Question details

A Reverse Osmosis (RO) system is used to produce potable water from saline water. The feed rate (influent) is QF=35.231 Gal/d, the permeate flow (effluent) is QP= ? Gal/d and the waste flow rate is QW= ? Gal/d. The salt concentration in QF is SF=38990.538 mg/L and the salt concentration in the permeate is SP=2.5 mg/L. What is the concentration of salt= ? mg/L in the waste stream? Given: QP=0.8*QF ; QW=0.2*QF
