28-7-2020· Water that has a high pH usually has a high hardness value and water that has a low pH usually has a low hardness value. This relationship is because minerals in water act as a buffer that reduces the amount of acid in the water. Factors that influence hardness levels include amounts of dissolved salts of calcium, magnesium and iron in the river.

Testing Water Hardness | Science project | Education.com

Water, the major building block of life, sometimes has additives for health reasons. Hard water is water that has a high amount of dissolved minerals, generally calcium carbonate or magnesium salts.This is not necessarily a bad thing—most water in our households has some degree of hardness.

What Causes Water Hardness – Effects and Solutions for ...

28-3-2020· Water with a high content of salts or minerals is called hard. The main causes of water hardness are dissolved calcium and magnesium (Ca2+ and Mg2+). Rainwater and distilled water are soft, as they include few ions. Water hardness is formed when water goes through chalk areas or over limestone and magnesium and calcium ions are dissolved into ...

Characteristics of boiler feedwater - Lenntech

Feed-water purity is a matter both of quantity of impurities and nature of impurities: some impurities such as hardness, iron and silica are of more concern, for example, than sodium salts. The purity requirements for any feed-water depend on how much feed water is used as well as what the particular boiler design (pressure, heat transfer rate, etc.) can tolerate.
