Preparation of acrylonitrile-butadiene-styrene membrane: Investigation of solvent/nonsolvent type and additive concentration

In the present study, preparation of acrylonitrile-butadiene-styrene (ABS) membrane was investigated via phase inversion method. ABS membrane is sensitive to preparation conditions. Therefore, the effect of solvent/nonsolvent type and concentration of additive and ABS was evaluated on the morphology, tensile strength and car wash wastewater treatment. Polyethylene glycol was used as an additive. The results show that nonsolvent type significantly affects the morphology and consequently the flux and rejections of the pollution indices. Increasing concentration of additive and ABS in the casting solution leads to formation of denser and thinner membranes that have lower flux and higher rejections of the pollution indices.
