| Proven Technology |
Toray has completed the development of the "Brine Conversion
2-stages Seawater Desalination System", called "BCS".
A pilot plant is operating successfully at Toray's Ehime plant site
since 1997. The first commercial plant of 1500 cbm/day (400,000 gpd)
is operating successfully since March 1999 in Gran Canaria / Spain.
These experiences led to commercial installations at Tortola / British
Virgin Islands, Curacao / Netherlands Antilles and another expansion
at Gran Canaria / Spain. |
| Advantages of
High Recovery Ratio |
| Plants recover 60% fresh water, which is 50% more efficient
than conventional SWRO systems. |
 |
| Remarkable Technological
Achievments |
The process is based on two major
technological achievements:
- The high pressure resistant RO membrane element - Optimized
system engineering |
 |
|
| Slashed Operating
Cost |
With a 60% recovery system, the size of the following
components will be reduced.(compared to a conventional system)
| - Seawater intake |
(to 2/3) |
| - Pretreatment |
(to 2/3) |
| - High pressure pump |
(to 2/3) |
| - Brine discharge |
(to 1/2) |
Thus, investment cost can be reduced by 15-20%,
operating cost by 15%. |
