WQA Developing Electrochemical Demineralization Standards
These systems show promise as a salt-free alternative to water softeners
The Water Quality Assn. (WQA) is currently developing a certification standard for electrochemical demineralization treatment. These systems show promise as a salt-free alternative to water softeners, according to the WQA.
In order to qualify against the standard, the electrochemical treatment system must reduce hardness as well as total dissolved solids. Like water softeners that are certified to NSF/ANSI 44 for the reduction of hardness, certified electrochemical demineralization devices will remove the calcium and magnesium that cause scale and must be designed for use in hard water. Pilot testing of the standard will begin this fall.
WQA members are welcome to participate in the development of this standard by joining the task force.
