Experimental investigations have been carried out to obtain pure water from saline water of high salt content.  The water is processed through a quartz sand filter, two  5 micron filters and then through an Reverse Osmosis(RO) unit.  The RO unit contains four   Dow SW30 – 4040 membranes.  The effects of applied pressure, feed  concentration are determined on outlet pressure, product stream flow rate and product concentration.  A useful correlation has been obtained that relates product water concentration as a function of feed water concentration and applied pressure.
