✦ Synopsis

The problem of potable water shortage in some of the islands and coastal areas of India has led to consider sea water desalination for potable purposes . One of the membrane processes, namely, the electrodialysis(ED) has been designed and fabricated to meet the demand of a section of the population of Kavaratti island (Lakshad% eep, Union Territory) . The plant having a capacity of 5 .5 m /day is based on two stage reduction of salt wherein the first stage reduction upto 85% is achieved by recirculation of sea water .

The plant commissioned in February, 1989 is running satisfactorily to its rated capacity .

Useful information obtained during the period of first one year is reported here . A novel method of preventing scale formation and other salient features are brought about . An awareness is being created to go in for such plants in near future based on the performance of the above_ first experimental unit .
