What is Total Organic Carbon in Drinking Water?

Total Organic Carbon (TOC) in drinking water is formed from the decay of naturally occurring organic matter (NOM) or man-made organic chemicals. TOC is an important water quality parameter for drinking water plants due to its link to disinfection byproducts (DBPs). TOC alone is not harmful, but upon its reaction with a disinfectant, it can produce harmful byproducts. Regulations like the USEPA’s Safe Drinking Water Act attempt to balance the risks presented by microbial pathogens and byproducts from the disinfectant used to destroy these microbes. DBPs, such as haloacetic acids (HAAs), continue to form as water passes through a plant’s distribution system, and contact time increases. Trihalomethanes (THMs), another class of DBPs that include chloroform, are formed from the interaction of TOC, naturally occurring bromide, and chlorine.

Sievers Membrane Conductometric Technology

Sievers Membrane Conductometric technology uses a gas-permeable membrane to selectively pass only the COproduced from the oxidation of organics. This prevents acids, bases, and halogenated compounds from interfering with the conductivity measurement from oxidation, thus preventing false high or false low TOC readings.
