Twente has always been a pioneer in membrane technology. About 50 years ago, with the arrival of Kees Smolders, research on membranes started at the Technische Hogeschool Twente, later University of Twente. And some 10 years later, Ton Burggraaf and his group started developing ceramic membranes. The history book ’50 years of membrane research in … Continue reading 50 years of membrane research in Twente
This summer, Betase has launched two new websites with technical background stories. The website membranes.nl contains technical background stories on membranes and membrane technology in the Dutch and English language. In order to get a good overview of ‘the whole picture’, to raise awareness of this technology, to gain better understanding of their functioning, and … Continue reading Betase launches two new websites
The porosity of a material indicates what is the volume of empty space with respect to the total volume. So if you know that a material is 25% porous, then it consists for 75% of ‘real material’, and the remaining quarter is ‘nothing’ or air. But in addition to this absolute value for the porosity, … Continue reading Data processing of membrane characterisation by permporometry
After several years of development, researchers at the Universities of Twente and Amsterdam and the Energy research Centre of the Netherlands have succeeded in obtaining a membrane system which is hydrothermally stable under semi-industrial dehydrating conditions at elevated temperature. This organic-inorganic hybrid membrane system combines the best of both worlds: flexibility and water repelling properties … Continue reading Breakthrough in pervaporation membrane for dehydration of solvent streams
Betase invests in new technologies. This is illustrated by our participation in 2006 and 2007 in a project to demonstrate how small-scale (surface) water purification can be realised economically and technically using mobile, compact, robust ceramic membrane systems. In this project, partly funded by the Province of Fryslân, we cooperated with membrane manufacturer Hyflux CEPAration, … Continue reading Demonstration of innovative water purification system
This article presents the state of the art (2005) of ceramic membranes for gas separation, particularly for the separation of hydrogen from process streams. It includes an overview of recent literature and reveals the best types of membranes for hydrogen separation, with their strong and weak points as well as key players based on patent positions. … Continue reading Ceramic membranes for gas separation – Recent developments and state of the art
