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.
- 5 Minute Jar Test on Display at ACE15 in Anaheim Posted on: 06/08/2015
For over 25 years Chemtrac has exhibited at the AWWA Annual Conference & Exhibition. This week, at ACE15 in Anaheim, they are introducing the next generation Laboratory Charge Analyzer (LCA), along with the new and improved Benchtop/Portable Particle Counter (PC5000). Of course, on display will also be Chemtrac’s latest models of online Streaming Current Monitors, Particle Counters, Chlorine Analyzers, Organics Monitors, as well as the HydroACT series of water analyzer products.
- Tennessee Closes the Gap in Operator Training Posted on: 01/09/2015
Continuing education for Water Treatment Operators, and keeping up with the latest available technologies is quite essential. Personnel from five Tennessee water plants took advantage of Chemtrac’s “Optimizing Coagulation Using Streaming Current Measurement” workshops during 2014. Operators from La Vergne, Madison, Centerville, Harpeth Valley, and Bon Aqua learned how the Laboratory Charge Analyzer saves valuable time, and gives added coagulant dose determination precision as compared to routine jar tests.
- New Instrumentation Causes Operators to Rethink Water Treatment Procedures Posted on: 01/06/2015
In 2014, the city of Franklin, NC, purchased a Chemtrac on-line Streaming Current Monitor at the advice of their state regulatory agency. This was to help them manage USEPA Maximum Contaminant Levels (MCL) for disinfection by-products. Historically, plant operators determined their coagulant dosage based on the turbidity level in their river source. Both alum and lime were used to treat a cold, low alkalinity, and often turbid river influenced by heavy rain events.
- Chemtrac Exhibits at 75th Annual International Water Conference Posted on: 12/01/2014
It was a milestone year for the International Water Conference. The 75th Anniversary IWC was held November 16-19, and Chemtrac was in San Antonio to take part. Of particular interest to the Chemtrac booth visitors was the PC4400 Particle Counter with the ppb volumetric concentration readout. This is particularly useful in monitoring corrosion product transport in the power industry. The PC4400 is also quite popular for optimizing filtration in RO pretreatment applications, and correlating to (and monitoring) Silt Density Index (SDI) trends.
- WQTC Exhibitor for Over 20 Years Posted on: 11/25/2014
Chemtrac was proud to exhibit at the 2014 Water Quality Technology Conference in New Orleans. A longtime supporter of WQTC, Chemtrac is one of just seven companies that have exhibited at this industry-leading technical conference for over 20 years. At the booth they showcased the soon-to-be-released, new-and-improved bench-top charge analyzer (which will replace the CCA3100). The laboratory charge analyzers are used to quickly determine the optimum coagulant dosage, and minimize the need for jar testing.
