Figure 8. Simulation investigation of the effect of operating
pressure on (a) permeate flux, (b) solute flux, and (c) permeate
concentration 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 feeding mode: water feeding.
