A membrane filtration unit is operating with 85.2 m2 of membrane and processes 132 L/min feed of wastewater. The permeate flow is 84.8 L/min. The filter removes suspended solids from a waste stream such that the concentration in the permeate is 49.7 mg/L compared to 3,639 mg/L in the retentate. Determine the % water recovery (i.e., % volume reduction). Report answer to one decimal place.
