Microfiltration is used to concentrate a suspension of latex particles from 2.5 wt percent to 20 percent.

Question:

Microfiltration is used to concentrate a suspension of latex particles from 2.5 wt percent to 20 percent. The particles are spheres with an average diameter of 0.2 μm. The membrane has a pure water permeability of 500 L/m²-h-atm. The permeate flux for c = 2.5 percent is 300 L/m²·h at Δp=30 lb_ƒ/in.² or 40 lb_ƒ/in.²

(a) Sketch a plot of flux versus Δp for c= 2.5 percent and compare with the typical plots for UF of medium size molecules.

(b) Estimate the maximum flux for c = 10 percent and c = 20 percent.
