What are Total Dissolved Solids (TDS) and How to Reduce Them?

What are Total Dissolved Solids (TDS) & How to Reduce Them?

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 the water after the 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.TDS level in the water

Why do you Need to Measure TDS?

TDS Meter – To measure TDS level of water. 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 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 defence systems have not fully developed. The purer the water, one can be assured of a good health. RO Water Plants provides best water purifiers in India that come with a TDS controller to ensure that the water you drink is completely safe for consumption.

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.

  1. Distillation

The process involves boiling water to produce water vapour. The water vapour 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.

  1. 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.

So, which Water Purifier is best?

One of the important factors that you need to consider when looking for a water purifier is the TDS level. Depending on the TDS level, you need to decide whether you need an RO, UF or UV water purifier. To make your work easy, here’s a table that will help you understand which water purifier is ideal for a particular TDS level.

Areas that receive water with a very high TDS level are recommended to use water purifiers that use a combination of RO+UV/UF with TDS Controller. The combination of various water purification technologies removes chemical, dissolved as well as physical impurities from water to make it suitable for consumption 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 the water. Some of the reasons are:

Taste and health

High TDS level alters the taste of water and makes it salty, bitter, or metallic. High TDS levels also indicate the presence of toxic minerals which is hazardous for health.

Hardness

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.
