Municipal Drinking Water Plant Significantly Reduces Chemical Costs Using Sievers TOC Analyzer

BOULDER, COLORADO, September 5, 2007 — GE Analytical Instruments, a division of GE Water & Process Technologies and the leading global manufacturer of Total Organic Carbon (TOC) Analyzers, helped a drinking water plant in Englewood, Colorado optimize their chemical usage to save more than $55,000 in one year.

The Englewood plant installed a Sievers TOC Analyzer to monitor TOC, in compliance with the USEPA Disinfectants and Disinfection Byproduct Rule (D/DBPR). The D/DBPR attempts to limit exposure of harmful byproducts in drinking water that form from the interaction of a water source's naturally occurring organics, or TOC, and a municipal plant's disinfectant process. Most commonly, the process includes adding coagulants.

The plant used the TOC analyzer to continuously monitor their influent and effluent water TOC and adjusted their coagulation dosage rate accordingly. Because they gained instantaneous results from their TOC analyzer, rather than waiting for TOC results to return from the laboratory, they further decreased chemical costs and associated hauling costs.
