Abstract
A water purification system (100) including an inlet (110) configured to accept a flow of water (105) is provided. The system (100) includes a KDF filtration stage (120) fluidly connected to the inlet (110) and including a metal alloy including elemental copper and elemental zinc. The system (100) includes a reverse osmosis stage (140) fluidly connected to the KDF stage (120). The system (100) also includes an outlet (150) fluidly connected to the reverse osmosis stage (140) and configured to output a flow of purified water (155). The reverse osmosis stage (140) is downstream of the KDF stage (120). A method of purifying water is also provided.
Claims10
A water purification system comprising:
- an inlet configured to accept a flow of water;
- a KDF filtration stage fluidly connected to the inlet and comprising a metal alloy comprising elemental copper and elemental zinc;
- a reverse osmosis stage fluidly connected to the KDF stage;
- and
- an outlet fluidly connected to the reverse osmosis stage and configured to output a flow of purified water;
- wherein the reverse osmosis stage is downstream of the KDF stage.
A water purification system comprising:
- an inlet configured to accept a flow of water;
- a KDF filtration stage fluidly connected to the inlet and comprising a metal alloy that is a homogeneous mixture that is about 40 wt % to about 90 wt % elemental copper and about 10 wt % to about 60 wt % elemental zinc, wherein the elemental copper and the elemental zinc together are about 99.5 wt % to about 100 wt % of the metal alloy;
- a reverse osmosis stage fluidly connected to the KDF stage;
- a diatomite stage fluidly connected to the reverse osmosis stage, the diatomite stage comprising diatomite-based porous ceramic filtration media;
- and
- an outlet fluidly connected to the diatomite stage and configured to output a flow of purified water;
- wherein the reverse osmosis stage is downstream of the KDF stage, and the diatomite stage is downstream of the reverse osmosis stage.
A method of purifying water, the method comprising:
- flowing the water into an inlet configured to accept the flow of water;
- flowing the water from the inlet to a KDF filtration stage fluidly connected to the inlet and comprising a metal alloy comprising elemental copper and elemental zinc;
- flowing the water from the KDF filtration stage to a reverse osmosis stage fluidly connected to the KDF stage;
- flowing the water from the KDF filtration stage to an outlet fluidly connected to the reverse osmosis stage and configured to output a flow of purified water;
- and
- flowing the purified water from the outlet;
- wherein the reverse osmosis stage is downstream of the KDF stage.
