Total Organic Carbon or TOC is a measurement of the amount of organic carbon present in water. TOC can be measured in real-time, without reagents, with our TOC analyzer to improve water and wastewater process control and plant efficiency.
IMPORTANCE OF TOC FOR DRINKING WATER AND PROCESS WATER
In the drinking water industry, Total Organic Carbon is an important parameter that is often used as a general indication of water quality. Strict regulations are applied in many countries as elevated TOC levels have been directly associated with increased disinfection by-product (DBP) formation in the treatment process and bacterial regrowth in the distribution systems. In the United States, the Environmental Protection Agency (EPA) Stage 2 DBPR has set requirements for TOC removal based on source water characteristics.
TOC is also used in the industrial sector as a general water quality index and indicator of contamination.
DELAYED LAB RESULTS LIMIT ACTION
Relying on grab samples leads to significant delays. When results come back from the lab, the information is usually of little value for process control and improving plant performance. The most common methods for Total Organic Carbon analysis are Method 415.1 (Combustion or Oxidation) and Method 415.2 (UV Promoted, Persulfate Oxidation). The test involves converting all organic carbon in a water sample to carbon dioxide (CO2) by utilizing heat and oxygen, chemical oxidants or UV radiation. The resultant CO2 concentration is measured with an infrared analyzer and reported as organic carbon (mg/L). The test takes 5-10 minutes to yield results in the lab, with continuous reagent-based on-line analyzers also available.
