<p>An ultraviolet (UV) disinfection system and method for treating fluids including a configuration and design to function effectively with at least one UV light source or lamp (56) that is not submerged in the fluid. The UV light source (56) is positioned outside the fluid to be disinfected via exposure to at least one UV dose zone (57, 53, 52) outside the fluid being treated wherein UV light (55) is projected into the at least one dose zone (57, 53, 52). The UV light source (56) may be presented in a vertical riser configuration, wherein the UV light source (56) is positioned above the fluid to be treated and projecting a UV dose zone (57, 53, 52) downward toward and into the fluid to be treated, with the fluid moving upward toward the UV light source (56). Alternatively, the UV light source (56) may be presented in a planar or horizontal design, wherein the UV light source (56) is positioned above the fluid to be treated and projecting a UV dose zone (57, 53, 52) downward toward and into the fluid to be treated, with the fluid moving in a direction substantially perpendicular to the UV dose zone (57, 53, 52). At least one interface plate (59) is used to provide a surface zone (53) for UV disinfection above the fluid and to provide additional treatment means for balancing pH, affecting effluent chemistry, and the like.</p> |
