Question

In which of the following the large aerosol particles are deposited on the walls of airway conduit?

(a) Inertial Impaction

(b) Diffusion

(c) Electrostatic attraction

(d) Interception

I had been asked this question in an international level competition.

The doubt is from Filter Sterilization topic in section Sterilization of Fermentation Technology

Answer 1

The correct option is (a) Inertial Impaction

The best I can explain: The large aerosol particles are deposited on the walls of airway conduit in inertial impaction. The impaction occurs where the airway changes. It is more significant in the filtration of gases than in the filtration of liquids.
