At such high concentrations, the wetting and drying cycles of the spreading basins cannot meet the ,nitrogenous, oxygen demand (in excess of 100 mg/L), resulting in incomplete nitrification. Ammonium is usually removed by cation exchange onto soil particles during wetting cycles, followed by nitrification of the adsorbed ammonium during drying cycles.
