Question

Problem 2. A reverse osmosis membrane has a kw values of 2.5-10 L/(m²-s-bar) and an
average ks value of 3.5.10+ L/(m²-s). Find the expected permeate salt concentration of
chloride if the feed concentration is 4500 mg/L, the system operates at a gauge pressure
of 35 bar on the feed side of the membrane, and 95%. Assume the permeate has a
negligible osmotic pressure. Answer: 171 mg/L.

A ground water with salinity (TDS) of 2850 mg/L is treated with reverse osmosis desalination process for drinking water production and the permeate salinity (TDS) is measured to be 200 mg/L. The feed flow rate and permeate flow rate of the membrane process are 4000m³/d and 3200m³/d, respectively. It is known the resistance of the membrane Rm is 10¹¹ Pa-s/m and the driving pressure AP is 10 bar. The osmotic pressure of the water can be determined by the rule of thumb (psi) = 0.01 TDS (mg/L). Determine (1) the required salt rejection rate of the membrane, (2) the recovery of the RO process, (3) the permeate flux through the membrane and the required membrane area, (4) the flow rate and salinity (TDS) of the concentrate flow.
