COST OPTIMIZATION OF DESALINATION SYSTEM AT NORTHERN COASTAL ZONE OF EGYPT

The coastal zone along Egypt represents a great opportunity for economy, agriculture and industrial activities, this coastal zone suffers from many threats such as sea water intrusion, shore line erosion and sea level rise, these threats will effect on the available water quality especially in agriculture, so, this study was achieved in order to investigate the possibility of using desalination system (Reverse osmosis) for saline ground water in new reclaimed area with affordable price. Through this study we were able to find out that there is many parameters will effect on the permeate water (desalinated water) such as water temperature, feed water TDS, applied pressure and the energy consumption in form of graphs, in this study we were able to define the performance of such system in such environment by using a graph that represents the distillated cubic meter price versus reclaimed are, we also determined the desalinated water cubic meter price for saline ground water of the Egyptian northern coastal zone, the cubic meter price range is from 4 LE t0 14.67 LE (from $0 to $0.92 per m3). at the end a group of recommendations were deduced.
