Do operating costs conform to environmental impact after introduction of charges on discharge of wastewater? A study on optimization of phosphorus removal at two Danish wastewater removal plants shows that this is actually the case. By measurement of inlet and outlet concentrations and of chemicals added it was possible to determine the relationships between chemical dosing and phosphorus discharge and thus calculate the operational cost and environmental impact of different dosing/discharge levels.
