develop unbalanced flow schemes to improve the
performance of RO desalination by increasing the
overall recovery of desalination RO systems and
transferring energy to the feed flow.
Any RO treatment alternative is a high-energy
solution compared to "fresh"
surface water or groundwater
treatment systems. However,

water applications where total
dissolved solids (TDS) are less
than 3,000 ppm. In contrast,
seawater typically has a TDS
content of approximately 32,000
ppm. The higher dissolved solids
content of seawater requires
much higher pumping pressure
to overcome the osmotic
forces. Seawater RO (SWRO)
typically operates at a pressure
of approximately 750-1,000 psi.
BWRO systems typically operate
at pressures less than 200 psi;
this lower pressure translates
to a much lower power cost. In
addition to the power savings,
BWRO has less waste product
produced per gallon of water
treated. BWRO typically rejects
about 20-30% of the raw water
produced in a waste concentrate stream, while
SWRO typically rejects up to 40% of the raw water
in the waste concentrate stream and pretreatment
operations.
The capital cost of desalination is project specific.
Many elements of the project can influence the capital
