Electrokinetic Charge Analyzer & Titrator

ECA 2100 / ECAT 2100

An essential tool for any water treatment professional, the ECAT2100 Charge Analyzer/Titrator enables operators to perform a virtually “hands free” test for finding the optimum coagulant dosage much faster than conventional jar testing. A simple touch of the key-pad and the instrument automatically titrates to the isoelectric (neutral) charge value, or other desired endpoint. A graphical display allows real time observation of the titration curve, and the data can be downloaded to a PC for historical record keeping.

  • Laboratory-Charge-Analyzer-2Tennessee 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. 

  • franklin-thumbnailNew 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.

  • IWC_BannerChemtrac 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-Booth2WQTC 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. 

  • lake-lanier-grwa-conferenceOptimizing Coagulation at GRWA Fall Conference Posted on: 10/28/2014

    The Georgia Rural Water Association Fall Conference is taking place at Lake Lanier Islands, October 26-29. Mark Vandiver will make a presentation highlighting the use of the Chemtrac CCA3100 Coagulant Charge Analyzer for optimizing coagulation in water treatment plants.

    The CCA3100 is a laboratory instrument that allows for coagulant dose determination in a much simpler and quicker fashion than using traditional jar tests. In fact, finding the appropriate dose can take less than five minutes.
