WebMeasuring water hardness Water hardness is measured by the number of mineral deposits in your water (parts per million – ppm). A soft water area would have under 60ppm while a very hard water area would register more than 180ppm. WebThe last important method of removing the hardness of water is Clark’s method. It removes salts of magnesium and calcium by adding cold lime. It is performed using change in Ph. Ca (HCO3)2 + Ca (OH)2 → 2CaCO3 + 2H2O. Clark’s process is also known as cold lime softening. If we are elaborating the process of Clark’s process, it will be.
