4 History of Reverse Osmosis In the late 1940s, researchers began examining ways in which pure water could be extracted from salty water. During the Kennedy administration, saline water conversion was a high priority technology goal - "go to the moon and make the desert bloom" - was the slogan. Supported by federal and state funding, a number of researchers quickly advanced the science and technology of sea water conversion, but UCLA made a significant breakthrough in 1959 and became the first to demonstrate a practical process known as reverse osmosis (RO).

6 History of Reverse Osmosis In 1960, as head of the Saline Water Conversion Laboratory, Joseph W. McCutchan led a small pilot-plant group for development of reverse osmosis using the new UCLA membranes. The outgrowth of that project was the successful construction and operation of a reverse osmosis plant in the California town of Coalinga. This facility, the world's first commercial RO plant, which began operation in 1965, produced 6000 GPD of permeate water from brackish water. Water Equipment Technologies

7 Reverse Osmosis Basics Feed: Raw or pretreated solution entering a membrane system. Permeate: The high purity water which passes through the semi-permeable membranes and exits from the pressure vessel. Reject (Concentrate: blowdown: Brine: Waste): Normally, the waste stream from reverse osmosis which contains most of the dissolved solids in the feed in a concentrated form. Water Equipment Technologies

8 Reverse Osmosis Basics Recovery: The ratio of permeate produced divided by the amount of feed water used to produce the permeate. TDS: Total Dissolved Solids, expressed as parts per million (ppm). Parts per Million (ppm): A measure of proportion by weight, equivalent to a unit weight of solute per million unit weights of solution. Water Equipment Technologies

9 Reverse Osmosis Basics Milligram per Liter (mg/l): A weight-volume measurement which expresses the concentration of a solute in milligrams in a liter of solution. When specific gravity is unity, mg/l = ppm. Micron (μ): 1x10-6 meters or meters. Brackish Water, slightly, moderately, Highly (BWRO) Water with Salts, 1K PPM, 1K to 3K, 3K to 10K, 10K but less than Sea water at 35K to 45K (SWRO) Water Equipment Technologies

10 Reverse Osmosis Basics GPM: Gallons per minute. GPD: Gallons per day. MGD: Million gallons per day. CMD: Cubic meter per day. Water Equipment Technologies

11 Reverse Osmosis Involves Application of pressure greater than osmotic pressure of solution Diffusion of water but not salt through a semipermeable membrane in direction opposite of natural osmotic flow Water Equipment Technologies
