The most effective filtration process for removing organic contaminants found in water. It works by attracting and holding certain chemicals as water passes through it. Because organic chemicals are usually responsible for taste, odor and color problems, carbon filtration can be used to improve "aesthetically objectionable" water. Carbon filtration is recognized by the WQA as an acceptable method to maintain certain drinking water contaminants within EPA limits.

A method of removing organic compounds and chlorine by-products from water using carbon's natural ability to adsorb these chemicals. The technique is often used to remove objectionable taste and odour from water.

(Water & Water Treatments) Carbon is an absorbent material and is extremely efficient at removing odours, taint and discoloration from tap water.  However, it in no way prevents the build up of hard water scale.

A method of removing organics and chlorine by use of carbon's natural ability to adsorb such chemicals.

a common water filtration method which uses activated carbon to adsorb contaminants
