After 2-3 seconds, the display will light up and read “0.0” so you can start using the meter. You can buy a water hardness meter online or from hardware stores. 2021-03-26 · NOTE: If your water supply contains iron, compensate for it by adding to the water hardness number. For example, assume your water is 20 gpg hard and contains 2 ppm iron. Add 5 to the hardness number for each 1 ppm or iron. Correspondingly, what does the hardness number on a water softener mean?

Ppm water hardness

The following classifications are used to measure hardness in water: soft 0 - 17.1 parts per million (ppm); slightly hard 17.1 – 60 ppm; moderately hard 60 - 120 ppm; hard 120 - 180 ppm; and very hard 180 or more ppm. After filtration, the water we get is soft water. Permanent Hardness of Water: When the soluble salts of magnesium and calcium are present in the form of chlorides and sulphides in water, we call it permanent hardness because this hardness cannot be removed by boiling. We can remove this hardness by treating the water with washing soda.

Less expensive home tests also are available from local hardware or home supply stores. The following classifications are used to measure hardness in water: soft 0 - 17.1 parts per million (ppm); slightly hard 17.1 – 60 ppm; moderately hard 60 - 120 ppm; hard 120 - 180 ppm; and very hard 180 or more ppm.

As expected, you will get a smaller value— this is the water’s permanent hardness. Here is an example. Let’s say before boiling, the water’s total hardness was 50 ppm CaCO 3. Hardness is usually expressed in grains per gallon (or ppm) as calcium carbonate equivalent.
