Development of Graphene Oxide Membranes for Pervaporative Desalination
(University of Waterloo, 2018-09-04)Fresh water scarcity is quickly becoming a serious global challenge as populations grow and resources are depleted. Seawater, which makes up 97% of the water on Earth, can be a viable and sustainable source of usable water ... -
Layer-by-layer Self-assembly Membranes for Solvent Dehydration by Pervaporation
(University of Waterloo, 2013-12-09)In this study, polyelectrolyte membranes were prepared by layer-by-layer self-assembly on top of an interfacially polymerized polyamide substrate, and these thin-film-composite membranes were studied for pervaporative ... -
Preparation, Characterization and Performance of Poly(vinyl alcohol) based Membranes for Pervaporation Dehydration of Alcohols
(University of Waterloo, 2008-09-24)Pervaporation (PV), a non-porous membrane separation process, is gaining considerable attention for solvent separation in a variety of industries ranging from chemical to food and pharmaceutical to petrochemicals. The most ... -
PVAm-PVA Composite Membranes Incorporated with Carbon Nanotubes and Molecular Amines for Gas Separation and Pervaporation
(University of Waterloo, 2014-01-02)This study deals with polyvinylamine (PVAm)-poly(vinyl alcohol) (PVA) based composite membranes incorporated with carbon nanotubes (CNTs) and molecular amines (e.g., piperazine (PZ), triethanolamine (TEA), N-methyldiethanolamine ... -
Recovery of Dairy Aroma Compounds and Concentration of Dairy Solutions by Membranes
(University of Waterloo, 2018-05-25)This study explores the potential of using different types of poly(ether block amide) (PEBA) membranes for recovering aroma compounds from dairy solutions and concentration of dairy products by membrane processes. The ... -
Synthesis and Modification of Polymer Membranes for Pervaporation and Gas Separation
(University of Waterloo, 2007-10-23)Trimesoyl chloride (TMC) crosslinked poly(vinyl alcohol) (PVA) / chitosan (CS) membranes and synthetic polyimide membranes were prepared for pervaporation dehydration of isopropanol and gas separation. PVA membranes were ... -
Thin Film Composite Membranes Derived from Interfacial Polymerization for Nanofiltration and Pervaporation Applications
(University of Waterloo, 2015-04-20)In this study, thin film composite (TFC) membranes were prepared by interfacial polymerization on a microporous polyethersulfone (PES) substrate. These membranes were studied for salt separation by nanofiltration and ...
