AB  - Cellulose acetate (CA) ultrafiltration membranes were successfully prepared using 
      the non-solvent induced phase separation (NIPS) methodology. This technique is 
      used to produce porous membranes for a large variety of applications. However, 
      the formation of a dense skin during the process reduces membrane pure water flux 
      (PWF). To overcome this issue, three parameters were investigated: CA/NMP 
      (N-methyl-2-pyrrolidone) ratio in the casting solution, acetone (Ac)/water (W) 
      ratio in the precipitation bath composition (PBC) and support material 
      (glass/polyethylene). The effect of each factor on the mean pore size, water 
      contact angle, porosity and PWF was supported by Taguchi design. The increase in 
      the CA/NMP ratio reduced mean pore size and porosity. In contrast, there was an 
      increase in porosity and hydrophilicity with increasing Ac/W ratio. The maximum 
      value of PWF was obtained for membranes prepared using a PE support. ANOVA showed 
      that most, but not all, factors had significant effects on the parameters 
      measured.
