AWWA B100-01

This standard covers gravel, high-density gravel, silica sand, high-density media, anthracite filter materials, and the placement of the materials in filters for water supply service application. A planned revision to ANSI/AWWA B604 Standard for Granular Activated Carbon will address the use of GAC as a filter medium and as an adsorbent. The purpose of this standard is to provide purchasers with a standard for purchasing and installing filtration materials; it is not intended as a guide for filter design. The major revisions in this edition of ANSI/AWWA B100-96 include the following: the format has been changed to AWWA standard style; the acceptance clause (Sec. I.C) and definitions (Sec. 3) have been revised to approved wording; dicussion of a potentially new anthracite standard is included; addition of reference to a planned revision of ANSI/AWWA B604 for use of GAC as filter medium; addition of high-density sand and gravel media; revision to delivery and bulk shipment requirements; adoption of an alternative test for large-aggregate specific gravity; addition of in-place media sampling; and, substitution of ASTM C128 for ASTM C188 as the standard specific gravity test of fine aggregates.
