ideal carbon for general taste and odor removal, chlorine reduction, and the removal of a wide range of organic contaminants

Calgon®'s OLC 12x40 granular activated carbon (GAC) is a coconut shell derived carbon for the removal of dissolved organic contaminants from water, wastewater and process liquids. These contaminants include taste and odor compounds, chlorine, organic color, total organic carbon (TOC) and industrial chemicals such as chlorinated solvents (TCE, PCE). The pore structure enables it to be used for adsorption of both high and low molecule weight impurities from waters and liquids. The carbon is especially effective for adsorbing trace organic compounds such as vinyl chloride, methylene chloride, MTBE and THM's/disinfection by-products.

Calgon® OLC 12 x 40 is certified to NSF/ANSI 61 standard and complies with the requirements for activated carbon as defined by the Food Chemicals Codex (FCC) (8th Edition) published by the U.S. Pharmacopeia.
