Water is one of the most essential things in our lives. One can never imagine any form of life without water. We can stay away from various diseases by drinking water at frequent intervals.
However, drinking contaminated water can lead to several diseases and infections. Which is why we need water purifiers. They can remove harmful chemicals, bacteria and dissolved contaminants that are harmful to us. These purifiers can also effectively eliminate the chances of various waterborne diseases. Water that we drink usually comes from lakes, rivers, reservoirs and underground sources. These sources may have various TDS levels that are not usually safe for consumption.
What is mean by TDS Value?
Total Dissolved Solids (TDS) in water are some organic and inorganic materials, which include minerals and ions that are dissolved in a particular quantity in water. When water passes through stones, pipes or different surfaces, the particles are absorbed into the water. TDS in water can come from different sources such as minerals in chemicals used for treating water, runoff from the road salts and chemicals or fertilizers from the farms.
Why Do you Need to Measure Total Dissolved Solids?
Testing the water is a great way to check the quality of water that you receive and use for different purposes. Here are some reasons you need to measure TDS in water.
Taste- High levels of TDS in water affects the taste of your drinking water. Your water may taste bitter, salty or sulfuric depending on the type of dissolved solids present in water.
Maintenance of Filters- Water filtration systems are affected by a high level of TDS. Testing the water purifier systems regularly will ensure that the filters work properly
Cooking- Though high TDS doesn’t affect health, it can alter the taste of your food.
Health Purposes- Water with high TDS is completely safe to drink. However, some substances such as lead, or copper can lead to health hazards.
Cleaning- High TDS in water leaves ugly spots on your utensils. This type of water also fades the color of your clothes, lead to a buildup in your sinks, tubs, and faucets.
Why do you Need to Measure TDS?
The water that you receive exceeds the maximum level of TDS that needs to be present in water. Water that has a TDS level of more than 1000mg/L is unfit for consumption. A high level of TDS in water can lead to a number of health problems. The presence of potassium, sodium, chlorides increases the TDS level in the water. However, the presence of toxic ions such as lead, nitrate, cadmium, and arsenic present in water can lead to a number of serious health problems. This is especially important for children because they are much more sensitive to contaminants because their defense systems have not fully developed. The purer the water, one can be assured of good health. KENT provides one of the best water purifiers in India that come with a TDS controller to ensure that the water you drink is safe for consumption.
Drinking Water TDS
One of the important questions that many people have in their minds what is the acceptable TDS level in the water. To help you out, we are listing two tables which discuss the palatability quotient and acceptable TDS level.
TDS Level in parts per million(ppm)
Palatability Quotient Between 50-150
Excellent for drinking150-250
Poor Above 1200 Unacceptable
Is low TDS water harmful to Human Body?
TDS present in water is not a measure of any single contaminant and so is generally not regulated as a health issue by many government agencies. A high TDS level, however, can affect the taste and odor of water. The Environmental Protection Agency in the US has set the maximum recommended level of 500 milligrams per liter (mg/L).
The TDS level in water can be determined with the help of a TDS meter. A TDS test helps in determining the total amount of dissolved solids present in water. However, it doesn’t identify any individual compounds, the sources. As a result, it is essential to conduct some additional tests to determine the contaminants present in water.
How Much TDS in Water is Good For Health
The table mentioned below provides a permissible range of TDS in drinking water and reasons for why the TDS level mentioned in water is not acceptable for drinking:
TDS Level (Milligram/Litter) Remarks Less than 50Unacceptable as it lacks essential minerals50-150Acceptable for drinking. The TDS level is ideal for areas where the water polluted by sewage or industrial waste150-250Good. The water is ideal for people with cardiovascular disease250-350Good. The water is ideal for people with cardiovascular disease350-500Fairly acceptable500-900Less acceptable900-1200Least acceptable. Avoid drinking water which has a TDS level of 9001200-2000Water is not acceptable for drinking. Above 2000Unacceptable
According to the Bureau of Indian Standards (BIS), the upper limit of TDS level in water is 500 ppm. The TDS level recommended by WHO, however, is 300 ppm.
