Many communities need affordable inland desalination
to meet increasing water demands by making
brackish water sources available for use in supplementing
existing water supplies or to control the salinity of
current sources. Most desalination technologies generate
two streams, a desalinated product water stream
and the saline byproduct referred to as concentrate.
Management of the concentrate stream, typically
15-30% of the feed flow, presents the greatest challenge
to implementing desalination.
This research demonstrated the novel use of existing
technologies to reduce the cost and energy consumption
for desalination with zero liquid discharge (ZLD) of concentrate.
Test results indicated treatment of the concentrate
for further recovery by a second application of reverse
osmosis could lead to significant reductions in desalination
costs and energy consumption to achieve ZLD. The
approach described here could cut ZLD costs by 50-70%
and reduce energy consumption by 60-75% compared
with established methods currently in use. Includes 10 references, tables, figures.
