Coagulant Charge Analyzer
The CCA is a laboratory unit that rapidly determines the appropriate coagulant dosage using a simple titration and streaming current technology.
Should the source water quality suddenly change or if the plant uses different water sources, the operator can make timely chemical adjustment based on the information obtained by dosing a jar to the desired streaming current value.
Using a simple titration, the CCA3100 Coagulant Charge Analyzer enables operators to determine the optimum coagulant dosage much faster than conventional jar testing (five minutes or less). The CCA3100 can also be used to determine the “charge demand” of a sample, helping to identify charge-related process excursions in applications like papermaking. The measurement cell consists of a reciprocating piston in a probe assembly. The movement of liquid between two stainless steel electrodes creates a voltage signal indicating net charge of the sample. This signal is displayed in a range of -10.00 to + 10.00. The CCA is simple to use and provides repeatable results.

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.
