Definition from
antoine.frostburg.edu:
Hard water is water contaminated with compounds of calcium and magnesium. Dissolved iron, manganese, and strontium compounds can also contribute to the "total hardness" of the water, which is usually expressed as ppm CaCO3. Water with a hardness over 80 ppm CaCO3 is often treated with water softeners, since hard water produces scale in hot water pipes and boilers and lowers the effectiveness of detergents.
Example sentences:
Some laundry detergents do not produce as many suds in hard water, these are likely to be soap-based products and do not work as well in hard-water as detergent based products. (water-treatment.org.uk)
Hard water also contributes to inefficient and costly operation of water-using appliances. Heated hard water forms a scale of calcium and magnesium minerals that can contribute to the inefficient operation or failure of water-using appliances. (Wilkes University)
Clothes washed in hard water often look dingy and feel harsh and scratchy. (sciLinks)

tvrdá voda
Definition from
www.infovek.sk:
Vodu, ktorá obsahuje väčšie množstvo rozpustených solí vápnika a horčíka, nazývame tvrdá voda.
Example sentences:
Podľa obsahu aniónov kyselín rozlišujeme prechodnú (uhličitanovú) a trvalú tvrdosť vody, ktorú spôsobujú najmä sírany. (www.infovek.sk)
Tvrdá voda zvyčajne chutí lepšie ako mäkká voda. Rozpustené látky v tvrdej vode pomáhajú produkovať tvrdé zuby a kosti, vďaka prítomnosti uhličitanu a fosforečnanu vápenatého. (www.infovek.sk)
Nežiaduci prejav tvrdej vody je; tvorba vodného kameňa vo varných nádobách, teplovodných trubkách, ohrievačoch vody a kotloch, vyššia spotreba pracích prostriedkov. (www.mkw.sk)

Enviromagazín:
Tvrdosť vody<br /> Tvrdosť vody spôsobujú rozpustené vápenaté a horečnaté soli. Celková tvrdosť vody sa udáva ako súčet koncentrácií (v mmol) vápnika a horčíka.
Example sentences:
Načo sa používajú zmäkčovače vody? Zmäkčovače vody sú spravidla sodné soli kyseliny fosforečnej, ktoré na svojich Na+ iónov vymenia za Ca2+ a Mg2+ ióny z vody. Tvrdá voda obsahuje tieto ióny vo forme uhličitanov, ktoré sa usadzujú v podobe vodného kameňa na súčiastkách práčky. (Učebnica chémie)
