摘要: Apparatus for controlling the coagulant dosage rate includes a charge sensor located adjacent pump measuring net electrical on coagulated water before treatment and turbidity meter effluent after treatment. A programmable controller responds to output signal of continuously adjust maintain set point value in corresponding desired turbidity. To calibration sensor, is also responsive as required so that it corresponds preselected
