An electrochlorination process includes treating water from a source of water in an advanced water conditioning system that removes at least a portion of anions and cations from the water and produces demineralized water, blending the demineralized water with sodium chloride to form a brine solution, and treating the brine solution in an electrolyzer to form a disinfection solution including sodium hypochlorite having a concentration of chlorate of less than 0.25 mg/L.

Process of using demineralized water for chlorate reduction in on-site brine electrochlorination systems

A system containing a reactor vessel including zero valent iron media, a source of a conditioning additive, a source of a reaction additive, and a process control subsystem is disclosed. A method for reducing a concentration of one or more contaminants in contaminated water including contacting zero valent iron media with a conditioning additive, contacting contaminated water with conditioned zero valent iron media, and introducing a reaction additive is also disclosed. The conditioning additive and reaction additive may each contain an aluminum salt.
