SEA WATER REVERSE OSMOSIS SYSTEMS (SWRO)
Nowadays rapid
increase in population and industrialization has negative impacts on the earth.
Despite the improving technology the sustainable devellopment is only possible
at very high devlopped countries. This is an important factor for the
destruction of the natural ressources.
One of the
actual impacts of this situation is the extinction of the water ressources due
to “Global Warming”. Only 5 % of the overall Water ressources are usable. On
the other hand the biggest wtaer ressources are sea waters. For this reason sea
water treatment and use as fresh water ressource has been develloped and began
to be used as a common method.
Considerable
decreases in investment and operational costs since 1950 when Reverse Osmosis
was first introduced is one of the motives for increase in numbers of Reverse
Osmosis projects.
Sea Water
Reverse Osmosis (SWRO) systems are used in order to eliminate high
concentrations of dissolved ions in the sea water and hence to decrease the
conductivity values of the water.
Previously the
high energy demand for the high pressure pumps was the main drawback for
Reverse Osmosis systems. However today’s technology allows us to use energy
recovery systems installed on the concentrate line of the systems which return
the mechanical energy to the system. These technologies provide upto 50 %
energy savings.
Common energy
recovery systems are the “turbo charger” tcehnology which is relatively older
and “pressure exchanger” technology where energy transfer is done through the
pressure exchange.
Pressure
Exchange technology which is a relatively newer technology provides higher
energy savings withrespect to turbo charger systems.
Approximately
36.000 ppm salt concentration in sea Water may decrease at the output stage
with approximate values:
TDS: 250-300
ppm (tap water levels)
Chlorine: 150
ppm olacaktır.
For lower
conductivity and chlorine demands a secondary RO unit should be added at
the SWRO output line.
