          • Example sentence(s)
            • Fortesia e ujit Fortesia e ujit percaktohet nga sasia e kalciumit dhe magnezit qe permban uji. Fortesia totale perbehet nga fortesi karbonati dhe e perher shme (kalkarje - gelqeror). Kur uji me fortesi karbonati ngrohet, perberesi i tij i larte i kalkarjes depozitohet. Kjo sjell nje konsumim te larte energjie deri edhe daljen nga funksioni te disa prej paisjeve shtepiake. Uje i forte do te thote qe nevojitet me shume detergjent per larje dhe proceset behen me te veshtira.

          • Additional fields of expertise
          • Definition(s)
            • 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. antoine.frostburg.edu
          • 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

            • Твърда вода
          • Additional fields of expertise
          • Definition(s)
            • Твърда вода е вода с високо съдържание на минерали, обикновено калциеви и магнезиеви (Mg2+) йони, и в някои случаи други разтворени елементи като бикарбонати и сулфати. Противоположното понятие е мека вода - вода с ниско минерално съдържание. Калцият във водата обикновено се намира или като калциев карбонат (CaCO3) или като калциев сулфат (CaSO4).

            • Ефективността на перилните препарати при употреба в твърда вода се понижава многократно, в резултат на получаването на неразтворими калциеви и магнезиеви соли на висшите мастни киселини. - Internetreklama by bibienne (X)
