Seawater containing water and NaCl only with an NaCl concentration of ## kg/m3 (where ## are the last two digits on the right of your KU ID number, e.g. 100012345 then ## will be 45) enters a reverse osmosis membrane module at a flow rate of 290 m3/d. The desired pressure, total flowrate and concentration of NaCl in the permeate are 101.3247 kPa, 150 m3/d and 0.3 kg/m3, respectively. The values of the permeability coefficients for water and NaCl of the membrane are 3x10-6 m3/m2.s.kPa and 3x10-7 m3/m2s, respectively. The membrane module is designed such that the brine pressure is 90% of the feed pressure. Calculate the recovery, feed and brine pressures, total membrane area, NaCl flowrate through the membrane, brine flowrate and NaCl concentration, NaCl rejection and passage.
