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.
