  • Process for the production of highly pure concentrated slurries of sodium hypochlorite
    Patent number: 5194238
    Abstract: A process for producing sodium hypochlorite slurries admixes a hypochlorous acid solution having a concentration of 35 percent or greater by weight of HOCl with sodium hydroxide at a temperature below about 25.degree. C. The reaction produces a slurry of sodium hypochlorite pentahydrate in an aqueous solution of sodium hypochlorite where the sodium hypochlorite is present in a concentration of at least 35 percent by weight of NaOCl. The sodium hypochlorite slurries have improved stability and greatly reduced amounts of sodium chloride. The process for produces high strength sodium hypochlorite compositions of high purity having improved yields and reduced product decomposition.

  • Process for purifying wastewater with hypochlorous acid
    Patent number: 5120452
    Abstract: A process for treating wastewater the improvement which comprises admixing with the wastewater at least 0.5 percent by weight of a solution consisting of hypochlorous acid having a pH of less than 3 to prepare disinfected wastewater having substantially no available chlorine residual.The novel process of the present invention provides rapid, intimate mixing of the highly pure, highly acidic hypochlorous acid solution with the wastewater stream to disinfect wastewater bodies while minimizing unwanted side effects. The process eliminates the need for storing and handling pressurized gaseous or liquid chlorine.
