ANSI/AWWA B604-12

This standard describes virgin granular and extruded activated carbons for use as a filter medium and adsorbent in water treatment. It involves the selection, placement, and use of granular activated carbon (GAC) in filter adsorbers where the GAC must function as filter medium and adsorbent, as well as in those systems where the primary function is adsorption. Major revisions made to the standard include the following: added an alternative procedure for determination of percent moisture (Sec. 5.2.3.3); added security requirements for bulk shipments (Sec. 6.2.6); added a mandatory requirement for delivery of Affidavit of Compliance (Sec. 6.3); and, Filter Material and Placing and Preparation was moved to appendix C.
