TDS stands for Total Dissolved Solids. TDS are the inorganic and organic matter present in the water that affects the taste and quality of water. These dissolved solids contain salts (like sodium, calcium, magnesium, potassium, etc.), metals (like lead and arsenic), minerals, and ions that are present in water.

TDS level refers to the amount of TDS content present in the water. The TDS level that is fit for drinking is specified by the Bureau of Indian Standards (BIS). According to BIS, the best TDS for drinking water is the value of up to 500 mg/liter. If the TDS level is below 500 mg/liter, then it is considered the best TDS for drinking water. However, if the value is higher than 500 mg/liter, then there is high TDS in water and the water is unfit for consumption. The unit of measurement for TDS is mg/liter which is also referred to as parts per million (ppm).

For high TDS in water, you will need a water purifier with RO technology to effectively filter out the dissolved solids.

Hence, before you buy a water purifier you must check the TDS content and choose the type of water purifier that’s ideal for your household. In that sense, you should know how to check TDS in the water at home so that you can check the TDS of RO water too.

What is the best TDS for drinking water?

The best TDS for drinking water as directed by WHO is as follows

<50-250ppm- Too low. Water with this level of TDS is devoid of essential minerals required and beneficial for our health.

300-500ppm- Good. This is the best TDS for drinking water.

500-900ppm- Fair. Water with this TDS level should be purified using an RO system before drinking.

900-1200ppm- Poor. Water with this TDS level must be purified compulsorily.

>1200ppm- Unacceptable. Water with this TDS level is harmful to drinking and also cannot be purified using the RO system designed for households.

In the next section, we will discuss how to check TDS in the water at home. For assistance, consultation, and installation of the best water purifiers for your home from a reliable water purifier service near me, contact the RO service center at +91-800-603-5444

How to check TDS in the water at home?

There are many ways to check TDS in the water at home. We will mention three common methods to check TDS in the water at home.

Method 1: Using Digital TDS meter

The easiest method to check TDS in the water at home is using a digital TDS meter. The meter helps you check the TDS in water in a few simple steps. You can also use the meter to check the TDS of RO water to see if the RO is functioning properly.

How to check TDS in the water at home using Digital TDS meter-

  1. Switch the meter on.
  2. There is a ‘TEMP’ button. When you click on it, the temperature will be displayed in the form of degree Celsius.
  3. To return to the TDS mode, click on the ‘TEMP’ button again.
  4. Open the protective cap of the meter.
  5. Now, put the meter in water. You will see a mark in the meter showing the maximum immersion level. Don’t immerse the meter in water, higher than the marked level.
  6. Once you immerse the meter in water, gently stir it.
  7. It will take around 10 seconds for the reading to stabilize. Once the reading has been stabilized, you can press the ‘HOLD’ button to pause the reading and check it properly after taking it out of the water.
  8. Some meters display an ‘x10’ symbol. If your meter displays that symbol that you have to multiply the TDS reading by 10.
  9. Once you’ve noted down the reading, shake off the extra water from the meter, and put the cap on.

Digital TDS meters are very easy to use. However, you should make sure that you don’t immerse them in the water beyond the maximum immersion line. Also, keep them away from direct sunlight. You can easily get digital TDS meters from any medial or retail stores.

Method 2: Using electrical conductivity meter

To check TDS in the water at home using an electrical conductivity meter, you will need an electrical conductivity meter, a clean sterilized glass beaker, and a water sample with a temperature around 250°C.

The reading from the electrical conductivity meter is shown in µS (micro Siemens). It shows the purity of water. The purest form of water has 0 µS.

How to check TDS in the water at home using electrical conductivity meter-

  1. Pour the water in the beaker and place the beaker on a flat surface.
  2. Switch the conductivity meter on.
  3. Insert the measuring lead from the meter into the water.
  4. Wait for the reading to stabilize and then note down the reading.
  5. The reading you get is shown in µS. To get the TDS level, you will have to use a formula.
  6. TDS (in mg/litre) = KE (Co-relation factor) X EC (Conductivity)
  7. EC is the reading that you got in the conductivity meter.

KE of water at 250°C is 0.67 approx.
Multiply your reading with 0.67 and you will get the TDS level.

Even though this method works, it is a bit longer than the method using digital TDS meters.

Method 3: Using filter paper and weighing scale

Using filter paper and weighing scale doesn’t require any TDS meter and you can easily measure the TDS level using items at home. For this method, you will need a filter paper, sterilized beaker, water sample, evaporating dish, sterile stirring stick, pipette large enough to collect a water sample of 50ml, and weighing scale.

How to check TDS in the water at home using filter paper and weighing scale

  1. Weigh the evaporating dish- Empty the evaporating dish and keep it free from any dust and particles. Weigh it and note the weight. Let’s mark this weight as A.
  2. Use a stirring stick to stir the water sample- Stir the water sample that you have taken and keep stirring vigorously to evenly distribute all the particles in the water.
  3. Collect 50 ml of a water sample using the pipette- Use the pipette to collect 50 ml of the water sample. Keep stirring the water even while collecting the sample. If you don’t stir continuously, the particles in the water will settle in the bottom of the beaker with sample water and this will not give an accurate result.
  4. Use filter paper to filter the water- Pour the water from the pipette to another beaker through a filter paper. Repeat the process about 3 times to ensure that all particles are collected in the filter paper.
  5. Transfer the particles from the filter paper to the evaporating dish- If there are particles in the filter paper, then transfer them to the evaporating dish and let them dry.
  6. Weigh the evaporating dish- Weigh the evaporating dish with the particles inside, after the particles have dried. Note down the weight. Let’s mark this weight as B.
  7. Measure TDS- Subtract the weight of the particles in the evaporating dish (B) with the weight of the evaporating dish when it was empty (A).
    Now multiply the result with 1000.
    The result is the TDS in mg/liter.

TDS = [(B-A)*1000]/ml

Checking TDS in the water at home using filter paper and weighing scale is a conventional method that doesn’t require any additional equipment.

You can also get your TDS in water checked by contacting the RO service center at +91-800-603-5444. Along with checking the TDS level, we also demonstrate how to check TDS in the water at home, and suggest the type of water purifier that’s ideal for your home.

You can use the methods mentioned in ‘how to check TDS in the water at home’ section to check the TDS of RO water. This will be helpful in determining whether or not your RO system is working properly.

Normally, TDS of RO waterfalls between 50mg/liter to 500mg/liter.

Using the RO system for purifying water at your home is recommended only if the TDS level of the tap water is more than 500mg/liter. If you use the RO system for water with less TDS level, then the RO technology will filter out even the necessary minerals from the water which is not an ideal solution.

Hence, to ensure that the TDS of RO waterfalls between 50 mg/liter to 500mg/liter, use the RO water purifier if the TDS level of your tap water is between 500mg/liter to 1200mg/liter.
