THM Analyser

Parker's THM Analyser is an easy to operate, integrated Purge-and-Trap Gas Chromatograph (GC) that measures THM concentration in water at ppb levels in less than 30 minutes right at your own facility without tedious sample preparation. This integrated system is a powerful new tool that can help operators optimize water treatment at the plant to ensure regulatory compliance and evaluate water age in the distribution system for improved control over the formation of THMs. Simply collect a sample and connect it to the analyser sparging system. Then push the start button to begin the measurement cycle. Individual and total THM information is displayed clearly on the analyser touchscreen and laptop display. Analytical results, including measured concentration and detailed chromatography data are automatically archived for future review. The data may also be transferred to other software packages for more detailed trending analysis of THM information.

First UK water company to adopt Parker’s real-time analyser technology 

Posted by KC Staff

Until now, Anglian Water has relied on a laboratory for THM analysis. The company decided to look for an alternative onsite method which would take pressure off its laboratory and deliver a same-day result.

During the last five years, the company has invested more than £100 million in drinking water improvements, surpassing some of the most stringent quality targets in the world.

In July 2015, Anglian Water took the strategic decision to further enhance its water treatment and...
