How to Increase pH of RO Water

Water’s pH level serves as a gauge for its acidity or alkalinity. The pH scale ranges from 0 to 14, with a neutral pH value of 7. Acidic water has a pH value below 7, whereas alkaline water has a pH value over 7. The World Health Organization (WHO) recommends that drinking water have a pH between 6.5 and 8.5.

RO water is normally mildly acidic, with a pH range of 5 to 7. This is mostly due to the presence of carbon dioxide (CO2) in RO water, which dissolves in water to generate carbonic acid and lowers pH levels. When RO water reacts with CO2, its acidity increases in proportion to how pure it is.

Even though drinking water that is slightly acidic may not offer any severe health dangers, your body and your appliances may suffer as a result. For instance, acidic water could

  • Increase the risk of exposure to lead, copper, iron, and other dangerous elements by allowing metals from pipes and faucets to leach.
  • Appliances and fixtures made of metal that have corroded, such as kettles, coffee makers, dishwashers, and water heaters, have a shorter lifespan and less efficiency.
  • Enamel erosion and cavities are brought on by weakening your teeth’s enamel.
  • By removing the natural oils and moisture from your skin and hair, irritate them.
  • Changing the pH balance in your stomach and intestines might have an impact on your metabolism and digestion.

To make RO water more alkaline and healthier for drinking and other applications, it may therefore be advantageous to raise the pH of the water. In this post, we’ll demonstrate four quick but efficient ways to accomplish that.

What is the best pH level for RO water?

Method 1: Add Baking Soda

A little amount of baking soda (sodium bicarbonate) can be added to RO water to raise its pH, which is one of the simplest and least expensive methods to do so. A naturally occurring alkaline material, baking soda can raise the pH of water and neutralise acidity.

This approach requires the following:

  • Baking soda one teaspoon worth
  • RO water in a gallon
  • A large jug or container
  • One made of wood
  • A pH metre or test kit

The steps are as follows:

  • Add RO water to the pitcher or container.
  • A teaspoon of baking soda should be added, and it should be thoroughly mixed in with a wooden spoon until it dissolves.
  • Utilise the test kit or metre to determine the pH of the water. The ideal range is 6.5 to 8.5.
  • Add more baking soda gradually until you achieve the target level if the pH is still too low. Avoid adding too much baking soda since it may cause the water to taste harsh or salty.
  • Enjoy your alkaline RO water now, or keep it in the fridge in a sealed bottle for later use.

Method 2: Add Mineral Drops

Installing a remineralization filter as the last step after the RO process is a more long-lasting and practical technique to raise the pH of RO water. A remineralization filter is a cartridge that includes alkaline minerals that can dissolve in water and increase its pH level, like coral calcium, magnesium oxide, and calcium carbonate.

This approach requires the following:

  • A filter for remineralization
  • An appropriate RO system
  • A DIY kit or a plumber

The steps are as follows:

  • Pick a remineralization filter that is affordable and compatible with your RO system. Both online and offline retailers carry a wide variety of brands and models. Be sure to study the product’s features, reviews, and warranty before you purchase it.
  • Follow the manufacturer’s or the plumber’s installation instructions for installing the remineralization filter. Typically, you’ll need to use tubing and fittings to connect the filter to your RO system’s faucet or tank.
  • To clear the cartridge of any dust or debris, flush the remineralization filter for a few minutes.
  • Utilise the test kit or metre to determine the pH of the water. The ideal range is 6.5 to 8.5.
  • Enjoy your alkaline RO water now, or keep it in the fridge in a sealed bottle for later use.

Method 4: Add Himalayan Pink Salt

Himalayan pink salt is a natural and healthful approach to raise the pH of RO water. In addition to over 80 trace minerals, such as calcium, magnesium, potassium, sodium, and bicarbonate, Himalayan pink salt is a sort of rock salt that can balance the pH and make the water more alkaline.

This approach requires the following:

  • A dash of pink Himalayan salt
  • RO water in a gallon
  • A large jug or container
  • One made of wood
  • A pH metre or test kit

The steps are as follows:

  • Add RO water to the pitcher or container.
  • Himalayan pink salt should be added in a pinch; mix well with a wooden spoon until all of the salt dissolves.
  • Utilise the test kit or metre to determine the pH of the water. The ideal range is 6.5 to 8.5.
  • Add more Himalayan pink salt gradually until the pH is where you want it to be if it’s still too low. It’s important to avoid using too much Himalayan pink salt, which could give the water a mineralized or salty taste.
  • Enjoy your alkaline RO water now, or keep it in the fridge in a sealed bottle for later use.
How to Increase pH of RO Water

Why is pH Important for Drinking Water?

The pH level of drinking water is important for several reasons. First, it affects the taste, smell, and appearance of water. Water with a low pH may have a sour or metallic taste, a musty or rotten smell, and a cloudy or coloured appearance. Water with a high pH may have a bitter or chalky taste, a bleach-like smell, and a slippery feel.

Second, it influences the availability of minerals and nutrients in water. Water with a low pH may leach metals from pipes and faucets, such as lead, copper, iron, and zinc, which can be harmful to health in high doses.

Water with a high pH may reduce the absorption of essential minerals, such as calcium and magnesium, which are important for bone health and muscle function.

Third, it affects the health of the human body and its organs. Water with a low pH may cause dental erosion and cavities by weakening the enamel of the teeth. It may also irritate the skin and hair by stripping away natural oils and moisture.

It may affect the digestion and metabolism by altering the pH balance of the stomach and intestines. It may even increase the risk of certain diseases, such as cancer, heart disease, diabetes, and acid reflux, by creating an acidic environment in the body that promotes inflammation and oxidative stress.

Water with a high pH may have some health benefits, such as preventing metal leaching and corrosion, protecting dental health, hydrating skin and hair, improving digestion and metabolism, and enhancing immunity and energy.

However, these benefits are not well-established by scientific evidence, and drinking water that is too alkaline may also have some negative effects, such as causing nausea, vomiting, diarrhoea, muscle twitching, confusion, and numbness.

Therefore, it is recommended to drink water that has a pH level between 6.5 and 8.5, according to the World Health Organization (WHO). This range is considered safe and optimal for human consumption.

Drinking water that falls outside this range may not necessarily be unsafe, but it may have some undesirable effects on your water quality and your health.

Conclusion

Increasing the pH of RO water can make it healthier and tastier for drinking and other uses. You can use any of the four methods we discussed above to make your RO water more alkaline and balanced.

However, before you try any of these methods, make sure to test the pH level of your RO water first using a reliable test kit or metre. This will help you determine how much you need to adjust the pH level and avoid making it too high or too low.

Also, remember that increasing the pH of RO water does not mean that it is safe from contamination or bacteria. You still need to maintain your RO system regularly and replace the filters as needed to ensure optimal performance and quality.

We hope this article has helped you learn how to increase pH of RO water easily and effectively. Please don’t hesitate to share any questions or comments you may have by leaving them below.

FAQ’s

What is the best way to raise pH in water?

The ideal method for increasing water’s pH relies on the particular circumstances and preferences. Alkaline chemicals like baking soda, mineral drops, or Himalayan pink salt are some useful techniques, nevertheless. The pH can also be raised by utilising a remineralization filter as the last step in the reverse osmosis (RO) procedure. To prevent over-alkalinizing the water, each procedure should be used cautiously while measuring the pH level along the way.

Why is my RO water pH so low?

The removal of alkaline minerals during the reverse osmosis process is the main cause of the low pH of RO water. While successfully removing impurities, RO systems also remove helpful minerals like calcium, magnesium, and potassium. The pH is further lowered when RO water reacts with carbon dioxide in the air to create carbonic acid.

What is the best pH level for RO water?

The World Health Organization (WHO) states that the ideal pH range for RO water is between 6.5 and 8.5. This range is regarded as safe and acceptable for drinking water and is considered neutral to slightly alkaline.

What causes high pH in RO water?

Having a high pH in RO water is less often, but it might happen if the water supply had a high pH to begin with or if too many alkaline minerals were added during the remineralization process. When utilising techniques to boost alkalinity, it’s critical to keep an eye on the pH because excessively high pH levels can have an impact on the water’s flavour and safety.
