SYNOPSIS E utrophication and severe oxygen depletion of the Danish seas have created a demand for nutrient removal from wastewater. Effluent concentrations from 2 to 0.3 mg/l P can be achieved by chemical precipitation. Nitrogen is best removed by combined nitrificationdenitrification. Effluent concentrations down to 3 to 4 mgll ‐ can be achieved. There is technical and economical potential in combined biological P‐ and N‐removal at marginal extra cost. Contact filtration has to be included to reach low concentrations of P.
