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!

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.

Founding members

Ines Nulens, founding member of the Open Membrane Database
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, founding team member of the Open Membrane Database
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, founding member of the Open Membrane Database
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, founding member of the Open Membrane Database
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.
