Chemtrac Exhibits at WEFTEC with other NAF Companies
For the second year in a row, Chemtrac joined four of their North American Filtration (NAF) sister-companies in exhibiting in a combined booth at WEFTEC. The other NAF subsidiaries were: NEFCO, Mass Transfer Systems, Sanborn Technologies, and LEEM Filtration. The event took place at the Ernest N. Morial Convention Center in New Orleans, October 1-4, 2018.
Keeping up with the Probe & Piston
In order to get the most out of your Streaming Current analyzers, it is imperative to keep up with any maintenance needs for the probes and pistons. This means periodic cleaning and eventual replacement. We have posted four new “How-to Videos” to help out when it is time to clean, or replace, the probe and piston.
Chemtrac Products Featured in January Issue of TPO
A case history that was first introduced as a testimonial video on our website, has now landed in print on the pages of TPO (Treatment Plant Operator) magazine.
Come See us at WEFTEC
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.
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.
Not Just Streaming Current Measurement Anymore
Working closely with a major municipality in the southeast, Chemtrac, Inc. compared their new line of coagulation control instrumentation against their tried and proven Streaming Current Controller (which has been in use at this specific plant for the past couple of years).

SC Water Treatment Plant Overcomes Challenges due to Epic Flood
In October, 2015, the city of Columbia, SC received about 24 inches of rain in 48 hours. Severe flooding occurred. The storm had an impact on the Broad River, and subsequently created challenges for a local water treatment plant.
DuraTrac 4 Seal Kit Maintenance
This video shows how to adjust, maintain & replace the seals used on the DuraTrac 4 Streaming Current Sensor. Also, it will show you how to resolve any leaking that may occur from the bleed hole on the probe block.
Cleaning the Chemtrac DuraTrac 4 Sensor Probe and Piston
Periodically the Streaming Current Sensor will become less responsive, and when this happens, the probe and piston should be cleaned. The cleaning alone can restore the sensor back to where it is once again delivering expected performance results.
Changing the Piston in the Chemtrac DuraTrac 4 Streaming Current Sensor
Over time, the probe and the piston in the Duratrac 4 Streaming Current Sensor will become worn, and subsequently less responsive. When this happens, cleaning the probe and piston surfaces may not be enough to improve the response to a degree of satisfaction.
