Reverse Osmosis (R.O.) Reverse Osmosis (R.O.) is a modern technique for water purification derived from the natural biological cell operation, which drives the transport of nutrients in plants and animals. The process produces pure water on a continuous basis, in a large (but reliable) quantity. With reverse osmosis, only one process is needed for the physical and chemical purification of water. This is a continuous pressure driven process for which no chemical additions are required. Dissolved materials are separated from the water by means of a semi-permeable membrane. Modern membranes can remove up to 99% of dissolved matter without any addition of chemicals and without frequent shut downs for regeneration. Water produced by means of R.O. contains virtually zero dissolved solids. The Reverse Osmosis procedure removes: |Click here to go back to previous page|
