Reliable fresh water supplies from challenging water
The world's water consumption rate is doubling
every 20 years, outpacing by two times the rate of population growth. It is projected
that by the year 2025 water demand will exceed supply by 56%, due to persistent
regional droughts, shifting of the population to urban coastal cities, and water
needed for industrial growth. The supply of fresh water is on the decrease. Water demand for food, industry and people
is on the rise.
Lack of fresh water reduces economic
development and lowers living standards. Clearly, there is a critical worldwide need to better manage this
increasingly valuable resource.
Desalination systems from GE Water & Process
Technologies can make abundant fresh water both from seawater and from challenging
Oceans make up 97% of
the worlds supply of water. Desalination using seawater reverse osmosis
(SWRO) membrane technology has become a viable option for the development of new
regional water supplies.
GE Water & Process Technologies is the world leader in the supply of
reliable seawater SWRO
membrane desalination systems. GE's desalination projects range in size
from small 2,000 cubic meter/day (370 gpm) plants -- providing potable water
to hotels and resort complexes -- all the way up to projects like the 200,000
cubic meter/day (53 MGD) Hamma Desalination Plant, the largest of its kind
in Africa. Hamma supplies desperately-needed drinking water to over 20%
of the population of Algerias capital city.
over 20 years of seawater SWRO desalination operating and maintenance expertise,
GE leads the industry in its practical knowledge of SWRO membrane design, SWRO
membrane pretreatment design, SWRO membrane cleaning techniques, energy recovery
devices and the selection of material of construction.
Brackish water, containing minerals and salts typically less than 5,000 ppm
total dissolved solids (TDS), can be economically treated with today's reverse
osmosis (RO) and electrodialysis
reversal (EDR) systems. Effective mineral and salt removal converts previously
unusable waters to high-purity resources for drinking, irrigation or industrial
GE pioneered brackish water desalination in the early 1950s and continues
to lead the way with cost-effective,
environmentally friendly treatment systems for groundwater and surface
water sources. Our global installed capacity includes approximately 250 mgd
(950,000 m3/day) of EDR systems and 600 mgd (2.3 million m3/day) of RO systems.
EDR and RO
systems are available in fixed land-based and mobile designs. GE designs and builds
the systems and in many cases also operates them under full-service build-own
