1. A method of treating liquid with a liquid treatment system, the method comprising:
- initiating a flow of liquid through a liquid treatment system;
rotating a hydro-generator with the flow of liquid to generate electric power;
monitoring to determine the revolutions-per-minute of the hydro-generator;
energizing an ultraviolet light source with the electric power generated by the hydro-generator only when the revolutions-per-minute of the hydro-generator enters a determined range; and
subjecting the flow of liquid to ultraviolet energy generated by the ultraviolet light source.

Abstract
A liquid treatment system that may be self-powered includes a filter, an ultraviolet light source and a hydro-generator. A flow of liquid may be filtered with the filter and used to rotate the hydro-generator to generate electric power. The ultraviolet light source may be energized by the electric power generated by the hydro-generator when the revolutions-per-minute or the magnitude of electric power of the hydro-generator enters a determined range. The flow of liquid may be subject to ultraviolet energy generated by the ultraviolet light source. It may be indicated when the ultraviolet light source reaches dose.
