Streaming Current Detectors :
Milton Roy’s Streaming Current Detector (SCD) is used to monitor and control coagulants in water or wastewater treatment. SCD is an analyzer which measures the net electric charge of particles after coagulant dosing. This measurement is then used to establish a set point to control coagulant dosing as influent turbidity changes and assures a consistent effluent quality.
