Abstract
A water purification system is provided that includes a pre-filtration system for pre-filtering water, a first pump, a nano-filtration membrane configured to separate pre-filtered water into nano-filtered water and effluent, a holding tank, and a second pump. The first pump is operable for pumping pre-filtered water through the nano-filtration membrane, and the second pump is operable for pumping nano-filtered water from the holding tank into the plumbing of a building.
Claims39
A water purification system, comprising:
- a pre-filtration system for pre-filtering water;
- a first pump;
- a nano-filtration membrane configured to separate pre-filtered water into nano-filtered water and effluent;
- a holding tank;
- and
- a second pump;
- wherein the first pump is operable for pumping pre-filtered water through the nano-filtration membrane, and the second pump is operable for pumping nano-filtered water from the holding tank into the plumbing of a building.
A water filtration unit for connecting to a water main, a holding tank, and the plumbing of a building, comprising:
- a pre-filtration system operable for pre-filtering water received from the water main;
- a first pump;
- a nano-filtration membrane configured to separate pre-filtered water into nano-filtered water and effluent;
- and
- a second pump;
- wherein the first pump is operable for pumping pre-filtered water through the nano-filtration membrane, and the second pump is operable for pumping nano-filtered water from the holding tank into the plumbing of a building.
A holding tank for a water purification system for a building, comprising:
- a reservoir operable for storing water, and configured to have a low center of gravity;
- an inlet operable for receiving filtered water from a water filtration unit;
- an outlet configured substantially near the bottom of the reservoir.
A water purification system, comprising:
- a holding tank;
- and
- a water filtration unit, including:
- a pre-filtration system operable for pre-filtering water;
- a first pump;
- a nano-filtration membrane configured to separate pre-filtered water into nano-filtered water and effluent;
- and
- a second pump.
A method of purifying water for a building, comprising:
- pre-filtering water with a pre-filtration system operable for removing sediment from and dechlorinating water;
- separating pre-filtered water into nano-filtered water and effluent with a nano-filtration membrane;
- storing the nano-filtered water in a holding tank;
- and
- pumping the nano-filtered water from the holding tank into the plumbing of a building.
