Abstract:

A pilot learning was performed at the Fox River Fiber improved paper dispensation company in DePere, Wisconsin, to establish the amount to which inoculation of oxygen and ozone could decrease the high chemical oxygen command, COD, in the sewage and the efficiency of the ozone/oxygen stream in suppressing construction of hydrogen sulfide gas in downstream sewage appearance. Adaptive Ozone Solutions, LLC, complete the oxygen/ozone making and injection scheme. Samples were analyzed both before and after oxygen/ozone insertion. Hydrogen sulfide gas was incessantly monitored at sewer stations downstream of Fox River filament. Consequences showed that with an extremely short contact time, effluent COD was concentrated by over 20%. A straightforward kinetic model predicts that a contact time of fewer than 40 minutes possibly will decrease COD by as much as 65%. In calculation, downstream hydrogen sulfide gas manufacture in the sewage mains was also improved proscribed, such that expensive Bioxide applications could be concentrated. Hydrogen sulfide gas, fashioned as an effect of these conditions, is the most common odorous gas found in municipal wastewater compilation and management systems.
