Sasakura is the world’s leading manufacturer of desalination plant. An independent survey published in 2004 shows that more than 10% of the total installed capacity of thermal and membrane plants in the world has been supplied by Sasakura and its licencees. The Sasakura experience covers so many desalination processes in every possible application : land based municipal plants, packaged plants for construction and hotel use, marine and offshore units, plants for making boiler feed and process water, dual-purpose combinations with electricity generation, miniature watermakers for fishing vessels and hundreds of other applications.
Through more than 40 years of activity in the field of desalination, Sasakura has gained experience both as main contractor and as a joint venture partner for dozens of multi-million dollar turnkey projects around the world. The arrangements have sometimes included occasional long-term operation of the plants themselves. Nothing is too big or too small for Sasakura to tackle.
Furthermore, due to the technological know-how developed over the years, Sasakura has accumulated a vast experience enabling diagnostics to be performed on older desalination plants and has restored full recovery of performance to various plants throughout the world.
The Multi-Stage Flash-type plant is the most common type of desalination plant .
It is used particularly for large scale applications that are combined with power generation.
Sasakura is proud to be the leading supplier of this type of plant.
Sasakura’s RH is the most perfect process amongst sea water desalination plants because it achieves the high GOR by “re- heating” the vapour produced in the lower temperature chamber using a thermo compressor and realizes the lowest electric power consumption.
Furthermore, it operates with low temperature – less than 70 °C – thus preventing scaling formation.
The equipped blower contributes to increase the temperature of the vapour produced and can serve the heating medium of the seawater evaporation. In this way, most of the heat is effectively recycled in the continuous evaporation/condensation process.
Reverse Osmosis Desalination Plants produce fresh water by utilizing semi-permeable membranes which effectively resist the passage of dissolved salts. From the energy saving point of view, this type of desalination is the best.

Based on the Sasakura’s long term accumulation of the professional technology in the field of desalination plants, sasakura’s rehabilitaiton covers the plants supplied by the other manufacturers too.
