Abstract
Embodiments of the present disclosure are directed to a device and method for the filtration of gray water from a household. In some embodiments, the gray water can be filtered using a conical rotor and filtration media, which can provide enhanced filtration through the use of Taylor vorticity filtration. The filtered water can have various uses back in the household after filtration.
Claims7
A method for the filtration of gray water, comprising:
- collecting gray water;
- transporting the gray water into a Taylor vorticity filtration device comprising:
- a housing comprising a removable cap, an inlet port, a retentate output port and a filtrate output port;
- a removable filter assembly comprising a filter media and a substrate and one or more circumferential seals, wherein the removable filter assembly is disposed along at least a portion of an inner wall of the housing;
- a rotor coupled to a rotational drive means, and configured to rotate within the housing;
- and
- a gap between the removable filter assembly disposed along at least the portion of the inner wall of the housing and the rotor, such that rotation of the rotor within the housing generates Taylor vortices within the gap;
- filtering the gray water while rotating the rotor within the housing;
- and
- transporting the filtered gray water to a fixture, reservoir, or system configured to utilize or store the filtered gray water.
