The State of Regulations

As the POU/POE water treatment industry progresses to new levels and meets new challenges, issues regarding regulations and standards continually arise. As the industry waits for the EPA and U.S. government to finalize regulations, the industry is forced to ride out the MCL changes, rule withdrawals and estimated costs that each proposal brings. Listed here is a review of regulation changes the industry has seen in the last year and a brief look at which ones to watch for in the future.

Desalination of Seawater Helps Meet Fresh Water Demand

Three French companies are meeting the water demands of large populations through the use of seawater desalination.Distillation and reverse osmosis are two competing techniques in the desalination of seawater. While each method has pros and cons, both provide a vital service in making seawater drinkable. Three French water companies (Saur, Degremont and Sidem) are working to improve the quality of fresh water created by both these methods and have invested heavily in the Mediterranean and Middle East markets with these technologies.

Reverse Osmosis Membranes Help Conserve Water At the Sydney 2000 Olympic Games

During the 2000 Olympic Games, U.S. Filter Australia/Vivendi Water supplied a wastewater reclamation plant that recycled sewage and rainwater runoff at the games site. Part of the purification process involved the use of reverse osmosis (RO) technology.

Seawater Desalination With Reverse Osmosis

Desalination technology has brought fresh water and hence industrial and commercial development to areas of the world that otherwise might have remained unproductive. Not only has development been enhanced by this technology but, more importantly, the health and welfare of many people have been improved by the supply of sanitary fresh water supplies.

Editorial: Home Buyer Awareness

I have started the new year on the right foot. I bought a house. I have spent many years day dreaming about my first home. The fireplace, staircase, patio, large kitchen, an office and my very own driveway ... which of course I will despise by the end of this harsh Chicago winter.
