A new practical method for disinfecting drinking water has been developed using anelectrodialysis system with cation-and anion-exchange membranes. The effectiveness of the current densities and flow rates of river water containing bacteria cells passing through a desalting chamber has been studied for practicality.
Perfect devitalization of Tamagawa River water is possible using an electrodialysis system with a current density of 0.48 A·dm-2 and a flow rate of 0.6dm3·min-1, and which consumes 7.92 KWH per 1m3, Therefore, the cost of this system is about 160 yen per 1m3 which is slightly more expensive thanthe chlorine disinfection method.
