An ion is an atom or molecule that has a positive or negative electrical charge. Calcium and magnesium ions are released into water as it dissolves rocks and minerals. These mineral ions in the water can cause scale buildup in plumbing, fixtures and appliances and affect their performance. In the hot water heater, heat removes some calcium carbonate and magnesium carbonate from the water, resulting in scale buildup, which can then slow the heating process and increase energy usage. Cleaning agents used with hard water are not able to completely remove dirt and grime. Cloths may become dingy and grey with time feel harsh and scratchy. Glass wear may become spotted as it dries. Films may leave on shower doors or curtains, walls and tubs, and hair washed in hard water may look dull and not feel clean. Hard water is considered a nuisance problem, but removing hardness ions is necessary for health problems.
A variety of techniques are marketed to manage hardness minerals. NRES focuses on the ion exchange softening process which remains the most commonly used technique for hard water in residential settings.
