Why it is important to measure water TDS before buying waterpurifier?
What is TDS?
Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in water.
Dissolved content is a combination of organic matter like leaves and inorganic salts like calcium, magnesium, potassium , sodium,carbonates, nitrates, bicarbonates, chlorides and sulfates
TDS is measured reported in parts per million (ppm) or mg/liter.
Why Should We Check The Water TDS Level?
WHO recommends that water with a TDS level less than 300 mg/litre is safe for human consumption.
Bureau Of Indian Standard, recommended TDS level in water is 500 mg/litres.
However, various water purifier industry experts suggest to maintain a TDS level of 50-150 mg/litre.
Increased concentrations of dissolved solids can effect taste ,pH and softness of water.
Dissolved solids can produce hard water, which leaves salt deposits on fixtures, and on the insides of hot water pipes and boilers.
Soaps and detergents do not produce as much lather with hard water as with soft water.
Hard water causes water filters to wear out sooner, because of the amount of minerals in the water.
How To check Water TDS At Home?
Water TDS concentrations can be determined using a digital meter.
ADVISE : Test your water TDS source before buying a Water Purifier. Buy a TDS meter to check for same.
| TDS level | Required Water Purifier |
|---|---|
| TDS is less than 200 | UV, UF |
| TDS is greater than 200 | RO |
| TDS is greater than 2000 | Domestic Water Purifier cannot be used. Buy a water softening solution. |
