Raw water sample charge is determined using the CCA3100 Laboratory Charge Analyzer. Titration is performed using a micro-pipette and a coagulant (in this case, a cationic coagulant). Mixing is done with a magnetic stirrer. As the coagulant is added, the net charge becomes more positive. The endpoint is “0” and the amount of titrant (coagulant) that is necessary to reach “0” is determined (in ppm). That becomes the target dosage for the process (clarifier, settler, filter, DAF, etc.). Essentially, a jar test evaluation of current raw water conditions completed in less than 5 minutes.
