Desalination of agricultural drainage water

Abstract Desalted agricultural drainage water may offer a secondary source for potable water in the next years to cope with water needs in arid areas. The proper selection of the desalting scheme and its design as well as operational features is mandatory for the economic utilisation of this potential water source. The present paper firstly outlines the rational approach for selecting the desalting system based on technical and economic considerations. Secondly, a computer software based on a modified short-cut method for reverse osmosis (RO) system design has been developed. Finally, the results obtained by application of the developed software for the design of a typical RO desalting facility have been discussed.
