Qualification of a corona type aerosol neutralizer

The air filtration process presents several advantages, helping to prevent damage to the environment and health of living beings, and to avoid damage to industrial processes equipment. The reliability of data obtained experimentally is very important in the industrial and scientific fields in any work area and is no different in air filtration. The objective of this work is to show the importance of the qualification of an important part of air filtration test rig. This qualification it is made to ensure greater representativity of the data. The equipment in question is a Corona type aerosol neutralizer. The qualification consists in tests to find out the better functioning and effectiveness of this type of neutralizer. The tests were performed at the Energy Department of the Politecnico di Torino in Italy. As a result of the qualification, the effort made to ensure that the aerosol neutralizer works properly is very beneficial. Since the operation of this equipment can greatly influence the reading of the sampled particles and, consequently, the filtration efficiency results obtained.
