✦ Synopsis

This study has been made for rhc purpose of grasping the o-on characlcris~ics of the clec-trodiai+ plants and evaluating their economy. The wsults awms follows:

1. The desalting of sea wakr for obtaming fresh wa1cr of 150 ppm as Cl-was wc+ with much 10-r energy consumption. 22.7 kWh'm3.

2. Throughout the continuot&operarlon no troubles H~CC CRcwntercd.

3. It was prowif that rht process tcsred was more economicA than the evaporation process \hcn used in a smA capx?t, dc=tting plans in special environments such as on ships and iriands.

At the present moment. Japan is not in a position to promote operation of sea water conversion plants on an industrial basis.
