Abstract

An industrial unit which optimizes the parameters of the electrodialysis process has been developed at the Research & Development Authority. The total energy requirement with this unit is about 1.2 kWh/m³ for brackish water of 2400 ppm and 3.3 kWh/m³ for water of 5000 ppm. For sea water desalination the system may be optimized by operating it with thin cells (0.4 mm) and thin polyethylene membranes (0.1 mm). In such a system the energy requirement for the desalination of sea water will be 12 kWh/m³ for operation at 20° C and 6.7 kWh/m³ at 70° C.
