Abstract
A liquid treatment system that may be self-powered includes a filter 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 liquid treatment system may include a first liquid flow path that provides treated liquid, and a second liquid flow path that provides untreated liquid. The filter and the hydro-power generator are included in the first liquid flow path so that electric power is generated by the hydro-power generator when liquid flows through the first liquid flow path.
