Legionella: Bioactive nano-filters for air purification systems

Abstract

Legionnaires disease or legionellosis arose due to human alteration of the environment, Legionella species can be found in aquatic environments, water warm and hot, and humid places, such as cooling towers, spas, among others. This is an infectious disease caused by bacteria belonging to the genus Legionella. To reduce the multiplication of Legionella pneumophila and the associated risk of Legionnaires' disease should be taken measures to prevent and control physical, chemical and microbiological, in order to promote and maintain clean surfaces of water systems and air. One of the systems used for purification of air filtration consists in the separation and capture of particles of any kind. The filters need technical requirements that are a balance between three key parameters: the filter efficiency, pressure drop and the durability of the filter.
