The membrane processes have greatly <br />broadened the horizon of possibly economic utilization of brackish waters <br />for industrial and municipal use, Membrane processes can also be used in <br />some cases for purifying waste streams to meet pollution control standards, <br />and for industrial separation such as the recovery of alcohol from a dilute <br />water stream, A combination of ~embrane and distillation processes can <br />be used to meet stringent water discharge regulations, such as the zero- <br />discharge regulations applying to electric power plants located in the <br />Colorado River Basin, <br /> <br />The figures and charts that follow are intended to summarize my pre- <br />sentation, and to serve as memory joggers if they are referred to in the <br />future. They summarize the principles underlying the various desalination <br />processes, their areas of application, their problems and their costs, In <br />addition, some tables have been included to indicate the size of desalination <br />developments in the world; these tables attest to the technical and commercial <br />feasibility of desalination plants for those situations where it is an <br />economic solution to a local water supply problem, <br /> <br />2 <br />
