Ultraviolet lamps are positioned in the fluid flow and arrays of triangularly shaped mixing elements are arranged at spaced intervals along the length of each lamp, wherein the plurality of arrays of triangularly shaped mixing elements create four vortices surrounding each elongated member forming a square array of vortices. ## Claims ### Claim 1 An apparatus for mixing at least one fluid flowing through a fluid system, comprising: an array of rows and columns of elongated members wherein each elongated member is horizontally aligned with elongated members in adjacent columns and vertically aligned with elongated members in adjacent rows of elongated members, and wherein the axis of each elongated member is substantially aligned with the direction of fluid flow; and a plurality of arrays of mixing elements arranged at spaced intervals along the length of each elongated member, wherein the plurality of arrays of mixing elements create four vortices surrounding each elongated member forming a square array of vortices. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein each elongated member is an ultraviolet light source. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the mixing elements include mixing elements having a triangular shape with one apex pointing upstream and at an angle to the direction of flow. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the mixing elements include mixing elements having a half triangular shape and wherein the half triangular shape mixing elements are arranged along the elongated member in areas of the apparatus not surrounded by four elongated members. ### Claim 5 (depends on 3) The apparatus of claim 3, wherein the fluid system is an open channel system, and wherein mixing elements are mounted on horizontal support rods. ### Claim 6 (depends on 3) The apparatus of claim 3, wherein the fluid system is an open channel system, and wherein mixing elements are mounted on vertical support rods. ### Claim 7 (depends on 3) The apparatus of claim 3, wherein the fluid system is an open channel system, and wherein the elongated members are vertically arranged in racks for removal from the channel and the mixing elements are mounted on vertical support rods separately removable from the racks. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein each rack includes a frame having spaced apart vertical bars, wherein the spaced apart vertical bars create an open area around the elongated members. ### Claim 9 (depends on 2) The apparatus of claim 2, wherein the mixing elements include mixing elements having a triangular shape whereby the leading apex is removed. ### Claim 10 (depends on 3) The apparatus of claim 3, where the fluid system is a closed channel system having the apparatus disposed in a cylindrical vessel. ### Claim 11 A method for mixing at least one fluid flowing through a fluid system: submersing an array of rows and columns of elongated members in the fluid flow wherein each elongated member is horizontally aligned with elongated members in adjacent columns and vertically aligned with elongated members in adjacent rows of elongated member, and wherein the axis of each elongated member is aligned with the direction of fluid flow; arranging a plurality of arrays of mixing elements at spaced intervals along the length of each elongated member, wherein the plurality of arrays of mixing elements create four vortices surrounding each elongated member forming a square array of vortices. ### Claim 12 (depends on 11) The method of claim 11, wherein each elongated member is an ultraviolet light source. ### Claim 13 (depends on 12) The method of claim 12, wherein the mixing elements include mixing elements having a triangular shape with one apex pointing upstream and at an angle to the direction of flow. ### Claim 14 (depends on 13) The method of claim 13, wherein the mixing elements include mixing elements having a half triangular shape and wherein the half triangular shape mixing elements are arranged along the elongated member in areas of the apparatus not surrounded by four elongated members. ### Claim 15 (depends on 13) The method of claim 13, wherein the fluid system is an open channel system, and wherein mixing elements are mounted on horizontal support rods. ### Claim 16 (depends on 13) The method of claim 13, wherein the fluid system is an open channel system, and wherein mixing elements are mounted on vertical support rods. ### Claim 17 (depends on 13) The method of claim 13, wherein the fluid system is an open channel system, and wherein the elongated members are vertically arranged in racks for removal from the channel and the mixing elements are mounted on vertical support rods separately removable from the racks. ### Claim 18 (depends on 17) The method of claim 17, wherein each rack includes a frame having spaced apart vertical bars, wherein the spaced apart vertical bars create an open area around the elongated members. ### Claim 19 (depends on 12) The method of claim 12, wherein the mixing elements include mixing elements having a triangular shape whereby the leading apex is removed. ### Claim 20 (depends on 13) The method of claim 13, where the fluid system is a closed channel system having the apparatus disposed in a cylindrical vessel.
