Pure Aqua designs complete water filtration systems as well as reverse osmosis water systems. In December 2013, a reverse osmosis water system was supplied to a major company in Sri Lanka. The system included five reverse osmosis systems selected from our RO-200 series, seven chemical injection systems for pretreatment, and ten multimedia filters selected from our MF-400 series. The identical reverse osmosis systems can produce 4,500 GPD of purified water from a municipal tap water feed.
