چکیده
|
Collapsing of the membrane is an undesirable phenomenon about ultrafiltration membranes prepared by phase inversion methods# since this phenomenon takes place during drying process, a post-treatment stage was used before drying process# in this study, 2-propanol and glycerol were used as alcohol in post-treatment stage for prevention of membrane collapsing# the results of pure water permeability tests showed that the flux of membranes which was prepared by post-treatment was close to the polyethersulfone ( pes ) membrane flux in wet state# also porosity and mean pore radius analysis were demonstrate that the post-treatment had positive effects on prevention of membrane collapsing#
