RO recovery
Calculate the water recovery ratio from feed and permeate flows.
Equation and assumptions
Recovery = 100 Qpermeate/Qfeed; Qconcentrate = Qfeed − Qpermeate
Steady volumetric balance with no other flow outlets or recycles. Does not predict membrane rejection, scaling, pressure requirements, quality or allowable recovery.
