Abstract/Contents

Abstract: Results of fed-batch operation of the Photosynthetically Oxygenated Waste-to- Energy Recovery (POWER) system have demonstrated its ability to treat urban wastewater while inactivating native pathogenic bacteria in the primary effluent. To hinder bacteria regrowth and to inhibit viral activity, a residual chlorine level is required prior to discharge of the POWER system effluent.
Carcinogenic disinfection byproducts (DBP) may result from disinfection with chlorine. EPA’s discharge standards for two types of DBPs include: trihalomethanes (THM) and halacetic acids (HAA). Nitrosamines (NA) are unregulated but are of growing concern in treated wastewater.
To comply with discharge standards for treated effluent, this research aims to compare DBP formation potential in the POWER system against that in secondary system with chlorination.
