AiF-Project "sensoric process monitoring of reverse osmosis systems" (21335 N)
The use of intelligent inline analysis and data processing methods enable to link information in order to accommodate options and guidance to ensure...
A research focus of the Institute of Particle Process Engineering is the development of new measurement methods for particle concentration, size (mean- and distribution) and velocity, using the Statistical Extinction Method (SE-Method). A main research aspect is the inline implementation of the measurement method in industrial relevant applications. To successfully accomplish new sensors for specific particle systems, the experimental and simulative experience of more than 10 years is gathered. It was conducted under the direction of Prof. Ripperger and will continue under his successor, Prof. Antonyuk.
The research verified the SE-Method as suitable for particle system from 1 µm to about 3 mm and up to 30 vol% concentration to deliver reliable and reproduceable measurements in sprays, emulsions and suspensions.
The future research will be focused on the application of the SE-Method for particle sizes starting at 1 nm.
