A two year pilot-scale study was conducted using a biological aerated filter (BAF) to evaluate performance and establish full-scale operating parameters for Tahoe-Truckee Sanitation Agency (T-TSA). It was demonstrated through pilot and full-scale testing, that the system could achieve effluent total inorganic nitrogen (TIN) concentrations of less than 2 mg/L and 3 mg/L for summer and winter periods, respectively. Furthermore, it was demonstrated that both systems could achieve moderate total suspended solids (TSS) and orthophosphate (PO4-P) removals. It was established that the optimum oxygen-to-ammonium (NH4-N) and optimum methanol-tonitrate/ nitrite (NOX-N) ratios were 30 g/g and 2.9 g/g, respectively. The nitrification stage was not sensitive to temperature for either the pilot or full-scale systems. The denitrification stage exhibited temperature sensitivity during full-scale testing. The PO4-P removal was greater during full-scale testing and removal was inversely proportional to temperature.
