✦ Synopsis

The distillation test plant operated since April 14, 1972 during 94.2% of the work day has the capacity to treat 1,000 cu. meter/day of sea water, to produce 850t of fresh water of excellent quality, leaving 150t of concentrated brine containing 20% solid matter . Raw sea water was pretreated to prevent scale formation and corrosion of materials in distillation. Patents have been granted in Japan, USA, United Kingdom, West Germany, France, Italy, etc. (1).

This method enables use of a base metal such as common steel for construction with the following advantages :

Capital investment is cheaper.

No galvanic corrosion arises . Mechanical structure is rigid . Contamination of poisonous heavy metals is avoidable . Upper limit of temperature is higher . Amount of raw sea water is smaller. Amount of exhaust brine is smaller.
