With fresh water less and http://www.filmusa.org/canadian-online-pharmacy-levitra less at the ready, desalination technology ideas are gaining popularity. Researchers at the
De-chlorination is order viagra or levitra one of the more annoying parts of the desalination process, eating up time and money as chlorine is added to seawater to disinfect it and prevent the levitra delivered overnight formation of a biofilm that decreases the efficiency of the polymide membrane through which the water is filtered. But chlorine damages this membrane, so the membrane deteriorates after repeated use. So water has to www.velikibrat.us be chlorinated, then de-chlorinated, then filtered.
The new membrane is made of www.strattonpublishing.com sulfonated copolymers that are not harmed by chlorine, so it stays effective all through the process. Using these will make the desalination process much cheaper through higher productivity and energy efficiency. And reducing the cost of the process is exactly what is needed to make fresh water more available. Good news for investors and thirsty people.
