Estimating the term…
A nanofiltration device for inactivating droplet-transmitted pathogens. The microdroplets are captured by filtering contaminated air on a filter material/paper with the nanofibrillated cellulose and/or nanocellulose surface treatment containing antiseptic metal ions and an adjuvant in the retained residual water. The air is sucked into the openings of the nanofiltration device located at the bottom and passes into the centre of the filter cartridge, in which a germicidal emitter emits radiation in the UV-C range of the electromagnetic wavelength spectrum is mounted. Subsequently, it flows through a filter paper containing salts of antiseptic metals, from the centre of the radiator outwards through a filter paper hermetically inserted into the filter cartridge, folded harmoniously-shaped so that its surface is maximally and entirely irradiated with UV-C radiation. Antiseptic ions diffuse into the contaminated microdroplets which with UV-C radiation deactivate viruses and disinfect bacteria. Subsequently, the droplets dry out, and the deactivated viruses and bacteria are carried away by air, which, with the help of adjuvants, receive the human body and increase the population's immunity.
A nanofiltration device of cylindrical or prismatic shape for inactivation of air-filtered pathogens through a filter containing inorganic additives in residual water on a cellulosic carrier with a flat base connected to the environment via a perforated base/pedestal with an interior space bounded by long-term stable material against the action of radiation in the UV-C range of the electromagnetic wavelength spectrum, placed longitudinally in the interior space of this device into the shape of a cylinder, longitudinally located in the interior space of this device into the shape of a cylinder, in which middle is longitudinally (axially) a germicidal emitter in the form of a cylinder or a U tube, emitting UV-C radiation, placed parallel to the direction of the incoming airflow into the interior of the filter cartridge hermetically insulated in the lower part of the interior space so that the air sucked in from the environment through the openings in the lower part of the device reaches only the centre of the cartridge, which is hermetically sealed from the top, so the airflow is directed through accordion-shaped arranged porous walls of filter paper sheet, wherein it contains nanofibrillated cellulose from corn-based distillery refuse and/or nanocellulose, adjuvants—aluminum compounds AlPO4, Al(OH)3, (Al)2PO4SO4OH and chitosan added below their solubility limit and nitrate salts Cu(NO3)2, Zn(NO3)2, Ca(NO3)2 and Mg(NO3)2 or other soluble salts of Cu, Zn, Ca and Mg in concentration below their solubility limit and the filter paper sheet is folded accordion-shaped in the filter cartridge so that its surface is maximal and completely irradiated with UV-C radiation and fan/fans is/are installed below and/or above the filter cartridge to provide a forced flow of air through the pores of the accordion-shaped folded filter sheet.
