In this work, a practical separation performance was investigated on aqueous alcohol solutions,
especially for iso-propyl alcohol (IPA), which is usually used during the semi- conductor rinsing process. The
removal of various substances from waste aqueous IPA solutions was carried out by microfiltration with 0.11
pore size of mean diameter as a pre-filter.
Permeability and molecular weight cut-off of the functional polysulfone(PSf) ultrafiltration membrane to purify
waste aqueous IPA solutions were measured through the ultrafiltration test. The solute rejection of PSf membrane
had 92% in 1,000ppm aqueous PEG solution with PEG molecular weight 10,000, the molecular weight cut-off
had 10,000.
The IPA concentration on the CMPA-K+ membrane performance using pervaporation module system could be
increased from 95.04 wt% to more than 98.50wt% in about 9hr at operation temperature of 70 using the
pervaporation module system. |
