English term or phrase: hard water
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 sentence(s):
  • 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

hårdt vand


Definition from Danmarks miljøundersøgelser; Miljøord:
Vand der indeholder Ca++, Mg++, Fe++ eventuelt HCO3--ioner. Er totalhårdheden i °dH mellem 10-20, betegnes vandet hårdt vand. Over 20 er meget hårdt vand. Hårdhedsgrader mellem 2-5 er blødt vand og mellem 5-10 mellemhårdt vand.

Example sentence(s):
  • I Østdanmark er der kalk i jorden, og det sure vand opløser kalken. Herved mister vandet sin sure egenskab; det bliver neutralt, men det har til gengæld fået et indhold af kalk. Som drikkevand kaldes dette vand for hårdt vand. Hårdt vand giver anledning til kedelsten ved kogning, og et øget forbrug af vaskemiddel ved tøjvask. - GEUS  
  • Hvis tilstedeværelse af hårdt vand fremmer dannelse af hårde stop i vandlåsene ved forbindelser med calcium og magnesium i skyllevandet, burde der forventes større problemer i områder med hårdt vand. Især i Østdanmark er der store områder med hårdt vand. - Miljøstyrelsen
