Question: A membrane filtration unit is operating with 75.3 m 2 of membrane and processes 143 L/min feed of wastewater. The permeate flow is 86.1 L/min.

A membrane filtration unit is operating with 75.3 m² of membrane and processes 143 L/min feed of wastewater.

The permeate flow is 86.1 L/min.

The filter removes suspended solids from a waste stream such that the concentration in the permeate is 15.8 mg/L compared to 3,741 mg/L in the retentate.

Determine the flux of permeate (in L/m²/d). Report answer as a whole number (no decimal).
