Reverse osmosis process is used for drinking water production using seawater and brackish water.A small seawater reverse osmosis (SWRO) plant with 200 m membrane area is presented in the following figure, detailed operational parameters are presented in the table. Reverse Osmosis Feed water Qin Qout Product Cin Cout water Q Concentrate C Flow rate Qin (L/Day) Salt concentration Cin Flow rate Qout 4x106 (mg/L) 36000 (L/Day) 1.6x106 Salt concentration Cout (mg/L) 430 AC = Cin-Cout JwA(APA), Js = BAC (a) Calculate the permeate flux (L/(m Hour) and water recovery (b) Assume that osmotic pressure of the seawater is 27 bar and the applied pressure for RO system is 55 bar, calculate the water permeability coefficient A. (c) Calculate the salt rejection of the RO system.
