The drinking water that we get today is flushed with hazardous chemicals from the different water treatment plants. As a result, the natural minerals present in water are taken away. In such a situation, it is essential to use the proper filtration processes to remove the contaminants and make water safe for consumption. The main contaminant present in water is total dissolved solids that are left in water after normal filtration process. Contaminants that are larger than 2 microns are termed as total dissolved solids. A fine filter generally removes particles that are 0.45 microns in size and originates from different sources. The remaining contaminants in water after the filtration process consist of charged atoms and ions. Moderate to high TDS in water not only changes the taste of water but also poses a lot of health hazards. One of the most effective ways to maintain the TDS level is by using the best RO water purifier in India. In this blog, we discuss in detail about the ways to remove excessive TDS present in water.
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. Presence of potassium, sodium, chlorides increase the TDS level in water. However, 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 defence systems have not fully developed. The purer the water, one can be assured of a good health. KENT provides best water purifiers in India that come with a TDS controller to ensure that the water you drink is completely safe for consumption.
Does TDS lead to Health Issues?
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 odour of water. The Environmental Protection Agency in the US has set the maximum recommended level of 500 milligrams per litre (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.
Ways to Reduce or Remove TDS in Water
1. Reverse Osmosis (R.O.)
Reverse Osmosis removes TDS by forcing the water, under pressure, through a synthetic membrane. The membrane contains microscopic pores which will allow only molecules smaller than 0.0001 microns to pass through. As the molecules of dissolved metals and salts are large compared to the water molecules, water squeezes through the membrane leaving the metals and salts behind.
The process involves boiling water to produce water vapour. The water vapor rises to a cool surface where it is condensed back into the liquid form. The dissolved salts are unable to vaporize and remain in the boiling solution.
3. Deionisation (DI)
In this process, water is passed through a positive and negative electrode. The ion selective membranes enable the positive ions to separate from water and move towards the negative electrode. The end result is de-ionized water with high purity. However, the water is first passed through a reverse osmosis unit first in order to remove the non-ionic organic contaminants.
Why Should you Keep a Check on the TDS Level?
There are a number of reasons why you need to check the TDS level in water. Some of the reasons are:
Taste and health
High TDS level alters the taste of water and make it salty, bitter, or metallic. High TDS levels also indicate the presence of toxic minerals which is hazardous for health.
High TDS makes water hard, leading to scale build up in pipes, dry hair, spots on utensils and also make the kitchen appliances ineffective. Checking the TDS level of water helps you avoid these problems beforehand.
Pools and Spas
Pools as well as spas need to monitor the TDS level in water constantly to prevent any maintenance problem.
