What should be Minimum TDS Level for Drinking Water in India?


In order to preserve excellent health, it is crucial to ensure the purity of water, which is an essential resource for human survival.

The significance of TDS in drinking water, the minimal, acceptable, and optimal TDS level of drinking water in India, and methods to assure safe drinking water with the appropriate TDS level are all covered in this article.

What is TDS in Water Purifier?

TDS stands for total dissolved solids (which includes inorganic salts, minerals, and other organic and inorganic substances) in water.The higher the TDS level in water, the more impurities it contains.

Water purifiers with TDS controllers are designed to remove dissolved minerals from water, thereby making it safe to drink. TDS controllers work by passing water through a semipermeable membrane, which traps the dissolved minerals and impurities, while allowing the water to pass through.

The Importance of TDS in Drinking Water

TDS is an important factor to consider when determining the taste and drinking water’s overall quality. The water may taste dull and boring if levels are too low. On the other hand, if levels are too high, the taste may be salty, bitter, or even acidic.

While TDS is an important indicator, it’s important to keep in mind that elevated TDS levels may be an indication that the water contains potentially hazardous elements like arsenic, fluoride, or nitrates. To ensure that the water we drink is safe for our health, it is essential that we track TDS levels & take the appropriate measures.

What is the appropriate TDS level for safe consumption of drinking water?

The Bureau of Indian Standards (BIS) in India has set a normal TDS of ro water of 50 ppm. This guideline ensures that the water is safe to drink and free of impurities. Water with a TDS level below 50 ppm, however, can lack important minerals and not be as healthy.

What is the suggested minimum TDS level for drinking water?

Drinking water with TDS levels between 50 and 150 ppm is also acceptable since it contains essential minerals and salts for good health. This TDS level of water is considered appropriate for consumption and has a pleasant taste.

What should be the acceptable limits of TDS Level in Drinking Water?

The Best TDS for water ranges between 300 and 500 ppm, while the acceptable range for TDS in drinking water is 50 to 150 ppm.

This TDS level of water is believed to include the optimal ratio of minerals and salts, resulting in significant medical benefits and a tasty. It is essential to keep in mind that the appropriate TDS level can change based on personal needs and tastes.

Factors Affecting TDS Levels in Drinking Water

The source of the water, the practices used to treat it, and the storage conditions can all have an impact on the TDS levels in drinking water. Because of the potential presence of absorbed minerals and salts from the earth’s crust, sources of groundwater often have higher TDS levels than sources of surface water.

TDS levels can be greatly reduced by treatment techniques like reverse osmosis (RO), however these techniques can also remove necessary minerals.Moreover, changes in mineral content and evaporation due to temperature and sunlight exposure throughout preservation might have an impact on TDS levels.

Tips for Maintaining Safe Drinking Water with Appropriate TDS Levels

Regular water testing and the usage of the proper water purifiers and filters are essential for ensuring purified water.TDS levels can be reduced by water softeners like RO systems, but they can also eliminate essential minerals.

Consequently, it’s important to choose a water purifier that keeps the proper TDS level while getting rid of dangerous impurities.

Moreover, pollutants can be removed from water while preserving necessary minerals using filters like activated carbon filters.

It may also taste bad and smell bad, making it unpleasant to consume.

In addition, there is evidence that digestive issues, renal stones, and cardiovascular disease are all associated with high TDS levels in drinking water. This is due to the high mineral content, such as sodium, in high TDS water.

Is 30 TDS water is safe for drinking?

A TDS level of 30 ppm is regarded as incredibly low in minerals and salts and may not be appropriate for consumption because it may be lacking in crucial minerals needed for our body to function properly. While having low TDS levels in water may not always be bad, it’s crucial to make sure that it has a balanced mineral content so that we can stay healthy.According to the Bureau of Indian Standards, the TDS level in water should be between 50 and 500 ppm (BIS).

TDS levels and their corresponding recommended standards:

Level (ppm) Recommended Standard
Less than 50 Not recommended
50 – 150 Acceptable
150 – 250 Good
250 – 500 Fair
Greater than 500 Poor

Please note that these recommended standards may vary depending on various factors such as the source of the water, location, and individual health conditions. It is important to test the TDS levels of RO water and consult with a healthcare professional if you have any concerns about the quality of your drinking water.

How to Reduce or Remove TDS in Water?

It is a common misconception that TDS in water can be removed by boiling the water. While boiling water will remove some impurities, it will not remove TDS. In order to remove TDS from water, you will need to use a water filtration system.

There are a few different types of water filtration systems that can be used to remove TDS. Reverse osmosis is one of the most effective methods for removing TDS. This type of system forces water through a semipermeable membrane, which removes impurities, including TDS.

Another option for removing TDS from water is distillation. This process involves boiling water and collecting the resulting steam. The steam is then condensed back into water, leaving impurities behind.

If you are concerned about the level of TDS in your water, there are a few things you can do to reduce it. One option is to install a water filtration system in your home. This will remove TDS and other impurities from your water, providing you with clean, safe water to drink.

Why should you measure TDS?

The quality of water is very important to human health. One of the ways to measure water quality is by testing for Total Dissolved Solids (TDS). TDS is a measure of the combined content of all inorganic and organic matter in water.

In general, the higher the TDS level, the more impurities are in the water. These impurities can come from a variety of sources, including agricultural runoff, sewage treatment plants, and industrial facilities.

While a certain amount of TDS is necessary for the proper functioning of our bodies, too much TDS can have harmful contaminants. High levels of TDS can make taste of water salty or bitter, and can also cause skin irritation. In extreme cases, high TDS levels can lead to kidney problems and gastrointestinal disorders.

Because of the potential health risks associated with high TDS levels, it is important to regularly test your water for TDS. If you find that your TDS levels are too high, there are several ways to reduce them, including reverse osmosis and distillation.


Cooking with water that has a high total dissolved solids content can have an effect on the taste of food. For instance, if chlorine is present in higher than recommended levels, it may leave an off-putting taste in cooked pasta or quinoa. The same applies to other minerals that are found naturally in drinking water, such as iron and magnesium. When these build up and more is consumed, it can change the flavor of dishes like soup or stews. For this reason, it’s a good idea for cooks to filter their cooking water for best results.

Using activated carbon filters to remove chlorine from drinking water is especially effective for reducing chlorine concentrations in your cooking water supply. Carbon filtration technology works by oxidizing the unwanted materials and trapping them within tiny pores within the filter material. With these filters, you can get rid of any impurities found in water while still maintaining minerals essential to your health, such as calcium and magnesium. Learning more about this filtering process is a great way to optimize the quality of your cooking and ensure better tasting results.


There are a variety of issues that can arise when cleaning that can be caused by high levels of total dissolved solids (TDS) in water. Problems like water spots on dishes and fading colors in clothes, as well as buildup in sinks, are all common symptoms of having high TDS levels. Unless the issue is addressed, these problems will continue to occur.

Fortunately, there is a way to combat the effects of these high TDS levels – installing a water softener or other filtration system into your home’s plumbing system. This type of system works to reduce the amount of TDS present in the water, making it much easier to clean your home effectively and efficiently. By having cleaner water available for cleaning tasks, you no longer will have to worry about dealing with frustrating issues related to high levels of total dissolved solids. Investing in a good filtration system will provide long-term benefits for ensuring a thorough and effortless cleaning regime within the home.

Proper maintenance of filters

Routine testing for TDS is one of the most important aspects when it comes to filter maintenance. Not only does this ensure that the system is properly filtering out contaminants from your water source, but it also can alert you when maintenance is required for optimal performance. Testing for high levels of TDS in water indicates either need for filter replacement or a clogged pathway that requires attention from qualified technicians. Additionally, filter changes should occur regularly depending on usage and what type of TDS removal media is being used as this will affect its lifespan. Regular maintenance on your filtration system can extend its lifespan as well as providing safe and consistent products into your end end-user applications.

Health Hazards

Lead, copper, and other heavy metals can seriously harm your health when present in water. Consumption of water with high levels of these metals can cause brain damage, developmental problems, and nervous system damage, among other serious issues. Those with compromised immune systems are especially vulnerable to the affects of consuming contaminated water. Even if the water carries high amounts of TDS , it doesn’t mean that it isn’t safe to drink: regularly testing for heavy metals is key to maintaining clean water with a manageable TDS level.

A home reverse osmosis system or a distiller are both effective solutions for filtering out potentially hazardous levels of lead, copper and other heavy metals from your drinking water. Therefore, investing in one may be an important investment for those living in areas where heavy metal contamination is detected at higher than normal levels or aged homes that contain pipes which may leak lead into tapped drinking water sources. These systems are also helpful for detect potential contaminants like bacteria and toxins that could be present in the water supply.

Smell and taste

Taste and smell in relation to tap water that has a high concentration of TDS is an issue many people have to face on a daily basis. As TDS increases, the taste of water changes from sweet and enjoyable to unpleasant and bitter. This is not only an issue impacting the taste of drinking water, but also influencing its smell due to compounds like chlorine and iron often being present in water with high levels of TDS.

Fortunately, there are ways to remedy this problem such as installing a reverse osmosis system or using a ceramic water filter. These methods are incredibly effective when it comes to purifying tap water with a high concentration of TDS while still preserving essential minerals that can improve taste and smell. Additionally, future issues caused by high concentrations of TDS will be greatly reduced due to the presence of these systems helping trap impurities before they enter our drinking supply.

How to test the TDS level in water at home?

If you’re concerned about the quality of your home’s water, you may want to test the TDS in it. TDS is a measure of the dissolved minerals, salts, and other small particles in water. While some dissolved solids are necessary for the water to be considered potable, too much can make it taste bad or even be harmful to your health.

There are a few different ways that you can test the TDS level in your water at home. The most accurate way is to use a digital TDS meter, which you can purchase online or at a home improvement store. If you don’t have a TDS meter, you can also use filter paper and a scale to estimate the TDS level.

By Using Digital Meter

To determine the quality of your home’s water, a digital TDS meter is a simple and cost-effective option. TDS, or total dissolved solids, measures the amount of minerals, salts, and other materials in water, and many digital TDS meters are user-friendly and affordable for at-home use.

Here are the steps for using a digital TDS meter to test water quality:

Digital TDS meters are a quick and easy way to test water quality at home. They are relatively inexpensive and can be found at most hardware stores.

The process involves the use of filter paper and a scale.

There are a few different ways that you can test the TDS level in your water, but one of the most accurate methods is to use a filter paper and a scale. This method will give you a more accurate reading than using a TDS meter alone, and it’s a good way to double-check your results.

Here’s what you’ll need:

-A filter paper

-A digital scale

-Water sample

To begin, take your water sample and filter it through the filter paper. Once all of the water has passed through, weigh the filter paper on the scale. Make sure to write down the weight, as you’ll need it later.

Next, take the filter paper and place it in a container of distilled water. Weigh the container and filter paper again, and write down the new weight.

Now, subtract the weight of the container and filter paper from the weight of the filter paper and water sample. This will give you the weight of the water sample.

Finally, divide the weight of the water sample by the volume of the sample (in mL). This will give you the TDS concentration in ppm.


In conclusion, it is essential for our overall health to maintain the proper RO Water TDS levels in clean water. TDS in water is acceptable up to a certain point, however high TDS levels might be detrimental to your well-being.

Making sure that our drinking water is free of impurities and within the recommended TDS limits is important. We can make sure that our drinking water is secure and nutritious for use by using RO water softeners and routine testing with TDS metres. We may prioritise our health and make sure that we are consuming water of the proper quality by making slight tweaks to our daily routine.
