
(a) providing a flow-through electrochemical cell comprising a cylindrical anode and a coaxial cylindrical cathode, a capillary-porous diaphragm coaxial with and between the anode and cathode and defining an anodic chamber and cathodic chamber; (b) introducing an anodic electrolyte solution into the anodic chamber such that the anodic electrolyte solution flows through the anodic chamber and the products of the electrochemical reaction flow out of the anodic chamber, wherein the anodic electrolyte solution comprises one or more electrolyte of the formula MK, wherein
M is selected from the group consisting of alkali metal and alkaline earth metal ions, andK is selected from the group consisting of bicarbonate, carbonate and phosphate ions; (c) introducing a cathodic electrolyte solution into the cathode chamber such that the cathodic electrolyte solution flows through the cathodic chamber and the products of the electrochemical reaction flow out of the cathodic chamber, wherein the cathodic electrolyte solution comprises one or more electrolyte of the formula MX, wherein
M is selected from the group consisting of alkali metals and alkaline earth metal ions, andX is a halogen ion; and (d) subjecting the first electrolyte solution and second electrolyte solution to a current sufficient to create an electrolytic reaction and produce an activated solution comprising a hypohalous acid and one or more ion selected from the group consisting of phosphate ion and bicarbonate ion.
