Abstract
A system and method for washing items with water includes a water inlet and a container for receiving the items to be washed. The system comprises a water purification apparatus for purifying water introduced through said water inlet to produce purified water. The water purification apparatus comprises at least one filter for filtering off particulate solids, a reverse osmosis device, and at least one deionizing filter. The system further comprises a reservoir for storing purified water produced by the water purification apparatus, said reservoir being connected to said water purification apparatus and said container, so that the items are washable inside the container with the purified water.

A system for washing items with purified water, comprising a water inlet and a container for receiving the items to be washed, wherein the system comprises a water purification apparatus for purifying water introduced through said water inlet to produce purified water, the water purification apparatus comprising:
- at least one filter for filtering off particulate solids,
- a reverse osmosis device, and
- at least one deionizing filter comprising a tank with deionizing material, wherein the at least one deionizing filter is configured to be a mechanical filter, wherein the reverse osmosis device is arranged between the at least one filter for filtering off particulate solids and the tank with the deionizing material, and,
- wherein the system further comprises a reservoir for storing purified water produced by the water purification apparatus, said reservoir being connected to said water purification apparatus and said container, so that the items are washable inside the container with the purified water.
A method for washing items with purified water, comprising the steps of:
- a) conducting water from a water supply to a water inlet of a system for washing said items,
- b) conducting said water to a water purification apparatus for purifying said water,
- c) filtering off particulate solids from the water inside the water purification apparatus,
- d) purifying the water by means of reverse osmosis inside the water purification apparatus,
- e) after step d) filtering the water through at least one deionizing filter inside the water purification apparatus, the deionizing filter comprising a tank with a deionizing material, wherein the at least one deionizing filter is configured to be a mechanical filter,
- f) conducting the purified water to a reservoir for storing the purified water,
- g) conducting the purified water from the reservoir to a container with the items to be washed, and
- h) washing the items inside the container with the purified water.
