What Is The TDS Value For Drinking Water?

We have already told you about the TDS meters, TDS controllers, and whatnot. Now, The question raising in everybody’s mind must be, “What Is The TDS Value For Drinking Water?”

In a perfect world, the pH level of extremely pure water is 7. Moreover, anything that has a pH level below 7 is considered to be acidic. The reason behind it is that the figure over 7 tends to make the water alkaline and not just fit for drinking.

Therefore, it is important to check the pH of the water before you consume it. The absolute pH value for drinking water should be in a range somewhere between 7 to 8.5.

Although, water with a pH level of 7 is crystal pure, but does not have a good taste. In fact, the water is tasteless, odorless, and colorless. This is the reason, people require some amount of TDS and minerals to be added to the water. By doing so, the taste of the water improves.

Consequently, the TDS controller and mineralizers come with their own importance and workings.

The quality of the water depends on the TDS level of the water. TDS value for drinking water is distributed in levels. Check below for a better understanding.

TDS Value For Drinking Water

TDS Levels Quality Of Water
Below 300 Excellent
Between 300 to 600 Good
Range 600 to 900Fair
Between 900 and 1200 Poor
Above 1200 Unacceptable

TDS Meaning

Total Dissolved Solids (TDS) represent the total concentration of dissolved substances that are dissolved in water.

The drinking water that we consume every day is flushed with hazardous chemicals from the different water treatment plants.

So, the natural minerals present in water are taken away. In such a situation, it is very important to use the proper filtration processes to remove the contaminants and make water safe for consumption.

What Is The Meaning Of TDS In Water?

All the TDS meter measures are basically the number of ions in the water. Most of the pesticides, hormone-disturbing substances, and drug residues are generally no ions.

 Water with a low ppm value is generally free from salts and minerals but can hide a large amount of non-ionic chemicals in itself.

So, the result of a TDS meter is not very meaningful with regard to the actual water quality. To check out, other analytical methods, or a water analysis by a reputable laboratory, can better result to find out about the real water quality.

TDS Full Form

The full form of TDS is Total Dissolved Solids. This term is used to represent the small amount of organic matter or the inorganic salts that are present in the solution in the water.

The major constituents as generally calcium, magnesium, sodium, and potassium cations and carbonate, hydrogen carbonate, chloride, sulfate, and nitrate anions, and the list goes on.


We have researched thoroughly and have come up with the conclusion that only if the TDS level of the water is up to 600, it is considered to be acceptable, else not. There are many water purifier/ purifiers that help in achieving the best TDS level that is suitable for drinking.

Attention, please! People with kidney problems should only consume water that has a TDS level in the range of 100ppm.

The little summary infers the fact that water with a low concentration of TDS is also not acceptable for the consumption of humans. The reason behind it is that it lacks the valuable minerals that are essential for the growth of the body.
