Activated Carbon (AC) is similar to ion exchange resin in density and porosity. It adsorbs many dissolved organics and eliminates chlorine or other halogens in water. It does not remove salts. Activated Carbon is a low-cost method available to remove low-molecular weight (<100 MW) organics and chlorine. The system includes three items: a media tank, activated carbon, and a valve or controller.

The media tank is filled with granular activated carbon media, which is made of organic material such as bituminous coal, coconut shells, and pecan shells that have been exposed to excessive temperatures. As suspended solids accumulate in the carbon bed from incoming water sources, the media must be backwashed to expose new areas for the adsorption process to occur and to avoid unwanted "channeling" effects. New carbon is required when existing media can no longer eliminate unwanted organic materials.

Typical applications for Activated Carbon systems include:

• Reverse Osmosis Pretreatment
• Boiler Feedwater Treatment
• Reagent Grade Laboratory Water Systems
• USP Purified Water Systems
• Hemodialysis Water Systems
• Commercial Water Systems
• Food and Beverage

The Biolab Equipment™ TAFC – 1" and 2" Series Activated Carbon Filters are designed to eliminate color, odor, and/or toxicity primarily chlorine and chloramines from incoming water. Our complete systems feature either the Performa™ Valve for 1" flow or the Magnum IT™ Valve for 2" flow ranging from 3 to 60 USgpm. Each system offers the user with simple operation and efficient backwashing. Single, duplex twin alternation or parallel configurations are available.
