1. An ultraviolet cyclonic fluid dosing system, comprising:
a dosing chamber comprising:
an upper cylindrical cyclonic chamber defining a central axis and having a tangential fluid inlet and a cylindrical fluid outlet, wherein the cylindrical fluid outlet has a central axis that is aligned with the central axis of the cylindrical cyclonic chamber, wherein the cylindrical fluid outlet extends downward from along the central axis to define a fluid outlet that is lower than the fluid inlet;
a lower conical cyclonic chamber coupled to the upper chamber and having a central axis that is aligned with the central axis of the upper cylindrical chamber;
an array of ultraviolet-light emitters disposed in the upper chamber along a circumferential perimeter of the cylindrical fluid outlet, wherein the ultraviolet-light emitters of the array point towards the lower chamber; and
an ultraviolet-light emitter disposed in the lower chamber along the central axis, wherein the ultraviolet-light emitter points towards the upper chamber, wherein the emitters are configured to dose a fluid material with ultraviolet light, wherein the fluid material enters the fluid inlet and travels through a helical path through the dosing chamber.
