Journal ArticleDOI
Synthesis of robust and high-performance aquaporin-based biomimetic membranes by interfacial polymerization-membrane preparation and RO performance characterization
Yang Zhao,Changquan Qiu,Xuesong Li,Ardcharaporn Vararattanavech,Wenming Shen,Jaume Torres,Claus Hélix-Nielsen,Rong Wang,Xiao Hu,Anthony G. Fane,Chuyang Y. Tang +10 more
TL;DR: A thin film composite ABM was prepared by the interfacial polymerization method, where AquaporinZ-containing proteoliposomes were added to the m-phenylene-diamine aqueous solution and achieved significantly higher water permeability and comparable NaCl rejection than controls.
Journal ArticleDOI
Desalination by biomimetic aquaporin membranes: Review of status and prospects
TL;DR: An overview of the properties of aquaporins, their preparation and characterization and the challenges in exploiting the remarkable properties are discussed, and various attempts to construct aquaporin in membranes for desalination are presented.
Journal ArticleDOI
Computational fluid dynamics simulations of flow and concentration polarization in forward osmosis membrane systems
Mathias F. Gruber,C.J. Johnson,Chuyang Y. Tang,Mogens H. Jensen,Lars Yde,Claus Hélix-Nielsen +5 more
TL;DR: In this paper, a computational fluid dynamics (CFD) model capable of simulating forward osmosis systems with asymmetric membranes is presented, which is inspired by previously published CFD models for pressure-driven systems and the general analytical theory for flux modeling in asymmetric membrane.
Journal ArticleDOI
Biomimetic aquaporin membranes coming of age
Chuyang Y. Tang,Zhining Wang,Irena Petrinić,Anthony G. Fane,Claus Hélix-Nielsen,Claus Hélix-Nielsen +5 more
TL;DR: The essentials of aquaporin protein function are summarized, the latest progress in this fascinating area of membrane research and development is reviewed and two main approaches have been suggested based on planar membranes and vesicles respectively.
Journal ArticleDOI
A feasibility study of ultrafiltration/reverse osmosis (UF/RO)-based wastewater treatment and reuse in the metal finishing industry
TL;DR: In this article, the technical and economic feasibility of adding an ultra-filtration process as a pre-treatment for removing dissolved and colloidal contaminants > 0.4μm, and to eliminate membrane fouling before a final reverse osmosis process resulting in permeate that would meet reuse criteria.
