Impact of Odor and Corrosion Control Practices on the Influent Readily Biodegradable COD fraction and Biological Nutrient Removal System Performance
Abstract:The key to successful Biological Nutrient Removal (BNR) is influent wastewater quality. BNR needs volatile fatty acids (VFA) or sufficient rapidly biodegradable COD in the influent to trigger the phosphorus release mechanism. Denitrification also requires carbon, and the system denitrification rates are higher if the influent carbon is soluble. Corrosion control and odor control techniques used in the collection system, which hinder VFA production or destroy VFA, can have an adverse impact on the BNR process. Specifically, the use of nitrate and oxygen to stop anaerobic fermentation not only stops fermentation, but biological consumption of nitrate and oxygen converts soluble biodegradable COD into biomass. This conversion results in a shift in the influent characteristics to a WWTP and will affect BNR processes.
