Production of alkaline spring water

Abstract

There is set out highly efficient processes for the production of alkaline spring waters. The processes are designed to minimize the use of the additive alkaline formulations used to create the alkalinity in the spring waters and the use of a maximum amount of non-purified spring water in the formulation of the final alkaline spring water product. This is accomplished by dividing the input spring water into at least two portions. One portion undergoes a purification process and the other is not purified. Each portion is tested in increments for the amount of alkaline formulation needed to attain a pH of at least about 10 and designated potassium ion and sodium ion contents. From the testing the amount of the purified spring water and the amount of non-purified spring water needed to be combined to yield a pH of at least about 10 and the designated potassium ion and the sodium ion contents is calculated. It is desired to use a minimum of alkaline formulation to achieve the set Ph and potassium and sodium ion concentration. In this way the more costly components of the alkaline formulation and the purified spring water can be minimized, but yet the taste and stability maintained over a period of time. The processes apply to waters from a single spring and from a plurality of springs.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0025] There are a wide range of available spring waters sources. They have a wide range of various contaminants. Also they will have contents of ions that will interfere with the efficient production of alkaline waters, and in particular alkaline waters having a pH of at least about 10 and a desired potassium ion content of at least about 35 mg/liter and a sodium ion content of about 10 mg/liter. Various dissolved solids in spring waters can affect the amount of potassium ion and sodium ion that is needed to acquire a pH of at least about 10. Such a pH is needed for an effective alkaline water that maintains its alkalinity over an extended period of time and which has an appealing taste.

[0026] At the spring water source the spring water will undergo a filtering to remove large visible inorganic and organic solids. These include fragments of silica, various inorganic oxides and carbonates. Inorganic substances can be minute fragments of surface materials that enter the springs through various voids in the earth's surface.

[0027] The invention is directed to the efficient production of alkaline spring waters from the generally available spring water sources. The source spring waters can come from one spring water source or from a plurality of spring water sources. The efficiencies of the process are derived from not having to purify all of the water from a spring source and from being able to minimize the amount of a purified spring water portion of the spring water source, and being able to minimize the amount of the alkaline formulation that is required to produce the alkaline spring water product having the designated pH and potassium and sodium ion contents. Further, as noted, the spring waters can be from a plurality of springs which is described below. This provides an opportunity for increased efficiencies since a purified water from one spring can be combined with a purified or non-purified water from a different spring for greater efficiency. The end objective is to reach a pH of at least about 10, a desired potassium ion (KOH) content and a desired sodium ion (NaOH) content using a minimum amount of a purified spring water and a minimum amount of alkaline formulation. The alkaline formulation used to achieve a pH of at least about 10 is comprised primarily of NaOH and KOH ions. However, it can contain other ions such as buffers, and compounds that function to release potassium ions and sodium ions over an extended period of time to assist in maintaining the pH of at least about 10 and potassium and sodium ion contents over a period of time.

[0028] The process of alkalizing water from a single spring water source is set out in more detail in the following listing of processing steps:

(1) The effluent water from the single spring is analyzed for hardness and total dissolved solids and divided into two portions. One portion undergoes a purification process. This removes various dissolved and partially dissolved solids that create hardness. Hardness can be created by carbonates. The other portion does not undergo a purification process (non-purified spring water). The purification steps include one or more filterings to remove particles of greater than about 0.0001 micron, an optional reverse osmosis treatment, an optional ultraviolet treatment, and an optional ozone treatment. Other purification techniques can be added as needed. The result is purified spring water. This purified spring water then is treated with an alkaline formulation. This alkaline formulation is comprised primarily of sodium ions and potassium ions and is used to raise the pH of the purified spring water to at least about 10. Potassium ions and sodium ions have a high alkalinity. The alkaline formulation can be essentially any NaOH and KOH containing solution that will raise the pH of the purified spring water and the non-purified spring water to at least about 10. Preferred alkaline formulations are set out in U.S. Pat. No. 5,306,511 to Sang Y. Whang which is incorporated herein by reference. These can have a potassium ion to sodium ion percentage ratio of about 95/5 to 50/50 and preferably about 75/25. A higher potassium ion ratio to sodium ion ratio is preferred.
(3) The alkaline formulation is added to 1 liter samples of each of the purified spring water and the non-purified spring water in set increments and the pH tested after the addition of each increment. The potassium ion and sodium ion contents may also be determined. The desired potassium ion concentration is about 35 mg/liter, and preferably about 40 mg/liter. The sodium ion concentration is about 10 mg/liter and preferably about 13 mg/liter. The amount of alkaline formulation needed to reach the pH of at least about 10 and the desired potassium and sodium ion concentrations is calculated for the purified spring water sample and for the non-purified spring water sample. An objective is to minimize the amount of alkaline formulation required to reach a pH of at least about 10 for a spring water product while using a combination of purified spring water and non-purified spring water. Purified spring water has a higher cost with the result that the use of a higher content of non-purified spring water decreases the final cost of the product spring water and is preferred. The product alkaline spring water will be a blend of the purified spring water and the non-purified spring water based on this testing. It is preferred to use a high content of lower cost non-purified spring water. This is the product alkaline water that is bottled and sold.

[0029] Based on this testing the spring water to be used for the product water the addition of the amount of alkaline formulation in the purified portion and the non-purified portion can be calculated for any amount of product alkaline water that is to be produced. The purified portion can be added containing the calculated amount of alkaline formulation or it can be added without the calculated amount of alkaline formulation and the amount of alkaline formulation added after its addition to the non-purified portion. That is, it is added to the mixture. Whether added separately to the purified portion of spring water or to the mixture after the addition of the purified portion to the non-purified portion the mixture that is to be the product water is tested for pH and for its potassium ion and sodium ion content and final adjustments made by adding more alkaline formulation. Also some additional purified portion and/or non-purified portion can be added as needed in making final adjustments in the product spring water.

[0030] This process is repeated periodically for a spring water source and definitely for any new spring water source. It is an objective to have a consistent alkaline spring water product. This is the case for spring water from a single source or from a plurality of sources. The above process can be extrapolated for use with a plurality of spring sources. It will now be described for a two spring water source. Spring water source A is divided into spring water portion Al to undergo purification and a non-purified spring water portion A2. The portion A1 undergoes a particle filtering to remove the inorganic and organic particles, followed by optional reverse osmosis, UV light filtering and an ozone treatment. The second spring water source is likewise divided into a spring water to be purified water B1 and non-purified spring water B2. The water to be purified undergoes a filtering to remove inorganic and organic particles of greater than 0.0001 micron, an optional reverse osmosis treatment, a UV light filtering, and an optional ozone treatment. Additional purification techniques can be used. The alkaline formulation as described above is then added in increments to one liter samples of the purified spring waters A1 and B1 to determine the minimum amount of alkaline formulation needed to acquire a pH of at least about 10 for each of the purified spring waters A1 and B1. This is repeated for each of the non-purified spring waters A2 and B2. The optimum amount of purified spring waters A1 and/or B1 and non-purified spring waters A2 and/or B2 that should be mixed to produce a product that maximizes the use of non-purified waters A2 and B2 and minimizes the amount of alkaline formulation that is needed to achieve a pH of about 10 or more, a potassium ion content of at least about 35 mg/liter and most preferably at least about 40 mg/liter and a sodium ion content of at least about 10 mg/liter and preferably about 13 mg/liter is calculated. The mixtures can be any of A1-A2; A1-B2; B1-A2; or B1-B2. This is determined by the incremental addition of alkaline formulation to the purified spring waters A1 and B1 and to the non-purified spring waters A2 and B2. The most efficient combination is determined and then chosen and bottled as the alkaline water product.

[0031] This description of a plurality of spring water sources has been shown with two spring water sources. However, it can be extrapolated to three, four or more spring water sources. The procedures will be the same for each spring water source. However, there will be more mixing options to achieve the use of a maximum amount of non-purified water and a minimum amount of alkaline formulation. The number of spring water sources to be used will be determined by the volume of alkalized spring water product needed. Also for the health and stability of spring water sources it is advisable not to over draw water from a spring source. A spring source can efficiently deliver a certain amount of water per day. Springs get replenished over time and the draw rate from the spring should not exceed the replenishment rate of the spring.
