Abstract
The recent advancement in mechanically and chemically robust membranes has led to the capabilities of both reverse osmosis (RO) and pervaporation (PV) for separation of water/organic solvent and organic solvent mixtures. However, their performances are evaluated in different permeation formulas. To address this, we have conducted an analysis using a unified parameter: activity-based permeance. The present study evaluated RO and PV using the same organosilica membrane for the separation of both non-aqueous solvents (methanol/ethanol, methanol/iso-propanol [IPA], and methanol/dimethyl carbonate) and organic solvent-aqueous mixtures (including water with methanol, ethanol, IPA, tert-butanol, and glucose), at concentrations ranging from 0% to 100%. With the use of activity-based permeance, we achieved a consistent evaluation of both PV and RO processes. Moreover, this approach provides prediction of separation performance even in RO and PV.
