  • Ultrafiltration Systems – Membrane Solutions

    Reverse osmosis (RO) is a pressure driven membrane separation process that separates dissolved and suspended substances from water. The membrane acts as a selective barriers, removing unwanted substances such as salt, producing water safe for drinking. Method: In this process, pressure (of the order 15 to 40 kg cm^2) is applied to impure water to force its pure water out through the semi-permeable …
