The HydroACT Analyzer with DuraTrac 4 Streaming Current Sensor is Chemtrac’s most reliable and accurate Streaming Current Monitor, providing unique and versatile capabilities for optimizing coagulant or polymer dosing. With improved Streaming Current measurement capability, expansive I/O, state of the art chemical feed logic, and the ability to monitor additional parameters key to coagulation (e.g. pH, UV254, NTU), this revolutionary product offers a dependable, comprehensive, and scalable approach for tackling virtually any water treatment scenario. A well designed interface gives the user easy access to frequently used features like zero offset. Intelligent diagnostics, service reminders, advanced alarm features, and optional email/text alerts all work together to notify the user when service is required or when process conditions having changed sufficiently to warrant attention.
The HydroACT Streaming Current Analyzer standard configuration includes version HA2 analyzer, 1 DuraTrac 4 sensor, 1 analog output, and 25 feet of interconnect cable. Optional features include relays, digital inputs, digital communications, expanded number of sensor inputs and analog outputs, color display, and data download capability.

The Georgia Rural Water Association held their 40th Annual Spring Conference at the Jekyll Island Convention Center May 7-9, and Chemtrac was there. In fact, this was the 34th year that Chemtrac exhibited at the conference. 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. 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. 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. 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. The Lab Charge Analyzer will be featured at the Chemtrac Booth (#2025) during the upcoming AWWA ACE17 conference and exhibition, June 11-14. 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).

Not Just Streaming Current Measurement Anymore
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.
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.
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.
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.
