Self-powered miniature liquid treatment system
View Patent ↗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.
1. A liquid treatment system, comprising:
a first liquid flow path that provides treated liquid and a second liquid flow path that provides untreated liquid;
a filter configured to be part of the first liquid flow path; and
a power generation module configured to include a first passage that is a portion of the first liquid flow path and a second passage that is a portion of the second liquid flow path,
wherein electric power is generated by the power generation module only upon a flow of liquid through the first liquid flow path a first outlet from the first liquid flow path to discharge treated liquid and a second outlet from the second liquid flow path that is independent of the first outlet to discharge untreated liquid.
2. The liquid treatment system of claim 1 , further comprising a processor configured to monitor the electric power generated by the power generation module, the processor configured to determine a flow rate of liquid through the first liquid flow path as a function of the electric power generated.
3. The liquid treatment system of claim 1 , wherein the power generation module comprises a nozzle and a hydro-generator, wherein the hydro-generator rotates within the first liquid flow path in response to the flow of liquid in the first liquid flow path being extruded as a stream of liquid from the nozzle.
4. The liquid treatment system of claim 1 , further comprising an ultraviolet dosing system configured to be part of the first liquid flow path, the electric power generated by the power generation module supplied to the ultraviolet dosing system.
5. The liquid treatment system of claim 4 , wherein the power generation module comprises a hydro-generator rotationally disposed in the first liquid flow path and the processor is configured to determine a rotational speed of the hydro-generator as a function of the electric power generated and energize the ultraviolet dosing system with the electric power when the rotational speed of the hydro-generator is within a determined range.
6. A liquid treatment system, comprising: a first liquid flow path that provides treated liquid and a second liquid flow path that provides untreated liquid; a filter configured to be part of the first liquid flow path; and a power generation module configured to include a first passage that is a portion of the first liquid flow path and a second passage that is a portion of the second liquid flow path, wherein electric power is generated by the power generation module only upon a flow of liquid through the first liquid flow path and a processor configured to monitor the electric power generated by the power generation module, the Processor configured to determine a flow rate of liquid through the first liquid flow path as a function of the electric power generated, wherein the processor is configured to track usage of the filter as a function of the electric power generated.
7. The liquid treatment system of claim 1 , wherein the power generation module includes a rotor and a stator disposed in the first passage, the rotor rotatable around the stator to generate electric power in response to an extruded stream of the flow of liquid within the first passage.
8. The liquid treatment system of claim 1 , further comprising a switch mechanism, the switch mechanism configured to toggle between the first and second liquid flow paths.
9. The liquid treatment system of claim 1 , wherein the first passage is formed inside an outer housing included in the power generation module and the second passage is formed outside the outer housing.
10. A liquid treatment system, comprising: a first liquid flow path that provides treated liquid and a second liquid flow path that provides untreated liquid; a filter configured to be part of the first liquid flow path; and a power generation module configured to include a first passage that is a portion of the first liquid flow path and a second passage that is a portion of the second liquid flow path, wherein electric power is generated by the power generation module only upon a flow of liquid through the first liquid flow path and a lever and a valve core, the valve core having a first cavity forming part of the first liquid flow path and a second cavity forming part of the second liquid flow path, wherein the first and second cavities are separate and independent liquid flow paths that are selectable with the lever.
11. The liquid treatment system of claim 1 , wherein the filter comprises activated carbon.
