How Do You Add Salt to Reverse Osmosis Water?

Published in Water Treatment 3 mins read

To add salt to reverse osmosis (RO) water, it's generally done to remineralize the water after the RO process strips away natural minerals. Here's how:

Why Add Salt to Reverse Osmosis Water?

Reverse osmosis water is very pure, but it lacks the natural minerals that contribute to taste and potential health benefits. Adding a small amount of salt can:

  • Improve the taste of the water.
  • Replenish some electrolytes.

How Much Salt to Add:

The amount of salt to add depends on your preferences and the type of salt you're using. Here's a general guideline:

  • Himalayan Pink Salt: A popular choice due to its mineral content. Use 1/4 teaspoon per gallon of RO water.
  • Other Salts (Sea Salt, Table Salt): Start with a small pinch per glass and adjust to taste.

Steps for Adding Salt:

  1. Measure the Salt: Use a clean measuring spoon for accuracy when adding to a gallon. Use a pinch for individual glasses.
  2. Add to Water: Pour the measured salt into your reverse osmosis water.
  3. Stir Well: Ensure the salt is completely dissolved.
  4. Taste Test: Sample the water and adjust the amount of salt as needed to achieve your desired taste. It's always best to start with less and add more.

Important Considerations:

  • Use High-Quality Salt: Opt for Himalayan pink salt or a good quality sea salt for mineral content. Avoid iodized table salt if you're primarily looking for remineralization.
  • Start Small: It's easier to add more salt than to remove it, so begin with a small amount and adjust to your liking.
  • Health Conditions: If you have any health conditions (such as high blood pressure) that require you to limit your sodium intake, consult with your doctor before adding salt to your water.
  • Purpose: Consider why you are adding salt. Is it purely for taste, or are you seeking the benefits of electrolytes or trace minerals? This will influence your salt choice.

By following these guidelines, you can effectively add salt to reverse osmosis water to improve its taste and potentially add some minerals back into your drinking water.
