Description

An odor is caused by one or more volatilized chemical compounds generally at a very low concentration. It is percieved by the sense of olfaction, and its effect are vary by individuals. That is why it is treated one of the most particular air pollution to solve. Odor is caused by a main generating source facility and damages by the source spreads around the area or even spreads wider by instable climatic condition.

UV photocatalyst air purification

The UV photocatalyst air purifier is based on photo catalytic oxidation, and an emerging air purifier technology that converts fine particles and toxic gasses into safer compounds. When UV light shines on the titanium dioxide, electrons are released at its surface. It's the electrons that do the useful work for us. The electrons interact with water molecules (H2O) in the air, breaking them up into hydroxyl radicals (OH−), which are highly reactive, short-lived, uncharged forms of hydroxide ions (OH−). These small, agile hydroxyl radicals then attack bigger organic pollutant molecules, breaking apart their chemical bonds and turning them into harmless substances such as carbon dioxide and water.
