Watergy | 47 followers on LinkedIn. Watergy is a start up that focuses on bringing cutting-edge research progress to people. In particular, we are struggling to set up some demonstration pilot plants for arsenic decontamination through tertiary photocatalytic treatments that could be cost-competitive and more efficient and reliable than common ionic-exchange resin adsorption treatments. Our technology requires no spare parts, is easy to maintain, long lived, and reliable.
