What is a Good TDS level? How to Calculate TDS Level in Drinking Water

Drinking bottled water is considered to be the safest option based on the fact that it doesn’t have any contaminants. Usually, the water safety level is measured by TDS, which stands for Total Concentration of Dissolved Substances.

Water is necessary for the proper functioning of the human body, and it is proved as the best choice which contains no fat, no cholesterol, and no calories. Beside all these facts, finding pure water habitat is not easy. Water gets contaminated with metals and which can easily make you sick.

Due to this, checking the water TDS level plays an important role in healthy living. If you are from a rural area where the water supply comes from a river or preserved water, then you have to be careful before drinking that water.

There are contaminants like pesticides, toxic elements, radiological hazards, and much more. You can use water TDS calculators and keep your family safe. The primary question which pops in mind is how the TDS calculator works and why you should buy them.

Well, we have covered some essential aspects which cover all your questions and important factors. Let’s have a look – 

Safest TDS Level of Water

The taste of water depends on the contamination amount. Water is safe when it is below 300mg/lt, and you will never suffer any problem. But, water is still safe if the contamination level is between 300-600mg/lt. It will be fair to drink water when it is below 900mg/lt. However, it is unsafe when the water TDS level exceeds 1200mg/lt. Due to this, you can say that below 900mg/lt is a good-to-go option.

You can find that most rivers and natural habits have a TDS level between 300 to 900mg/lt. If these sources are getting contaminated with any metal substance, then the quality keeps going down with time. In such cases, you can’t drink that water, and chances of getting sick are higher for sure. Using a water-purifier or any HEPA filter will be an effective option to keep yourself safe.

One more thing to notice is when the TDS level is below 300mg/lt, then it is also unacceptable.  It will be flat in taste, and it may have an insipid taste that you might not like at all. This quick description can give basic detail about what levels are acceptable and what are not. If you are wondering how to calculate the TDS level, then you have to buy a water TDS calculator.

Method to Calculate TDS Level

To calculate the TDS level of water, you can choose any of the reputed TDS water calculator devices. The market is flooded with numerous products, and choosing the best one is based on the design, accuracy, and type of filter it has. After buying a water TDS calculator, you have to follow the below-mentioned steps –

Using Digital TDS Meter

In this method, you have to take a temperature reading of water. Make sure that you don’t need deep digital TDS meter beyond 2 inches because the device is not waterproof.

  • Take water in any container and then dip thermometer inside. 
  • Press the power on button and take temperature readings now.
  • Now remove the protective cap of digital TDS meter and turn it on.
  • Dip digital TDS meter into the water and stir it inside. 
  • Make sure that you wait for ten seconds and press the hold button. 
  • Take it outside, take readings, and note it down.
  • In case you see, x10 then multiply the amount with ten.

This is one of the easy options, and it works perfectly every single time. Make sure that you read the manual offered by the manufacturers to learn more about the device you are using.

Use Filter Paper and Scale

The second method is a bit typical and might be hard to follow, but it is a lot more reliable option. You need a sample of water in the beaker, a sterilized beaker, a scale to measure, a pipette, a stirring stick, an evaporating dish, and Filter paper. After getting all these items, follow these steps – 

  • Start by weighing the evaporator dish.
  • Use a stirring stick to stir it properly.
  • Use a pipette to collect a 50ml sample.
  • Extract water from the sample and pour it on the filter.
  • Do it three times, and you will find sediments.
  • Let this paper dry off completely. 
  • Now weight evaporator again. 

After the whole process, you have the subtract after-experiment weight with the initial one. You will get numbers in milligram. Now, if you want to calculate the exact TDS level, then use this formula, which is TDS = [(A-B)*1000]/ml. 

Conclusion

These are two of the easiest methods which can help you calculate the TDS level at home. Both methods are effective, but using a digital TDS meter ensures a convenient choice, and anyone uses this option.
