In October, master students in Sustainable Chemistry and some of our PhD students went to Trosa for a study visit to Camfil. Camfil manufactures systems for air purification and dust separation, and is a potentaial employer for students after graduation.

During the visit students learned about the air quality control in Stockholm, and took part in a demonstration from SEM imaging of hydrocarbons and other particulates in the air.  This was followed by a demo on how effectively air filters can remove such particulates.

Students also leaned about various air filters and their application in all from gas turbines to semiconducting industry and air filters in hospitals, home use and etc.

Interestingly, the materials that students prepare during the lab part of this course (activated carbons) is used highly in their filters for molecular adsorption.

The students, may return to Camifil with large amount of activated carbons to test the material in future.
