Granular Activated Carbon - Acid Washed is made from selected bituminous coal to insure positive quality control during the manufacturing process. Virgin raw material is activated thermally in a rotary kiln steam atmosphere. By maintaining high quality control standards, the customer is able to anticipate high adsorption of their molecular impurities. The finished product is acid washed and dried to remove any trace of impurities.
