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.

Iron

An element often found dissolved in ground water (in the form of ferrous iron) in concentrations usually ranging from zero to 10 ppm (mg/l). It is objectionable in water supplies because of the staining caused after oxidation and precipitation (as ferric hydroxide), because of tastes, and because of unsightly colors produced when iron reacts with tannins in beverages such as coffee and tea. As little as 0.3 ppm of iron can cause staining. (See also ferrous iron, ferric iron, and heme iron).
