Abstract
An apparatus and method for mixing at least one fluid flowing through a fluid system using ultraviolet light to control organisms. 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.
Claims20
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.
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.
