Water is an amazing solvent and you need to drink purified water in order to stay hydrated and this will ensure that your body functions properly. Regardless of how clean the drinking water would be, you cannot guarantee that about its purity and germ-free. It might contain various types of impurities that include pesticides, chemicals, heavy metals and many others. The water that is supplied to your home could also have microscopic pathogens, lead, and arsenic. It can also have a very high level of TDS (Total Dissolved Salts). TDS level of drinking water is something which is very closely associated with pure water. In this article, we will discuss the ideal TDS level of the water.
What is TDS?
Freshwater dissolves the minerals from the soil or ground where it flows. It is polluted by pesticides, wastage overflows from homes and, harmful toxins released from the factories. When this water is routed through metallic pipes it gets more solids which dissolve in it. Correspondingly groundwater goes through a few strata of soil and dissolves the minerals along the way. The sum of all these dissolved impurities in water is referred as TDS. It is expressed in mg per unit volume of the water (mg/l) which is also referred as ppm (parts per million).
Other than this, water also contains other pollutants like dirt, clay, mud. However, these impurities do not dissolve in water. The most common chemical constituents of TDS are calcium, phosphates, nitrates, sodium, potassium, fluoride, chloride, and iron.

Minimum TDS Level of Drinking Water
According to WHO water containing TDS level below 300 mg/l is taken as the excellent level of drinking water. The maximum concentration of TDS below 1000mg/l is usually acceptable for drinking. However, the acceptability for minimum TDS of drinking water may differ according to the circumstances.
According to the Bureau of Indian Standards, the ideal TDS concentration for drinking water is below 300mg/L. The maximum permissible limit of TDS in water is 600mg/L. Due to lack of good sources of pure water, most of the people have to drink water with TDS higher than the permissible limit.
|TDS level (mg/l)||Rating|
|Less than 300||Excellent|
It is recommended that people with kidney problem should drink pure water having TDS level below 100 mg/L. It will help them recover from their health situation. Water with very low concentration of TDS is also not acceptable for human consumption. It is because of its bitter taste and absence of valuable minerals which are essential for our body.
Here the question arises how to check TDS of water? TDS meters are easily available in the market. These TDS meters are not very expensive you can easily get at them at less than thousand rupees. You can also check the quality of water supply by collecting samples of water and get it tested by the certified labs. If you are planning to buy a brand new water purifier, you can get a free demo at your home. Some topwater purifier brands like Kent, Pureit etc. provide free demo service. Their technician will visit your home and will test the water quality. According to the quality and TDS level in water, they would suggest you best technology for purification of your supplied water. You can choose between RO, UV or UF technology-based water purifiers depending upon the quality of your water.

How to Filter water with high TDS?
There are many water purifiers available on the market. Controlling the TDS in water can only be done by using a water purifier that has RO filtration process in it. RO purification process is the best method of removing the contaminants from water and makes it pure and safe for drinking. Reverse osmosis is the effective process that can be used for purifying water with high TDS content. RO water purifier during the filtration process eradicates almost all kind of dissolved or suspended impurities from water.
Under this filtration process, the solvent passes through a porous membrane at high force thereby allowing you to have the purified water as the final output. During the purification process, the TDS level also gets curtailed down up to 10% the total TDS present in the raw water. RO can remove dissolved impurities like Lead, Mercury, Arsenic, Fluoride, Chlorine etc. from water and makes its 100% safe for consumption.
Water contains essential minerals also which are required for our body but, during the RO processing, all of the mineral gets washed away. This you might think to be a concern, but, thanks to Kent RO Systems, who have invented a new technology which helps in retaining those essential minerals. Kent RO water purifiers have inbuilt TDS controller in it, which allows you to retain the minerals in water thereby providing 100% safe and tasty drinking water.
As you know water is essential for our life, so its purity should not be neglected. Keeping this in mind, you need to ensure that you drink filtered water with right TDS level in it that would make you healthy and let you stay away from waterborne diseases. Always prefer to install an RO water purifier that can not only deliver pure water by removing all the impurities from it but can also assist in maintaining the proper tds level in it. Drink pure water and stay protected.
