Figure 7. Simulation investigation of the effect of agitation speed 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, operating pressure: 1 bar, and feeding mode: water feeding.
