19 Min Read

To preserve excellent health, it is crucial to ensure water’s purity, 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 the water, the more impurities it contains.

Water purifiers with TDS controllers are designed to remove dissolved minerals from water, making it safe to drink. TDS controllers pass 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 when determining the taste and drinking water’s quality. The water may taste dull 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 remember that elevated TDS levels may indicate that the water contains potentially hazardous elements like arsenic, fluoride, or nitrates. To ensure that the water we drink is safe for our health, we must track TDS levels & take the appropriate measures.

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

The 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. However, water with a TDS level below 50 ppm can lack important minerals and be less 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 water level is 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 water level is believed to include the optimal ratio of minerals and salts, resulting in significant medical benefits and a tasty. Remembering that the appropriate TDS level can change based on personal needs and tastes is essential.

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, groundwater sources often have higher TDS levels than surface water sources.

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 impact TDS levels.

Tips for Maintaining Safe Drinking Water with Appropriate TDS Levels

Regular water testing and 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, choosing a water purifier that keeps the proper TDS level while getting rid of dangerous impurities is crucial.

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

It may also taste and smell foul, making consuming it unpleasant.

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 ensure that it has a balanced mineral content to stay healthy. As per 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 water source, location, and individual health conditions. It is crucial 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. You must use a water filtration system to remove TDS from the water.

A few different types of water filtration systems can be used to remove TDS. RO is the most effective method for removing TDS. Water is forced 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, you can do a few things to reduce it. One option is to install a water purifier in your home. This will remove TDS and other impurities from your water, providing clean, safe water.

Why should you measure TDS?

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

The higher the TDS level, the more impurities are in the water.

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 the taste of water salty or bitter and cause skin irritation. High TDS levels can lead to kidney problems and gastrointestinal disorders in extreme cases.

If your TDS levels are too high, there are several ways to reduce them, including reverse osmosis and distillation.


Cooking with water with a high total dissolved solids content can affect the taste of food. For instance, if chlorine is present at higher than recommended levels, it may leave an off-putting taste in cooked pasta or quinoa. The same applies to other natural minerals, such as iron and magnesium, in drinking water. When these build up and more is consumed, dishes like soup or stews can change the flavor. For this reason, it’s a good idea for cooks to filter their cooking water for the 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 unwanted materials and trapping them within tiny pores within the filter material. With these filters, you can eliminate any water impurities while 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.


A variety of issues can arise when cleaning that can be caused by high levels of total dissolved solids (TDS) in water. Problems like water spots on dishes, fading colors in clothes, and buildup in sinks are all common symptoms of 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 reduces the amount of TDS in the water, making it much easier to clean your home effectively and efficiently. Having cleaner water available for cleaning tasks means you no longer have to worry about dealing with frustrating issues related to high levels of total dissolved solids. Investing in a sound 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 essential aspects of filter maintenance. Not only does this ensure that the system appropriately filters out contaminants from your water source, but it can also alert you when maintenance is required for optimal performance. Testing for high levels of TDS in water indicates either a need for filter replacement or a clogged pathway that requires attention from qualified technicians. Additionally, filter changes should occur regularly depending on usage and the type of TDS removal media used, as this will affect its lifespan. Regular maintenance on your filtration system can extend its lifespan and provide safe and consistent products for 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 not-so-good immune systems are especially vulnerable to the effects of consuming contaminated water. Even if the water carries high amounts of TDS, it doesn’t mean it isn’t safe to drink: regularly testing for heavy metals is critical to maintaining clean water with a manageable TDS level.

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

Smell and taste

The taste and smell of tap water with a high concentration of TDS is an issue many people face daily. 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 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 for purifying tap water with a high concentration of TDS while preserving essential minerals that can improve taste and smell. Additionally, future issues caused by high concentrations of TDS will be significantly 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 your home’s water quality, consider testing the TDS in it. TDS measures 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 harm your health.

You can test the TDS level in your water at home in a few different ways. 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 use filter paper and a scale to estimate the TDS level.

By Using Digital Meter

A digital TDS meter is a simple and cost-effective option to determine the quality of your home’s water. 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:

1. Fill a clean cup with water that you want to test.

2. Turn on the digital TDS meter and insert it into the water.

3. Wait a few seconds for the meter to take a reading.

4. Remove the meter from the water and check the reading. The reading will tell you the amount of dissolved solids in the water.

5. Compare the reading to the TDS chart to determine the water quality. The chart will tell you whether the water is safe to drink.

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 using filter paper and a scale.

There are a few different ways to test the TDS level in your water, but one of the most accurate methods is to use 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 the water has passed through, weigh the filter paper on the scale. 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 water sample’s weight by the sample’s volume (in mL). This will give you the TDS concentration in ppm.


In conclusion, our overall health needs 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.

We are making sure that our drinking water is free of impurities and within the recommended TDS limits is essential. We can ensure that our drinking water is secure and nutritious using RO water softeners and routine testing with TDS meters. We may prioritize our health and ensure that we are consuming water of the proper quality by slightly tweaking our daily routine.
