Abstract |
An investigation into chemical methods for treatment of foul air was conducted by the City of San Diego. A pilot liquid-gas contactor was constructed of PVC lining and stainless steel shafting. Several oxidizing and absorptive chemicals (tap water, sodium hydroxide, calcium hypochlorite, potassium permanganate, copper sulfate, copper chelate, etc.) as well as biologically active materials, were used in the contractor to remove the foul odors in air vented from the sewage sedimentation tanks. Under the experimental sulfide levels of 1.0 to 20.0 ppm H2S (by weight in the gas) good removal was shown by commercial sodium hydroxide, gaseous chlorine and ammoniated copper chelate. Ozone, when used in conjunction with other reactive chemicals, helped in removal of odors other than H2S, as well as H2S. Approximate costs (chemicals only) for treating 1,000,000 cubic feet (28,318.5 cubic meters) of foul air are given. (Author) |
