PURE WATER OCCASIONAL

The Pure Water Occasional is a free email newsletter about water and water treatment. This website acts as an archive for early back issues of the newsletter plus a holding place for articles about water contaminants and treatment methods, "how to" articles about water treatment, links to equipment manufacturers' websites, a glossary of water treatment terminology, and more... The How It Works series examines familiar but sometimes misunderstood devices used in water treatment. If you've ever wondered how a reverse osmosis unit, or a permeate pump, or an air gap faucet works, this is the place to look.
