Work to Begin on New Standard: AWWA B1RI, Regenerable Ion Exchange Treatment

The AWWA Standards Council is happy to announce that work on a new standard has been authorized and is now beginning on the development of the following:
AWWA B1RI, Regenerable Ion Exchange Treatment

This standard describes ion exchange (IX) resin for water supply service applications and the requirements of the equipment used in water treatment to remove target constituents such as nitrate, hexavalent chromium, softening, iron, manganese, radium, uranium, arsenic etc., for potable water treatment applications with regenerable ion exchange resin (resin regenerated co-currently, counter-currently, or fluidized bed.) It discusses the design of regenerable ion exchange resin system equipment, requirements for the ion exchange material, and startup and troubleshooting. This is focused on drinking water municipal applications, and not point-of-use nor point-of-entry systems for residential use.  It also does not intend to be a standard for non-potable applications.

New standard B1RI has been assigned to the existing Standards Committee on Ion Exchange. Please contact Liz Ralph (lralph@awwa.org) if you would like to participate or if you have any questions about the work on the new standard.

Publication of this information constitutes public notice of work initiated in conformance with the AWWA Standards Program Operations Procedures (SPOP) and the requirement of the American National Standards Institute (ANSI).
