| dc.description.abstract | The University of South-Eastern Norway has the plan to integrate a Centre for autonomous Particle Separation, Concentration and Refining (PASECOR) inside the new USN Innovation centre. Through research and innovation, PASECOR will deliver both a research based and sustainable technologies for purifying raw components from complex mixtures and solutions. The main goal of the proposed project was to further develop the PASECOR technology to make it ideal for separation and concentration of bacteria (1.0-0.2 micrometer) and microalgae (2.0-10.0 micrometer) from ocean water, lake water and raw oil solutions. From old versions of the PASECOR technology prototypes new fabrication methods and improved prototypes were designed and developed. These improved prototype include structures in order to improve the continuous separation, concentration and sorting efficiency, improve the flow through rate, improve the possibility to treat down to 5 micrometre particles and reduce the pressure drop to a minimum.
The new design consists of three chips including a top and bottom layer in borofloat33 glass and middle layer in silicon. The structured glass wafer was designed and evaluated in this project before fabrication in Germany. The silicon wafer is fabricated in IMS (Institute of microsystem) clean room by using micro and nano fabrication method, during this project. These three chips were supposed to be packaged together but the stack of three wafers with structure offered some potential challenges and work is still under progress | |
