Come See us at WEFTEC (Booths 1841 & 1844)

Chemtrac is in Chicago this week exhibiting at WEFTEC along with a few sister companies: NEFCO, Mass Transfer Systems, LEEM Filtration, Mer-Made Filter, and Sanborn Technologies. We are all owned by our parent company, North American Filtration, and we are sharing one 20’ x 50’ booth....

Video Testimonial: Lab and Online Charge Analyzers for Challenging River Water Coagulant Dosing

The water treatment plant in King, NC has a source water that is quite a challenge to treat. The Yadkin River can experience quick and substantial changes in turbidity (NTU) and organics (TOC). Subsequently the required chemical feed dosages can be significantly impacted in a short period of time. Looking for the appropriate technology to help optimize their coagulation, settling, and filtration process, allowing them to produce the best water for their customers, they turned to two products from Chemtrac: the Laboratory Charge Analyzer (LCA), and the online Streaming Current Charge Analyzer (HydroACT Analyzer, and the DuraTrac 4 Streaming Current Sensor)....

Chemtrac to Exhibit at ACE17 in Philadelphia

The Lab Charge Analyzer will be featured at the Chemtrac Booth (#2025) during the upcoming AWWA ACE17 conference and exhibition, June 11-14. The LCA allows for a target coagulant dose to be automatically determined in just a matter of minutes. Chemtrac will also have on display variety of analyzers including their on-line Streaming Current Monitor, particle counters, and reagentless chlorine analyzers. If you are going to be in Philadelphia for ACE17, please make it a point to stop by Booth 2025....

Another Successful Showcase at ACE 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....

Happy Birthday Chemtrac, Inc. — Thirty One-derful Years!

Founded in 1985 upon the release of a new Streaming Current Monitor, Chemtrac has come a long way and is now recognized as one of the world’s leading manufacturers of Streaming Current Monitors and Particle Counters, as well as the provider of the HydroACT series of multi-parameter analyzers....

Less Sludge Means More Money

“When Tennessee-American Water purchased Whitwell’s system we inherited an inefficient sludge removal and disposal process, and until we can implement a more cost effective way of disposing our sludge we greatly reduced current costs.” – Operations Supervisor, Michael Griffith Facing stringent water quality goals, water treatment plant operators hate playing “catch-up” while watching the sedimentation basin turbidity rise along with filter effluent.  Standard operating procedures amongst operator’s would agree that a little overfeed in coagulant is easier on daily operations than trying to underfeed especially when the coagulant choice is a PACl.  A proven alternative to this SOP is to use streaming current measurement to continuously monitor the charge demand of the raw water and th...

Removing Iron and Manganese in less than 10 minutes

Routine cleaning is essential for a streaming current monitor to work properly.   Therefore, plant operators desire a unit that is easy to clean, uses a good cleaning agent, and has a quick recovery of the streaming current reading after the cleaning is complete.   A 1:1 solution of hydrogen peroxide (approx. 5%) and acetic acid (common household vinegar) offers plant operators a simple and safe alternative to harsh cleaners.   A simple spray bottle and brush are all that is needed for a cleaning that takes less than 10 minutes to dissolve iron, manganese, and permanganate stains from the flow cell. Cleaning Steps: Remove probe, piston and flow cell from the SCM. Spray these pieces with 1:1 solution and allow the solution to set for a couple minutes. Brush the probe and piston before reass...

AWPCA Annual Conference in Huntsville Alabama, August 3-5

Chemtrac Inc will exhibit and present at the AWPCA (Alabama Water and Pollution Control Association) Annual Conference in Huntsville Al, August 3-5 2015.  Presentations include an “Update on Laboratory Charge Measurement and Advances in Streaming Current Measurement” along with “Mythbusting Filter Performance with Particle Counters and Turbidimeters. ...

Chemtrac Presenting at International EPRI Conference

John Clark and Joe Zimmerman of Chemtrac, Inc., will team-up to present a technical paper at the Eleventh International Conference on Cycle Chemistry in Fossil and Combined Cycle Plants with Heat Recovery Steam Generators. The conference will take place in St. Louis, July 14-16, and over 150 power plant chemists and engineers from around the world will be in attendance. Clark and Zimmerman collaborated with Luis Diaz and Phil Maszak of Florida Power and Light to author the paper, “The Quest to Monitor Corrosion Product Transport in the Power Plant Steam Cycle.” Particle detection and turbidity measurement are discussed; and a case study is included profiling a corrosion product study that was completed at the FPL West County Energy Center. The Chemtrac PC3400 Particle Counter, as well as t...

5 Minute Jar Test on Display at ACE15 in Anaheim

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. ...

2015 ARWA 37th Annual Technical Training Conference

Attendees of the Alabama Rural Water Association’s Annual Technical Training Conference were able to learn of the advantages of streaming current monitoring while visiting the Chemtrac booth.  Sporting a serviceable probe that the factory can rebuild, a higher flow capacity to minimize sensor fouling, and a more robust drive motor, Chemtrac’s DuraTrac 4 sensor is raising the bar for on-line streaming current measurement.  The HydroACT 600 controller accepts up to six sensors for measuring such parameters as streaming current, pH, chlorine (free or total), ORP, particle detection, and UV-254 organics measurement....

Tennessee Closes the Gap in Operator Training

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. ...
