A reverse osmosis membrane water-treatment plant is designed to treat brackish water and to produce 2.0 MGD of permeate. The feed water has a salt concentration of 5,000 mg/L. The production recovery is expectod to be 82%. The permeate water must contain no more than 500 mg/L of salt. a) Draw and label a process flow diagram for the described process. ) How much water should be pumped to the membrane in MGD? 5) What is the flow rate (MGD) and salt concentration (mg/L) of the concentrate stream?
