A large-scale RO membrane system has a feed water flow rate of 100 mgd , and a retentate
flow rate of 45 mgd . The total dissolved solid (TDS) level in the feed water is 10,000mg//L,
and the permeate stream has a TDS level of 10mg//L.
(a) Calculate the recovery rate of this RO system.
(b) Calculate the rejection rate of this RO system.
