Laboratory Charge Analyzer
LCA-01 / LCA-02 / LCA-03
The Laboratory Charge Analyzer (LCA) is an essential coagulation optimization tool for the water treatment professional. The LCA allows the user to determine the ideal coagulant dosage needed to achieve optimum NTU and TOC reduction in less than 5 minutes typically. The LCA can also be used to determine the dosage rate of additives like lime or caustic when used to raise coagulation pH of low alkalinity waters. The larger sample size capability of the LCA allows the user to accurately titrate samples using undiluted coagulant, which is a very important feature when working with highly reactive coagulants like PACl or ACH. Options for pH measurement and auto-titration are also available.
The Laboratory Charge Analyzer (LCA) is an essential coagulation optimization tool for the water treatment professional. The LCA allows the user to determine the ideal coagulant dosage needed to achieve optimum NTU and TOC reduction in less than 5 minutes typically, earning it the moniker “5 minute jar tester”. The process of finding the optimum dosage simply involves feeding in a measured volume of coagulant into the raw water sample until the reading on the LCA indicates complete charge neutralization has been obtained. Some pH adjustment may be required to achieve accurate test results. An option for pH measurement allows the user to also quickly determine the dosage rate of additives like lime or caustic when needed to raise the coagulation pH of low alkalinity waters. Titration of the coagulant and pH adjustment additives can be performed manually using the LCA-1, or with the touch of a button using the autotitration features that come standard on models LCA-2 and LCA-3. The automatic titration feature further simplifies the testing process and helps ensure the most accurate results possible. Another very important feature is the large sample size capacity which allows the user to accurately titrate samples using undiluted coagulant (requires micro-pipette), which is the recommended method when feeding PACl or ACH. Chemtrac’s Laboratory Charge Analyzer comes backed with 30 years of charge analysis expertise and world class customer support.

The Laboratory Charge Analyzer Model LCA-3 is Chemtrac’s newest model lab unit capable of performing automatic titrations to determine optimum coagulant dosage of a raw water sample. The LCA-3 is also capable of determining the amount of pH adjustment chemical, such as lime or caustic, that is needed to maintain optimum pH conditions for coagulation. In this video, a sample of water with high color and low alkalinity is being tested. A 1% aluminum sulfate solution is used as the coagulant (titrant) for determining the ppm dose required for charge neutralization, and a 0.5% caustic solution (NaOH) is used as the pH adjustment titrant.
- Chemtrac to Exhibit at IWC in San Antonio Posted on: 11/03/2016
The 77th Annual International Water Conference will be held November 6-9 in San Antonio, TX. The IWC remains the premier source of technical information and training in the industrial water and wastewater business, spanning numerous industrial sectors, and addressing today’s most relevant technical topics. Chemtrac will once again be hosting a booth in the IWC Exhibit Hall.
- South Carolina WTP Overcame Flood-Related Challenges Posted on: 10/21/2016
It is not uncommon for water treatment plants to have to adjust coagulant doses when raw water conditions rapidly change due to passing storms. However, recent hurricanes and tropical storms remind us that when record-setting rainfalls cause epic flooding, water treatment plants can be faced with unprecedented challenges.
- Another Successful Showcase at ACE 2016 Posted on: 07/30/2016
The Chemtrac team joined attendees at ACE 2016 in Chicago, IL to discuss the latest models of Streaming Current Monitors, Particle Counters, Chlorine Analyzers, and HydroACT multi-parameter analyzer. The Laboratory Charge Analyzer, a bench-top streaming current unit, was the featured product.
As mentioned previously, the LCA builds on the success and solid performance of its predecessor models (CCA3100, ECA2100 and ECAT2100), allowing for charge neutralization titrations to accurately determine target coagulant dosages for surface water treatment. Essentially, the LCA provides a way for conducting jar tests in less than five minutes, as opposed to the traditional methods that can take in excess of an hour to run.
- Introducing Next Generation Products at ACE16 Posted on: 06/14/2016
We will be introducing our two new series of products at the 2016 AWWA Annual Conference & Exposition in Chicago next week (June 19-22). Both the Laboratory Charge Analyzers, and the third-generation HydroACT multi-parameter analyzers, will be revealed and on display at our Chemtrac Booth (#1040) in the ACE Exhibit Hall.
