Bottled Drinking Water pH

Is there any way to increase the pH of water to 9 while maintaining TDS at 30 in mineral water?

How can this be done after reverse osmosis? Which technology or chemicals can be used to achieve this?

1. See these two videos on the topics: pH of mineral waters, below:

2. Dear Muhammad Naeem,

   We are a ​France based ​water treatment ​company ​providing ​solutions for ​the bottling ​industries (​visit http://​www.ice-water-​treatment.com/​en/) over the ​world.
   We are familiar with mineral water stakes, should the mineralisation be natural or controlled. Our solutions are deployed for many ​mineral waters, and pH often comes as a specific criteria. We could ​propose some ​tailor-made ​process ​according to ​you water ​characteristics.​ Feel free to ​transmit me ​your data, ​which I would ​forward to the ​sales engineer ​in charge with ​your geographic ​area. ​
   I hope that we talk soon.

   The above might partially answer your question.

   TDS could be higher,without problem.

   But mineral water has defined parameters,and modified water is just bottled water,and may not be possibly qualified as mineral water. Moreover,in the case of artificial water or process water from RO,it is advised to add vital minerals.

4. You can not modify Mineral water! (only aeration to remove the excess iron, and max 1 micron filter to remove sediment/sand). If you do some modifications - you can not call it Mineral water, but Drinking water. Please clarify first what exactly you want to produce Mineral (premium) or cheap modified Drinking water.

5. According to WHO criteria, the ideal pH level of drinking water is often in the range of 6.5 to 9.5. An aesthetic ​​objective of ​​≤500 mg/​​L has been ​​established ​for ​total ​dissolved ​​solids (TDS) in ​​drinking water ​​by WHO.

   The TDS is directly proportional to pH, for mineral water TDS is 30 ppm. But each country different parameters. according to USA the TDS is 500 ppm. One of the most misunderstood aspects of water is it pH level. In recent times, there are many claims being made about the advantages of drinking alkaline water that is said to be rich with antioxidants, and has the ability to slow down degenerative diseases and slow down ageing. According to some doctors, our body is anyway designed to adjust to its ‘optimal pH balance’. Once alkaline water enters your stomach, your body simply pours in greater amounts of acid to neutralize it.

6. Reverse osmosis water is not recommended for long-term drinking purposes. It's  "synthetic water" and does not exist in nature. It's devoid of the important trace minerals needed by the body. It's sometimes called "hungry water" in that it steals vital minerals from the body to make itself whole. You will need to add minerals such as calcium and magnesium and this will increase the TDS. Higher TDS can be a good thing.

   1. Reverse osmosis water is not recommended for long-term drinking purposes. 

      How?

   2. What about very pure natural glacier water ? The Norvegian natural water VOSS has a TDS of 44ppm !

7. The question seems questionable !

   One side you say that its a Mineral Water and say the TDS is 30ppm ! Which Mineral Water for Drinking in the World has TDS 30ppm. Please purchase any Mineral Water Bottle and Check the TDS Levels on it which is clearly printed on almost every company's mineral water bottle. 

   But what I feel if you are influenced with the theory which is prevailing now to have drinking water on Alkaline Side which could have some health benefit, then there is another case. So you can increase pH by adding as per prescribed by many fellows here but there could be a compromise between taste and may be odor by adding some chemicals. 

   Permissible ​range of TDS in ​drinking water: ​  Different ​government ​has ​different ​regulations for ​the TDS level. ​The U.S. EPA ​sets the ​maximum ​contaminant ​level for TDS ​500 ppm where ​as WHO has ​different ​prescribe ​limits. ​

   An aesthetic ​objective of ​≤500 mg/​L has been ​established for ​total dissolved ​solids (TDS) in ​drinking water ​by WHO. At ​higher levels, ​excessive ​hardness, ​unpalatability, ​mineral ​deposition and ​corrosion may ​occur. At low ​levels, however,​ TDS ​contributes ​to the ​palatability of ​water. ​Most people ​think of TDS as ​being an ​aesthetic ​factor. In a ​study by the ​World Health ​ ​Organization, a ​panel of ​tasters came to ​the following ​conclusions ​about the ​preferable ​level of ​TDS in water: ​  ​

   Taste of ​Water with ​Different TDS ​Concentrations ​
   Level of TDS (​milligrams per ​litre) ​	Rating
   Less than 300	Excellent
   300 - 600	Good
   600 - 900	Fair
   900 - 1,200	Poor
   Above 1,200	Unacceptable

8. You may want to consider electrolysis. The water is alkaline at the cathode and has a higher pH. The "alkaline" water can be siphoned at the cathode. It's an electrochemical process. You may look-up "ionizers" on the web. This said, I do not endorse the health and other claimed benefits of "alkaline" water and the effectiveness of "Ionizing" home appliances. 

   The other processes e.g. mineralization will affect the TDS.

9. You can add some dolomite lime for Ca and Mg alkalinity and a touch of NaOH if you want a pH boost for some reason,  You are not allowed to treat mineral water and still label it mineral water. Check on the Water Codex Alimentarius requirements.

10. you can dose morpholine in RO permeate water,TDS will be remain same but ph increase . This should be dosed minimum .

    1. No morpholine in drinking water!!!!

11. Why do you want to do this?

    1. Quite.

12. You can try adding baking soda to the water. Getting the water to a pH of 9 is possible but you must consider the taste of the water. 

    After treating water with RO you loose trace minerals from the water. It is very essential to introduce these back into the water and can be done by passing the water through a remineralizer. 

    Many companies in the U.S. sell remineralizing cartridges.
