Dear all members, Hydrophobis membrane usually must be prewetted. And in every book or journal I have read, they always use ethanol. I am confuse. Why must ethanol? Why not methanol instead? Thank you, Yul

I measure liquid (water) separation The operating conditions : pressure = 2atm. The ethanol exposure as a pretreatment is an exposure on a fabricated membrane in hopes of modifying its performance, to improve the water fluxes with no loss in rejection. Thank you very much.

I am doing a research with polysulphone membranes. The pretreatment for the membranes was done by submerged it in the ethanol 80%. As far as I know, after submerged in the ethanol, the flux should be going up. But my experiment result showed that the flux was going down. Can anybody please help...
