Abstract

A method for estimating incoming pollution loads during operation of a municipal wastewater treatment plant involves the step of continuously measuring the conductivity and turbidity of the raw water to be treated. The concentration of a pollutant in the raw water to be treated is estimated as a function of the measured conductivity and turbidity. The flow rate of the raw water to be treated is also continuously measured. The load of the pollutant in the raw water to be treated is estimated as a function of the estimated concentration of the pollutant and the measured flow rate. The estimated pollutant load allows adjustment of downstream treatment for eliminating the estimated total load of the pollutant.
