Carbon Tetrachloride


Carbon tetrachloride is a volatile organic chemical (VOC). It is used in the manufacture of cleaning agents, solvents, fire extinguishers and chlorofluorocarbon. It has been found in significant amounts in water supplies in the United States.

 

Most VOCs are considered health risks, and many are known carcinogens. They are all man-made chemicals.

Carbon Tetrachloride is classed by the EPA as a probably human carcinogen. The MCA is only .005 mg/l.

Treatment: Carbon tetrachloride is removed well by activated carbon filtration. Like most VOCs it is best removed by carbon with a high micropore count. Coconut shell carbon is the carbon of choice with carbon tetrachloride and other VOCs.

Reverse Osmosis is a 70% to 80% remover of carbon tetrachloride.
