What Is TDS Water?

TDS is a term that is often used, but many people are unsure of its meaning. What is TDS, or Total Dissolved Solids? TDS is the concentration of dissolved solids or particles in water. TDS includes inorganic salts like calcium, magnesium and sulfates as well as many other inorganic compounds that dissolve easily in water.

TDS can affect the water’s salinity. You may notice that your water tastes salty or is difficult to drink without purification. These dissolved solids can be harmful to your health, so they must be removed before you consume. Reverse Osmosis water purifiers (RO) are the best way to remove high TDS. An RO water purifier does not completely eliminate TDS but it reduces TDS levels to make the water more palatable and usable.

The source of your water may have different TDS levels. Borewell has a higher TDS level than Municipal Water or Tank water. TDS levels can vary from 50 to 2000ppm. TDS levels in water may not be harmful to human health. It is important to be able to distinguish between different levels of TDS.

What Is TDS In Water

TDS is the concentration of organic and inorganic substances dissolved in a certain volume of water. It refers to metals, minerals and ions. TDS of drinking waters are basically a measure of any substance that has not been dissolved in H2O. Total dissolved solids is formed when water comes in contact with soluble materials. TDS can be caused by a number of sources including municipal water treatment chemicals and natural water springs.

Consumable Level

WHO recommends that water TDS levels not exceed 300 parts per million (ppm), as this is considered safe for human consumption. It may be difficult to drink water with a TDS of more than 300ppm. This is because it may taste salty or contain high levels of minerals such as sodium, potassium, and other salts. A Reverse Osmosis Technology would be required for any measurement exceeding 300ppm. RO water purifiers have special membranes that retain a significant amount of these dissolved substances to provide purified water that is palatable.

Unsafe Level

TDS levels above 1000ppm could make drinking water unsafe. TDS levels above 1200ppm are unacceptable, according to WHO. TDS-high water can have a dramatic impact on color, odour and taste. It can make water taste bitter. Water with high levels of TDS might not be suitable due to excessive scaling in pipes, heaters and boilers.


RO water purification is the best technology to reduce the TDS and enhance the taste of water. It is often believed that RO water purifiers remove all TDS. It is important to know that RO water purifiers lower the TDS levels to make it more palatable. If your water source has a high TDS (>300ppm), then you should install an water filter with RO technology.

Pure Blue H2O RO water purifiers achieve ideal TDS levels by eliminating excess TDS. They also purify water to ensure it is safe according to USEPA guidelines. TDS is the full name for Total Dissolved solid. The Pure Blue H2O RO water purifiers eliminate harmful bacteria, pesticides, and chemicals to provide safe drinking water. Pure Blue H2O water purifiers can also return essential minerals such as Calcium and Magnesium, to purify water.

It is important to consider the health and well-being of your family members when choosing the water purifier that best suits your needs. Pure Blue H2O’s Advanced line of RO purifiers is available.
