Patent ID: 7097764

Claim:
An apparatus for irradiating fluids with UV comprising: a reactor vessel having a fluid inlet, a fluid outlet and a reaction chamber; a plurality of UV lamps extending horizontally across the reaction chamber and substantially perpendicular to a horizontal axis extending between the fluid inlet and the fluid outlet, wherein said plurality of UV lamps are arranged in a substantially circular array such that at least two of said lamps are located above said horizontal axis and at least two of said lamps are located below said horizontal axis, and wherein two of said lamps located closest to said fluid inlet are upstream lamps and remaining ones of said lamps are downstream lamps; an upper fluid diverter positioned above said lamps and a lower fluid diverter positioned below said lamps, said upper and lower diverters extending across the reaction chamber substantially parallel to said lamps and positioned such that all diverters are downstream of the upstream UV lamps, and wherein the upper and lower fluid diverters are positioned to direct fluids toward the uppermost and lowermost ones of the downstream lamps, respectively.
