Drinking water TDS

TDS is a commonly heard term, but people are often confused about its meaning and significance. So, what exactly is TDS or Total Dissolved Solids? TDS means concentration of dissolved particles or solids in water. TDS comprises of inorganic salts such as calcium, magnesium, chlorides, sulfates, bicarbonates, etc, along with many more inorganic compounds that easily dissolve in water.

TDS impacts the salinity of water. If you feel that water at your home tastes salty and is not very palatable, your source of water is likely to have high level of TDS. The higher the TDS level, the difficult it becomes to consume water without purification. These dissolved solids may not be ideal for your health and must be filtered out before intake. Water purifiers with Reverse Osmosis (RO) technology is the best solution to treat water with high TDS. An RO water purifier doesn’t completely remove TDS, but reduces the level of TDS to make it palatable and consumable.

TDS levels may vary as per the source of your water. Usually, the TDS levels of Borewell are higher compared to those of Tank water or Municipal Water. TDS levels can range anywhere between 50-2000ppm. Not all levels of TDS in water are harmful for human consumption. Hence, it becomes critical to understand the significance of various levels of TDS.

Consumable Level:

WHO states that an acceptable range for the TDS level of water should be up to 300 parts per million (ppm) for it to be suitable for human consumption. Water with TDS level higher than 300 ppm may not be palatable as it can taste salty and may contain a high concentration of minerals like sodium, potassium and other salts in it. Any measurement reaching beyond 300ppm would ideally require an additional Reverse Osmosis Technology for purification of water. RO water purifiers use special membranes that hold back a considerable amount of these dissolved solids, to give only palatable, purified water.

Unsafe Level:

Water indicating a TDS level beyond 1000ppm may be unsafe for human consumption. As per WHO, TDS levels beyond 1200ppm are considered unacceptable. Water with high level of TDS, impacts the color, odour, and taste dramatically. It may be extremely unpalatable. In addition to the taste, water with high level of TDS may not be suitable owing to the excessive scaling caused by it in water pipes, heaters, boilers, and household appliances.

Solution:

RO water purification is the most effective technology in reducing the TDS of water and further enhancing the taste of water. There is a misconception that RO water purifiers completely remove the TDS. It is crucial to understand that RO water purifiers reduce the levels of TDS to bring it down to the acceptable levels, making it palatable to drink. Hence, if the TDS level of your source water is high (>300ppm), you must install a water purifier with RO technology.

Pureit RO water purifiers not only achieve the ideal TDS levels by removing excess TDS but also purify water to make it 100% safe as per USEPA guidelines. Pureit RO range of water purifiers remove harmful viruses, bacteria, pesticides, chemicals, and heavy metals to give you safe and pure drinking water. In addition to that Pureit water purifiers also add back essential minerals like Calcium and Magnesium to purified water.

While considering the health and wellbeing of your families, it is imperative to choose the right water purifier as per your need. Check out Pureit’s Advanced range of RO water purifiers.
