effect of teg additive on the morphology and performance of pes ultrafiltration membrane

Ultrafiltration (uf) membranes are commonly used for treatment of oily wastewater that could be harmful to the environment and human health# these two issues are discussed in the current study to investigate the additive and coagulation bath temperature (cbt) effects on the membrane performance and morphology# first, the effect of teg concentrations in the casting solutions has been investigated to obtain a membrane with the desired pore size# second, the influence of cbt on the membrane morphology has also been assessed# the results showed that increasing the teg content in the casting solution has diversely affected the membrane performance, and increasing cbt from 25°c to 45°c leads to the formation of the membrane with a larger mean pore size#
