Abstract

A method for providing a safe and healthy water and water-based product, comprising: testing pretreated reverse osmosis water to determine whether it meets a first set of pre-defined specifications; introducing a pre-defined nutrient composition into the water, wherein the predefined nutrient composition comprising one or more of mineral nutrients, trace elements and nutritional supplements; testing the water to determine whether it meets a second set of predefined specifications; and disinfecting the water along with its container by UV irradiation from a UV light source to obtain a water product.

First claim

What is claimed is:

1. A method for providing a water product for human consumption, the method comprising:
testing pretreated reverse osmosis water to determine whether it meets a first set of pre-defined specifications;
introducing a nutrient composition into the tested pretreated reverse osmosis water, wherein the nutrient composition includes one or more of mineral nutrients, trace elements and nutritional supplements;
dispensing the water having the introduced nutrient composition into a container;
testing the dispensed water to determine whether it meets a second set of pre-defined specifications;
disinfecting the tested water in and along with its container by UV irradiation from a UV light source to obtain a water product; and
removing the container containing the disinfected water from the UV light source for consumption.

2. The method of claim 1 , wherein testing the water before or after dispensing includes testing the water to determine whether the water meets pre-defined specifications with respect to electrical conductivity or TDS or pH.

3. The method of claim 1 , wherein disinfecting the tested water comprises irradiation with UV light for a period from about 1 second to 10 minutes.

4. The method of claim 1 , wherein introducing a nutrient composition includes introducing mineral nutrients selected from ions comprising: Ca 2+ , HCO 3− , Mg 2+ , NO 3 2− , K + , Na + , NO 3 − , SO 4 2− .

5. The method of claim 1 , wherein introducing a nutrient composition includes introducing trace elements selected from elements comprising: B, Cu, I, Fe, Mn, Se, and Zn.

6. The method of claim 1 , wherein introducing a nutrient composition includes introducing vitamins.

7. The method of claim 1 , wherein introducing a nutrient composition includes introducing the nutrient composition in a sealed package.

8. The method of claim 7 , wherein dispensing the water and nutrient composition includes dispensing 10 mL to 5.0 L of water having nutrient compositions added from a sealed package.

9. The method of claim 1 , wherein disinfecting the tested water in and along with its container includes obtaining a water product comprising less than 1 count/L of E. Coli.

10. The method of claim 1 , wherein the first set of pre-defined specifications comprises one or more of a less than 0.001 mg/L of Hg, less than 0.01 mg/L of Pb, or less than 0.060 mg/L of CH 3 Cl.

11. The method of claim 1 , wherein disinfecting the tested water in and along with its container includes obtaining a water product that is substantially free of chemical disinfectants.

12. The method of claim 1 , wherein introducing a nutrient composition into the water comprises introducing the nutrient compositions in the form of solution, suspension, dry powder, pellets, or capsules.
