A membrane is fouled with a layer of bacteria (a bioflim). Thewater permeability of the biofilm is 2 x 10-12 mol ms-1 m-2 atm-1 and is 21 μm thick.The membrane is 52 μm thick with a water permeability of 1 x10-12 mol m s-1 m-2atm-1. Neglect the convective mass transfer resistanceas they are very small.
The partial pressure of water of one side is 200 kPa and 101 kPaon the other.
Calculate the total mass flux of water through the combinedmembrane and biofilm in mol m-2 s-1 (3 SF) eg1.67E-8.
