Abstract
This invention relates to a device including a combination of a porous filter and ultraviolet light source, that is for purifying fluid media. The porous filter filtering out particles suspended in the fluid medium and the ultraviolet germicidal lamp killing germs in the fluid medium are arranged in a combination in such a way that the porous filter distributes the fluid flow in a pattern that exposes the fluid medium to the germicidal radiation uniformly and thoroughly, while the ultraviolet germidical light destroys the bacteria and other germs contaminating the fluid medium, and at the same time cleans the porous filter continuously by oxidizing the organic particles clogging the porous filter wherein the oxidizing process utilizes oxygen naturally dissolved in the fluid medium or that artificially injected into the fluid medium.
