The most direct way to improve Total Dissolved Solids (TDS) in water, particularly after using a Reverse Osmosis (RO) system which removes minerals, is to add minerals back into the water.
Here's a breakdown of methods:
Methods to Increase TDS in Water
1. Using Mineral Drops or Additives
-
Description: Mineral drops are concentrated solutions containing essential minerals like calcium, magnesium, potassium, and sodium. Adding these drops to purified water effectively increases the TDS level and replenishes beneficial minerals.
-
How to Use: Follow the instructions on the mineral drop product. Generally, a few drops are added per gallon or liter of water.
-
Benefits: Convenient, precise control over mineral content, and provides beneficial minerals.
-
Where to Buy: Health food stores, online retailers (e.g., Amazon), and water filtration specialty shops.
2. Blending with Tap Water
-
Description: Mixing RO or distilled water with tap water is a simple way to increase TDS. Tap water naturally contains minerals.
-
How to Use: Experiment with different ratios of RO water to tap water until you achieve the desired TDS level and taste. Use a TDS meter to measure the TDS.
-
Benefits: Cost-effective, easy to implement.
-
Considerations: Ensure your tap water is safe for consumption and does not contain harmful contaminants. Test your tap water regularly.
3. Remineralization Filters
-
Description: These filters are often installed after an RO system and contain minerals that dissolve into the purified water as it passes through, increasing the TDS.
-
How to Use: Install the filter according to the manufacturer’s instructions.
-
Benefits: Automatic remineralization, consistent mineral content.
-
Considerations: Requires filter replacement periodically.
4. Mineral Stones
-
Description: Certain mineral stones, like those containing calcium or magnesium, can be added to water to slowly increase TDS.
-
How to Use: Place the stones in the water and allow them to sit for a period of time. Test the water regularly to monitor TDS levels.
-
Benefits: Natural and long-lasting.
-
Considerations: The rate of mineral dissolution may be slow and difficult to control.
TDS Target Levels
While there's no universally agreed-upon "ideal" TDS level, many people find that water with a TDS between 100-300 ppm tastes best. Reverse Osmosis water typically has a TDS close to 0, therefore the above methods can increase the TDS to a more desirable level.
Important Considerations:
- Water Safety: Ensure any method you use introduces safe and beneficial minerals.
- TDS Meter: Use a TDS meter to accurately measure the TDS level of your water. This helps you control the mineral content and ensure you reach your desired level.
- Taste Preference: Experiment with different methods and mineral additions to find what tastes best to you.
In summary, the most effective way to improve the TDS of water after purification is to add minerals back using mineral drops, blending with tap water, or utilizing remineralization filters.
