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.

Whenever workers enter a vessel containing carbon, all precautions must be taken since dangerously low levels of
oxygen may be encountered. Atmosphere sampling and work procedures for potentially low oxygen areas should be followed.
