WC&P is proud to offer this comprehensive glossary to our readers and website visitors. This living document is intended to serve as an easy-to-use reference source for information on the POU/POE water treatment industry. 

 

Any suggestions or input that would further enhance or expand the glossary are strongly encouraged.

 

We would like to formally thank and credit such organizations as WQA, AWWA, WEF, Lenntech and other web glossary sources for providing some of the basis and background of this compendium.
