Abstract: The present invention provides a new method for the in situ generation of chlorine dioxide from a solution of sodium chlorite and carbon dioxide. The present invention produces effective levels of chlorine dioxide without having to resort to the use of hydrochloric acid, sulfuric acid, hydrogen peroxide, chlorine, sulfur dioxide, or methanol. By eliminating the use of toxic and/or hazardous compounds, the present invention provides a safer means for generating and using chlorine dioxide in a wider variety of applications than previously possible. For instance, the present invention can easily be adapted for the treatment of combustion exhaust gases, flue gases, cooling towers, chilled water systems, contaminated groundwater, and agricultural produce or products.

Abstract: A method of treating and removing volatile organic contaminants from ground water by treating the water with effective amounts of a water-soluble polymeric sequesterant comprising polymers derived from acrylic acid or organic acid, followed by the addition of a biocide, e.g., chlorine, and then subsequently passing the treated water through a packed column or air stripper wherein the volatile organic contaminants are removed by passing air in a counter-direction to the flow of water at temperatures ranging from about 40.degree. to about 200.degree. F.

Abstract: A method of stripping volatile contaminants from ammonia plant process condensate and recovering a stripped process condensate and using same as a high quality makeup water for operating units within the ammonia process which comprises:(a) feeding ammonia plant process condensate to the upper stages of an evaporative stripping tower equipped with a collection basin, and(b) allowing said condensate to flow downwardly against an upward flow of air, and(c) operating the evaporative stripping tower in at least a once-through manner, and(d) collecting the stripped process condensate in the evaporative tower collection basin, and(e) recovering the stripped process condensate from the evaporative tower basin, and(f) reusing this stripped process condensate as water makeup for other process operating units.
