biomimetic Aquaporin membranes coming of age
Desalination, 2015Co-Authors: Chuyang Y Tang, Zhining Wang, Claus Helixnielsen, A G Fane, Irena PetrinicAbstract:Abstract Membrane processes have been widely used for water purification because of their high stability, efficiency, low energy requirement and ease of operation. Traditional desalting membranes are mostly dense polymeric films with a “trade off” effect between permeability and selectivity. Biological membranes, on the other hand, can perform transport in some cases with exceptional flux and rejection properties. In particular the discovery of selective water channel proteins – Aquaporins – has prompted interest in using these proteins as building blocks for new types of membranes. The major challenge in developing an Aquaporin-based membrane technology stems from the fact that the Aquaporin protein spans a membrane only a few nanometers thick. Such ultrathin membranes will not be able to withstand any substantial pressures, nor being industrially scalable without supporting structures. Incorporating Aquaporin proteins into compatible materials, while ensuring membrane performance, scalability, and cost-effective production, is crucial for a successful technology development. Since the first suggestions for using Aquaporins in membrane technology appeared around ten years ago, two main approaches have been suggested based on planar membranes and vesicles respectively. Here we summarize the essentials of Aquaporin protein function and review the latest progress in this fascinating area of membrane research and development.

Development of a bio- mimetic membrane module for desalination of sea-water through forward osmosis ( FO ) Kolofon
Membranes, 2015Co-Authors: Angel C I D Amor, Anthony Gordon Fane, Claus Hélix-nielsen, Chuyang Y Tang, Zhining Wang, Irena Petrinić, Agata Zarebska, T Cath, Amy Childress, Menachem ElimelechAbstract:Aquaporins are water channel proteins with excellent water permeability and solute rejection, which makes them promising for preparing high-performance biomimetic membranes. Despite the growing interest in Aquaporin-based biomimetic membranes (ABMs), it is challenging to produce robust and defect-free ABMs that can be easily scaled up. In the current study, a thin film composite (TFC) ABM was prepared by the interfacial polymerization method, where AquaporinZ-containing proteoliposomes were added to the m-phenylene-diamine aqueous solution. Control membranes, either without Aquaporins or with inactive (mutant) Aquaporins, were also similarly prepared. The separation performance of these membranes was evaluated by cross-flow reverse osmosis (RO) tests. Compared to the controls, the active ABM achieved significantly higher water permeability (~4L/m 2hbar) with comparable NaCl rejection (~97%) at an applied pressure of 5bar. Its permeability was ~40% higher compared to a commercial brackish water RO membrane (BW30) and an order of magnitude higher compared to a seawater RO membrane (SW30HR), which clearly demonstrates the great potential of the TFC ABM for desalination applications. © 2012 Elsevier B.V..

desalination by biomimetic Aquaporin membranes review of status and prospects
Desalination, 2013Co-Authors: Chuyang Y Tang, Rong Wang, Claus Helixnielsen, Yijiang Zhao, A G FaneAbstract:Abstract Based on their unique combination of offering high water permeability and high solute rejection Aquaporin proteins have attracted considerable interest over the last years as functional building blocks of biomimetic membranes for water desalination and reuse. The purpose of this review is to provide an overview of the properties of Aquaporins, their preparation and characterization. We discuss the challenges in exploiting the remarkable properties of Aquaporin proteins for membrane separation processes and we present various attempts to construct Aquaporin in membranes for desalination; including an overview of our own recent developments in Aquaporin-based membranes. Finally we outline future prospects of Aquaporin based biomimetic membrane for desalination and water reuse.

Control membranes, either without Aquaporins or with inactive (mutant) Aquaporins, were also similarly prepared. The separation performance of these membranes was evaluated by cross-flow reverse osmosis (RO) tests. Compared to the controls, the active ABM achieved significantly higher water permeability (∼4 L/m 2 h bar) with comparable NaCl rejection (∼97%) at an applied pressure of 5 bar. Its permeability was ∼40% higher compared to a commercial brackish water RO membrane (BW30) and an order of magnitude higher compared to a seawater RO membrane (SW30HR), which clearly demonstrates the great potential of the TFC ABM for desalination applications.
