Description:
This study investigates the treatability and fate of 28 organic RCRA compounds in a combined organic removal and nitrification process and by secondary effluent gravity filtration. .8 L/min pilot-scale extended aeration wastewater treatment system with dual media effluent filter was utilized for the study. t a total concentration of approximately 1.5 mg/L organics (sum of the concentration of all 28 RCRA compounds) into the aeration basin, most of the compounds were removed to below detectable limits by secondary treatment under either acclimated or unacclimated conditions. he effectiveness of the effluent filter in removing organic compounds could not be assessed as most of the compounds entering the filter were already reduced to below detectable levels. mmonia removal was significantly impaired at a total concentration of 19.2 mg/L organics into the aeration basin. OD reduction was apparently not inhibited at any of the spike concentrations tested.
