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. Have you noticed a white residue on your clothing and cooking pots and wondered if you need water softening equipment? Here’s a look at how to test the hardness of water.

Water Hardness Limits It is universally accepted as prescribed by WHO, World Health Organization, that water below 60 PPM is considered soft and above that it is hard. For this test, you will need a small bottle with a fitted cover and water level mark. In its place, you can use the marked container in a water hardness testing kit. You will also need some dish soap and a measuring cup. Now that you know how to calculate water hardness in ppm, fill the bottle (to the mark) with water.

My neighbor said City water   Water hardness is measured in parts per million (ppm) or grains per U.S. gallon ( gpg), with one gpg being the same as 17.1ppm. Soft or softened water should  Mar 4, 2021 NOTE: The hardness values determined in the lab are expressed in parts per million (ppm) as calcium carbonate (CaCO3). Many water  Hardness is described as the total concentration of calcium and magnesium, expressed as ppm or grains/gallon of calcium carbonate (CaCO3). Softening is a pre-  Water Hardness.
