Disinfecting a fluid with ultraviolet radiation

Abstract From the Canadian patent

A process of exposing a fluid medium, such as machine oil, to radiant energy and a device to carry out that process include providing at least two juxtaposed elongated radiant energy source, such as ultraviolet germicidal radiation sources, providing a passage between the sources that is typically less than an inch thick and that has walls capable of transmitting the radiant energy, providing for fluid flow in a direction substantially parallel to the radiant energy sources. passing a fluid medium in a thin film through the passage, and simultaneously exposing the fluid medium to the radiant energy by irradiating the fluid medium with the radiant energy sources. Preferably the passage is, …
