At the higher salt concentration level, the analysis shows that TF-1000 handles salts MgCl2 (treatment 1) and Na2SO4 (treatment 2) in a comparable manner in terms of permeate flux (μ1 = μ2), but handles NaCl (treatment 3) in a significantly different manner than both MgCl2 and Na2SO4 (μ1 ≠ μ3; μ2 ≠ μ3).
