METHOD FOR REMOVING PARTICULATE MATTER IN INDOOR ENVIRONMENTS

摘要

Method for removing all types of particulate matter with exclusion of biological multiplying microorganisms in indoor environments characterized by comprising the following two steps:—the atomization of compounds that oxidize particulate matter to form complexes and to precipitate them;—the atomization of a liquid containing a mixture of spores of Gram-positive aerobic and/or of facultative anaerobic spore formers to act as nuclei for extra precipitation, to cover the precipitated particulate matter; and to metabolize precipitated particles and to take up precipitated particles by the Gram-positive bacteria/thereby preventing the precipitated particles to become airborne again;—whereby the drop size in both atomization steps is held between 5 and 50 μm to yield a dry nebula.
