Air Quality Control & Aerosols

Dr.-Ing. Stefan Haep, Institute for Energy and Environmental Technology e.V. (IUTA), Germany

The control of gaseous and particulate emissions and immissions caused by industrial processes result in filter solutions typically qualified by standardized test methods. The control of non steady loads, typical for real life operating conditions, requires the redesign of filters and the development of advanced testing procedures, especially for multi effect filter systems. Furthermore, this has to be accompanied by adaption and hyphenation of (cheap but robust) online measurement devices, gas and particle sensors and detectors. The latter is particularly of utmost importance for digitalization in filtration technology.

The presentation will cover these aspects, special emphasis is laid on the following topics:
• Potential of new CFD-tools to develop effective fibre structures for the filter design.
• Effect of particle charging to boost the separation efficiency of electret and non electret filter media.
• Methods to qualify multi effect filters under peak load conditions.

Another topic is bioaerosol measurement in the off-gas of cooling towers as a currrent challenge in air quality control...
