Ultraviolet wastewater disinfection system and method
DCFirst Claim
1. An ultraviolet disinfection (UV) system for treating waste-containing fluid, the system comprising at least one light source positioned within a housing and connected to a power source for producing a UV light output from the housing, the system including at least one optical component positioned between the at least one light source and the UV light output from the housing, thereby producing a focused, controllable UV light output that has at least one UV dose zone for providing effective sterilization of microorganisms within the fluid.

Abstract
An ultraviolet (UV) disinfection system and method for treating for treating waste-containing fluids including a configuration and design to function effectively with at least one UV light source or lamp that is not submerged in the fluid. The UV light source is positioned outside the fluid to be disinfected via exposure to at least one UV dose zone outside the fluid being treated wherein UV light is projected into the at least one dose zone. The UV light source may be presented in a vertical riser configuration, wherein the UV light source is positioned above the fluid to be treated and projecting a UV dose zone downward toward and into the fluid to be treated, with the fluid moving upward toward the UV light source. At least one interface plate is used to provide a surface zone for UV disinfection above the fluid and to provide additional treatment means for balancing pH, affecting effluent chemistry, reducing organic chemicals, and the like. Alternatively, the UV light source may be presented in a planar or horizontal design, wherein the UV light source is positioned above the fluid to be treated and projecting a UV dose zone downward toward and into the fluid to be treated, with the fluid moving in a direction substantially perpendicular to the UV dose zone. Thirdly, the UV light source may be presented in a reservoir configuration, wherein the UV light source is positioned above the fluid to be treated that is contained in a reservoir.

65. A method for providing ultraviolet disinfection (UV) of waste-containing fluids, the method comprising the steps of
providing a UV disinfection system comprising at least one UV light source coupled with at least one UV-transmissive optical component outside a fluid to be treated and at least one interface zone positioned between the at least one UV light source and the fluid to be treated, the at least one UV light source designed, configured, and connected to produce UV light creating at least one UV dose zone outside the fluid; -
presenting a surface zone on the at least one interface zone, wherein the surface zone has a UV dose zone associated therewith for disinfecting the fluid to be treated;
introducing a pre-treated fluid into the system, the fluid passing through at least one UV dose zone within the fluid and passing through the at least one interface zone and surface zone UV dose zone;
disinfecting the fluid via exposure to the UV light in the UV dose zones;
dispensing the disinfected fluid outside the system. - View Dependent Claims (66, 67, 68, 69)
