In recent years, TOC has steadily gained in importance in both wastewater and drinking water analysis. In relationship to COD TOC provides specific information about the type and origin of organic loads in wastewater.
In drinking water production TOC is an important measurement for monitoring precursors to disinfection byproducts (DBP). TOC monitoring and removal are regulated by the US EPA. Hach TOC Method 10267 is approved for measuring TOC in drinking water.
Advances have also been made in TOC analysis – no longer is a major investment required, either financially or in terms of equipment. Reliable and cost effective TOC measurements are possible with the Hach TNTplus® Vial Test System.
