  • Publication number: 20230373833
    Abstract: 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.

  • Patent number: 4822474
    Abstract: A residual analyzer assembly including an analyzer probe, typically of the amperometric type having a stable zero calibration, and a working fluid sampler system having means for backflushing the flow so as to periodically cleanse the system. The residual analyzer probe having two bare electrodes operating as a working electrode and a counter electrode. The working electrode being formed in a double spiral helix with the counter electrode being formed in an outer peripheral ring closely adjacent the working electrode. The probe also including a third electrode within an electrolytic solution and positioned behind a membrane located directly behind the working electrode. The three electrode system operated utilizing a potentiostat type circuit. The working fluid sampler system adapted to sample a portion of the working fluid flow and maintain a constant pressure into a flow block. A controlled amount of reagent being added for proper residual analyzation of the sample.
