Abstract

Fluid disinfection apparatus (10) comprising a reservoir (12) for holding fluid (20) to be disinfected, a cylindrical roller member (14) and an array of (12) ultra violet lamps (16). The roller member (14) is partly received within the reservoir (12) and is thus partly submerged in the fluid (20). As the roller member (14) rotates (as indicated by the arrows), fluid (20) is picked up by the surface of the roller member (14) from the reservoir (12). The fluid (20) is dispersed into a film of fluid (20) across the surface (34a). The ultra violet (UV) lamps (16) are mercury arc discharge lamps which output UV light (10) including germicidal wavelengths: 220nm to 280nm. Exposure of the fluid film to the UV light kills or inactivates any micro-organisms within the fluid (20).
