Figure 9. Simulation investigation of the effect of feeding
mode on (a) permeate flux, (b) solute flux, (c) permeate concentration,
and (d) yield and specific energy consumption with membrane pore size of
10 nm and membrane porosity of 0.8. Substrate concentration: 50 g/L,
enzyme concentration: 0.05 g/L, agitation speed: 1000 rpm, and operating
pressure: 3 bar.
