AWWA B104-24 Single-Use Ion Exchange Treatment for Trace Contaminant Removal
The purpose of this standard is to provide the minimum requirements for purchasing and installing ion exchange resin and equipment, including physical, chemical, packaging, purchasing, shipping, testing requirements and installation.
Description
This standard describes ion exchange (IX) resin for water supply service applications and the requirements of the equipment used in water treatment to remove contaminants such as per and polyfluoroalkylsubstances (PFAS), perchlorate, hexavalent chromium, uranium, and radium, etc., for potable water treatment applications with single-use ion exchange resin (resin that is not regenerated nor fluidized bed.) It discusses the design of ion exchange resin systems and requirements for the ion exchange material. It is not intended to cover all media that work for listed contaminants, only ion exchange resin. This standard does not cover ion exchange resins that are regenerated on site.
This standard can be referenced in documents for purchasing and receiving ion exchange resin and equipment, and can be used as a guide for testing the physical and chemical properties of ion exchange resin media. The stipulations of this standard apply when this document has been referenced and then only to ion exchange resin media used in potable water treatment applications.
