What is TDS in Water Purifier?

While it is a sad reality that the water that passes through our taps are flush with harmful germs, bacteria and several hazardous chemicals, it is also heartening to know that modern science has equipped us with the tools to deal with these dangers effectively.

Total dissolved salts (TDS) are the major contaminants present in water, after even normal filtration processes are completed. TDS are contaminants that are larger than two microns in size, whereas a fine filter successfully removes particles that are more than 0.45 microns in size.

A moderate to high level of Total dissolved solids (TDS) in drinking water changes the taste of the water, and can be severely harmful to one’s health. Thus, it becomes essential to remove TDS before you drink the water.

However, how to get rid of TDS or even measure TDS is hardly common knowledge. People usually trust water purifiers to get the job done, but might not know the right questions to ask to learn whether their purifier can get rid of the TDS content in water as well. The best water purifiers in India, which are available for no-cost EMIs on the Bajaj Finserv EMI Store, can get the job done.

Read on to learn more about how to ensure that your water purifier is not only getting rid of germs, bacteria and harmful chemicals; but also taking care of the TDS content in water.

How much TDS is too much TDS?

  • TDS levels in your water can be measured through a TDS meter that gauges the amount of TDS in water. Presence of chemicals like potassium, sodium, chloride increase the level of TDS in water.
  • A TDS level of more than 1000mg/L of water is generally considered unfit for consumption. A TDS level of 50mg/L to 150mg/L is considered acceptable for drinking, and is ideal for areas where the water is polluted by sewage or industrial waste.
  • A TDS level between 150mg/L to 350mg/L is considered good, and is actually ideal for people with cardiovascular diseases.
  • The Bureau of Indian Standards (BIS) has set the acceptable upper TDS limit in water at 500ppm. The World Health Organisation (WHO), however, recommends an upper TDS level of 300 ppm.

How do I remove TDS from water?

The TDS content in water can be removed through TDS controller in water purifier. These are available in water purifier with TDS technology.

There are multiple methods of water purification. The TDS filtration methods are listed below:

  1. Reverse Osmosis (RO):

Reverse Osmosis is the process of filtering water by passing it through a semipermeable membrane. The best water purifiers in India are equipped with this technology which filters molecules that are smaller than 0.0001 microns to pass through. This not only eradicates bacteria, germs and other harmful chemicals; but also gets rid of TDS while allowing the water to pass through.

  1. Distillation:

The process of distillation is quite elaborate wherein the water is boiled and changes form to become water vapour, which is then collected upon a cool surface and converted back to water in the liquid form. Since the salts that were originally present are unable to vapourise, they remain in the container with the boiling solution.

  1. Deionization:

For deionization to work, the water first has to be passed through a semipermeable membrane such as the ones present in RO water purifiers, in order to remove the non-ionic organic contaminants. Then, the water is passed through a positive and negative electrode. The ion selective membranes enable the positive ions to separate from water and move to the negative electrode. The resultant solution is deionized water, which has a high level of purity.

TDS is often forgotten while customers are in the market looking for the best water purifier. However, TDS is a very big concern especially in areas situated near industrial parks or locations. The next time you set out to buy the best water purifier in India to ensure that the health of you and your family is taken care of, don’t forget to ask whether it has TDS technology or not.
