SURSORB GAM is an impregnated granular activated carbon designed for removing basic gases such as Ammonia (NH3). In addition, the product retains an appreciable capacity for VOCs and other organic contaminants. SURSORB GAM carbon neutralizes the caustic nature of Ammonia (NH₃) using simple acid/base chemistry. The final reaction product is then stored in the pore structure of the activated carbon.  Its base material is manufactured by activating coconut shell charcoal at high temperatures by steam.
