GHI researches the hard facts about water softening and investigates if you need a water softener. Despite over 60% of homes being supplied with hard water only about 3% of households have a water softener fitted. They are quite expensive but worth the investment as softened water Hard water creates scaling on the cooling towers, boilers, and the other industrial equipment in the industry. So Water hardness should be monitored to escape from the costly breakdowns. Hardness can be removed by adding chemicals or by great scale softening with zeolite resins. Water softening systems. Hardness in water is caused by certain salts. The main hardness causing ions are Calcium (Ca2+), Magnesium (Mg2+) and Bicarbonate (HCO3 Softening units offer a water purification solution for hard water and lime scale removal. Hard water frequently becomes softer after it has been boiled for some time. The property of being softened by boiling which temporarily hard water possesses is not of much domestic use, for water is, as a rule, either not raised to a sufficiently high temperature or not kept at it for a long enough time. Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes and fittings. Water softening is usually achieved using Definition of "hard water": Hard water is generally taken to mean water containing minerals over 121 mc (micrograms) per liter of water, or over 7 grains of hardness per gallon. Hard water contains high levels of positively-charged ions or "Cations" of calcium, magnesium, and possibly other minerals.
