About the Open Membrane Database
What is the OMD?
The Open Membrane Database (OMD) is an open-access, crowd-sourced resource with the performance and properties of 662 reverse osmosis (RO) membranes. The interactive charts and search functions allow easy data exploration and comparison of membrane performance, physicochemical properties and synthesis conditions.
Researchers are encouraged to upload their latest membrane performance results (see Submit a Membrane) to update the OMD with state-of-the-art membrane technologies. Only data published in peer-reviewed journals, patents, or commercial product datasheets is allowed on the database to provide quality control.
Currently, the OMD only contains RO membranes. The goal is to later incorporate other membrane-based separations technologies such as nanofiltration (NF), forward osmosis (FO), and ion-exchange (IX) to name a few. Please get in contact with us if you would like to contribute to this exciting collaborative effort of sharing and compiling membrane data, or if you have questions or comments!

People behind the OMD
Dr. Rhea Verbeke is co-founder of the OMD. She obtained her PhD at KU Leuven in 2020 and conducted research at Yale University, the R&D Department of DuPont Water Solutions and the Research Neutron Source of the TU Munich. She has pioneered the use of epoxide chemistry for TFC membrane synthesis, and explored advanced physico-chemical characterization methods, including ERD and PALS. Her work targets the development of chemically robust water purification membranes for applications in harsh conditions.
Dr. Timothée Stassin is co-founder of the OMD. He obtained his PhD at KU Leuven on the vapor-phase processing of metal-organic framework powders and thin films. His current interests as an independent researcher include bridging the gap between high-tech academic research and low-tech field solutions, and the development of collaborative and multidisciplinary research platforms.
Ines Nulens obtained a M.S. degree in Bio-Science Engineering (Environmental Technology) from KU Leuven in 2017. In 2018, she joined the Membrane Technology Group to pursue a PhD on the topic of TFC membrane development using ionic liquids and the synthesis-morphology-performance relationship of polyamide TFC membranes.
Dr. Douglas Davenport earned his PhD in Chemical Engineering from Yale University in 2020 where he studied high-pressure reverse osmosis (HPRO) for hypersaline brine desalination. His PhD combined industrial and theoretical perspectives as he constructed a crossflow apparatus capable of operating at 150 bar in order to study the fundamentals of thin film composite membrane compaction in HPRO. Douglas is continuing his work as a postdoctoral researcher at KU Leuven where he is working to synthesize novel membrane chemistries at pilot scale.
Dr. Zhe Yang a post-doc fellow of Environmental Engineering and received his PhD degree from the University of Hong Kong in 2018. In July of 2016, he was a visiting PhD student in SCELSE (Singapore Centre for Environmental Life Sciences Engineering) Summer Course in Nanyang Technological University. His research interests focus on membrane separation, desalination and water reuse. He was a Guest Editor of Membranes for a special issue on “Membranes for Environmental Application 2020”. He is also an inventor of 2 patents, and the invention of a rapid water filter received a Gold Medal at the 2019 Geneva International Exhibition of Inventions.
Adi Ben Zvi is a PhD student in Professor Guy Ramon's group at the Technion - Israel Institute of Technology, studying synthesis-morphology-performance relations in polyamide membranes, via the IP reaction. Her research is inspired by halophytic plants: understanding their mechanism of salt separation, and utilizing their biomaterials and morphology to synthesize biomimetic membranes.
Naama Segev PhD student at the Technion - Israel Institute of Technology in the Faculty of Environmental Engineering under the supervision of Associate Professor Guy Ramon. Her research interests include membrane fouling visualization, oily wastewater membrane based separation, membrane surface interactions and fouling mitigation.
Cody Ritt is a PhD candidate in the Elimelech Research Group, part of the Department of Chemical and Environmental Engineering at Yale University. He received his B.S. and M.S. in Civil Engineering from North Dakota State University (NDSU). His research at Yale has focused on applied nanofluidics, with topics ranging from Monte Carlo simulations of desalination across 2D nanomaterial membranes to experimentally elucidating the mechanisms which govern polyamide ionization.
Ryan DuChanois is a Ph.D. Candidate in the Department of Chemical and Environmental Engineering at Yale University under the supervision of Professor Menachem (Meny) Elimelech. Ryan received a B.S. in Civil Engineering from the University of Arkansas and was the top graduate in the College of Engineering. Ryan also was a Gates Cambridge Scholar at the University of Cambridge, where he completed an MPhil in Engineering for Sustainable Development and received the Water Conservators Best Dissertation Prize. Now at Yale, Ryan seeks to improve the molecular selectivity of synthetic desalination and ion-selective membranes using principles of biological channels. His Ph.D. focuses specifically on developing membranes that are able to selectively remove a single ionic species from water, such as a contaminant or valuable resource.
Prof. Ivo Vankelecom studied Bioscience Engineering at the Catholic University of Leuven (KU Leuven), Belgium, where he graduated in 1990. In 1994, he obtained his PhD in Applied Biological Sciences from the Department of Interphase Chemistry on "Inorganic Porous Fillers in Organic Polymer Membranes". He subsequently worked at KU Leuven as postdoc on membrane catalysis.
