The Puretec ROS2700 Series features continuous-flow water production and operates on line pressure, which eliminates the need for an electrical booster pump in most applications. It uses water pressure to reverse a natural physical process called osmosis. Water under pressure is forced through a semi-permeable membrane to filter out minerals and impurities. The treated water goes to the faucet; minerals and other impurities are sent to the drain with RO waste water. The patented high-production, low-energy membrane purifies up to 2,725 litres (720 gallons) of water per day!
