Have you had second thoughts about the quality of water that you receive at your home? If yes, you should get a TDS meter to test the quality of water you are consuming every day. Based on the resulting TDS level of water, you can decide whether or not you need to install a water purifier with TDS controller. In this article, get to understand what TDS is and how to check the TDS level of water at home.
What Is TDS?
TDS stands for Total Dissolvable Solvents that are permissible in water. These include salts like calcium, magnesium, and potassium that impart nutritional value to water. The purest form of water isn’t ideal for consumption. As per the Bureau of Indian Standards, the permissible limits of TDS are as follows:
- 150 to 250– This is the healthiest level of TDS in water, especially for the cardiovascular health of a person.
- 250-350– Many cities in India use groundwater to support their daily water requirements. The groundwater has a relatively higher TDS level of 250-300. However, it is safe for consumption.
- As per the Bureau of Indian Standards, the TDS level that is deemed fit for consumption is up to 500. Anything above that is unfit and unhealthy for consumption.
Is TDS Harmful or Safe?
The broad classification of the TDS present in water can be done based on its effect on the human body i.e. beneficial and very harmful. The solvents in water include essential minerals like calcium, and potassium that are beneficial for health. However, owing to the excessive water contamination, there are other disease-causing solvents present in water like lead, arsenic, and mercury. These heavy metal impurities need to be filtered out using a water purifier. A higher level of TDS can cause a number of diseases and children are more susceptible to these impurities as they have a weaker immune system.
How Do You Know the Level of TDS in Your Water?
Measuring TDS level in water is an easy task. All you need is a TDS meter. It is a small handy device that measures the conductivity of the water and estimates the TDS. However, TDS meter does not measure the contaminants of the water. You can use a TDS meter at home without any assistance.
- Collect water in a clean glass or bowl.
- Turn on the power of the TDS meter and remove its cap.
- You will notice two electrodes at the end. You will have to immerse only these electrodes into the water. These electrodes will measure the conductivity of the water.
- Take precaution to not immerse the whole unit into the water as it can cause damage.
- You need to wait for a few seconds for the TDS reading to stabilize. The final reading is the TDS level of the water.
- Once you get the reading, you must remove the electrodes from water and rinse it with the RO purified water. This ensures that the electrodes don’t have any contamination on it.
- Don’t forget to dry the electrodes and place the cap on it.
How Can You Reduce the TDS Level of Water?
If the water you receive has an alarming level of TDS, you will need to take immediate steps to control it. You can eliminate the excess TDS by using an RO water purifier. In this process, the water is passed through a semipermeable membrane that allows only very small molecules (usually up to the size of 0.00001 microns) to pass through it. The TDS solvent molecules are large in size and get trapped in the membrane. Hence, you get clean drinking water.
Drinking water is essential for survival without which every living being will perish. More than 60 percent of your body is water and the daily requirement of water to keep your body functioning is more than the food requirement. Hence, what you put in your body can dictate the long-term health of your body. Clean drinking water is essential for maintaining the best of health. You must use an RO water purifier to purify water and keep yourself and your family safe.
