In the current work, small-pore polyethersulfone (PES) UF membranes with narrow size distribution and high surface porosity were successfully prepared from PES casting solution with different size of nano-CaCO3 and coagulated in HCl solution. The different sizes of nano-CaCO3 particles (22-6 nm) were produced through modulating HCl/nano-CaCO3 molar ratios in the casting solution. The nano-CaCO3 size and produced CaCl2 could synergistically affect the viscosity of the casting solution and then regulated the structure and performance of the PES UF membranes.
