Nitrification in rapid sand filter: phosphate limitation at low temperatures – unprocessed
In winter 1995-1996 the RSF of AWS River-Lake Waterworks suffered from ammonium breakthrough. Research indicated that the nitrification was limited by stagnated growth of the nitrifying bacteria due to low phosphate concentrations at low temperatures (0-3°C). Phosphoric acid was dosed prior to the RSF (dose 35-50 μg PO43- -P.l-1) to stimulate bacteria growth. Two weeks after…
