Table 7.3: Recommended performance monitoring requirements for physico-chemical treatment processes Test/Check Frequency Remarks Chemical Precipitation Flowrate Daily pH Chemical dosage system To calculate the chemical dosage To ensure it’s working properly Metals (if process is for metals removal) Influent & effluent Oxidation/ Reduction ORP Metals COD, if relevant

Table 7.3 Continued Process Test/Check Frequency Remarks Carbon Adsorption (a) Flowrate Daily Contaminant to be removed (e.g. COD) Daily;more frequent as breakthrough is approached Influent & effluent Pressure difference
