Air Stripper-  This technology is based on the principal of exposing a large surface area of water to air.  Water is pumped to the top of a tower and then cascades downward over a plastic packing material.  At the same time, filtered air is blown upward through the tower, removing or "stripping" any contaminants in its path.    

GAC Filter-  Removal of organic compounds with a granular activated carbon filter is based on the principle of adsorption.  The activated carbon's porous composition provides tremendous surface area that acts as an absorption system.  The water is purified as it passes through the carbon filters. The used carbon is replaced periodically according to industry standards.  GAC filters are similar to air strippers in that they both remove volatile organic contaminants.
