Hybrid organic-inorganic pervaporation membranes for desalination
Membrane desalination using reverse osmosis (RO) has been the leading candidate technology for supplying fresh water in recent years. However, there is a strong motivation for improving the established membrane process and/or developing alternative membrane technologies to overcome the limitations …

Factors required to enhance water recycling at two major Australian industrial manufacturing sites
This study presents the application of an integrated water management strategy at two large Australian manufacturing companies that are contrasting in terms of their respective products and wastewater generation. The integrated strategy, consisting of water audit, pinch analysis and membrane …

The selective separation and extraction of metals using membrane technology
… has been difficult because of the very similar chemical properties of these transition metals that are situated alongside each other in the Periodic Table. The work contained in this thesis shows the membrane extraction of the metals: Cobalt(II), Nickel(II). Iron(II) and Iron(III) in aqueous …

Theoretical and experimental investigation of membrane distillation
Invented in the 1960s, membrane distillation is an emerging technology for water treatment attracting more attention since 1980s. There are four configurations of membrane distillations including air gap membrane distillation (AGMD), direct contact membrane distillation (DCMD), sweep gas membrane …

Improving the durability and performance of hollow fibre membranes with nanocomposite and inorganic/organic hybrid materials
Water is a vital element for our existence but secure supply is challenged by population pressures and climate change. To ensure water security, it is essential to explore new sources and to recycle water for non-potable applications to reduce demand for the more valuable potable water. Membranes …

Carbon-nanotube-based membranes for water desalination by membrane distillation
This work investigates ways to fabricate composite macro-structures made of carbon nanotubes in combination with polymers and metals to enhance membrane lifespan and performance. Carbon nanotube Buckypapers were used as a template to engineer composite structures. The new materials have been …

The use of dense carbon dioxide extraction and fractionation to recover and refine natural food ingredients from food processing wastes
This study investigated the use of dense carbon dioxide, in both liquid and supercritical states, to extract and fractionate food by-product oils dispersed in porous matrices. Two oils were studied - Rice bran oil and Orange oil
