Hardness of Water - USGS
2019/10/22· Water systems using groundwater as a source are concerned with water hardness, since as water moves through soil and rock it dissolves small amounts of naturally-occurring minerals and carries them into the groundwater supply.Water is a great solvent for calcium and magnesium, so if the minerals are present in the soil around a water-supply well, hard water may be delivered to homes.
Why calcium chloride? - Bijlsma Group
Superior by nature Calcium chloride (CaCl2) aggressively absorbs moisture from the air: It can attract several times its own weight in water, dissolving into a liquid brine if the air is humid enough and the temperature is high enough. The water is trapped in a merane-protected chaer, which prevents captured water from spilling or reevaporating […]
