✦ Synopsis

SUMhffLRY

The first seawater desalination plant by electrodialysis in the world started its operation in September, 1974 at Noshima island of Hofu city, Yamaguchi Prefecture, Japan. The capacity of the plant is 120 m3/day and the plant has been supplying fresh water from the sea for the 800 inhabitants of the island. Batchwise operation is utilized to simplify the process because of its relatively small capacity, but the operation is fully automatic to supply fresh water continuously using a storage of proper capacity_ The water cost is relatively high but lower than that of conventional distilIation processes of the same capacity_

INTRODUCIXON

There have been a number of electrodialysis plants all over the world which desalinate brackish or saline water to get fresh water. Electrodialysis has been
