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.

Alkalinity

Alkalinity means the buffering capacity of water; the capacity of the water to neutralize itself. It prevents the water pH levels from becoming too basic or acid. It also adds carbon to water. Alkalinity stabilizes water at pH levels around seven; however, when the acidity is high in water, the alkalinity decreases, which can harm aquatic life. In water chemistry, alkalinity is expressed in ppm or mg/L of equivalent calcium carbonate. The total alkalinity of water is the sum of all three sorts of alkalinity; carbonate, bicarbonate and hydroxide alkalinity.
