WIPO Patent Application WO/2022/239947

A1

The present invention relates to an indoor air purification system using microalgae. More specifically, the present invention relates to an indoor air purification system using novel microalgae, the system utilizing the abilities to remove, from fine dust of the microalgae, water-soluble contaminants such as nitrogen oxides, sulfur oxides and ammonium, and carbon dioxide, and release oxygen. The indoor air purification system using microalgae, according to the present invention, circulates indoor air through the present system by continuous aeration and, if the indoor air passes through the system, microalgae can reduce hazardous substances such as ultrafine dust, fine dust, VOCs and CO2 in the air, and produces refreshing indoor air through the generation of oxygen, which is beneficial to the human body, and maintenance of humidity. In addition, the indoor air purification system using microalgae, according to the present invention, can change the color of indoor lighting according to the type of microalgae to be used, and thus can be applied to various interior lighting and the like.
