The term “water hardness” originally referred to the ability of water to precipitate soap and form soap scum. Soap is precipitated (or brought to the “surface”) by water containing high levels of calcium and magnesium. The “harder” the water the less soap will dissolve in the water. In current practice, total hardness is defined as Continue reading Hard Water

Hardness of Water - USGS

Oct 22, 2019 Measures of water hardness. Hardness is caused by compounds of calcium and magnesium, and by a variety of other metals. General guidelines for classification of waters are: 0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.

Water Hardness - an overview ScienceDirect Topics

Sidi Huang, Diane Miskelly, in Steamed Breads, 2016. 3.6.2 Hardness. Water hardness is due to the presence of calcium ions, and to a lesser extent, magnesium, iron, and manganese. Water of medium hardness (less than about 150 mg/kg as calcium carbonate) is desirable for steamed bread production as some of the mineral salts have a strengthening effect on gluten and stimulate yeast.

Water hardness chart for sizing water softener systems

WARNING: Beware of companies that tell you that each PPM of iron is equal to 4-5 Grains per gallon of hardness. The only time you see this is when an unscrupulous company is using a water softener as an iron filter. You should NEVER use a water softener as an iron filter when the iron is above .3PPM.

Water Hardness - an overview ScienceDirect Topics

Water hardness is handled a little differently from salinity in that in some countries the degree is the unit of measure. One German degree of hardness equals 10mg/liter (ppm) of calcium and magnesium oxide or 17.8ppm of CaCO 3 in the USA. This is not at all equivalent to salinity in that a relatively low salinity water rich in calcium and magnesium could have a relatively high degree of hardness.

water-hardness - Lenntech

The calcium and magnesium hardness is the concentration of calcium and magnesium ions expressed as equivalent of calcium carbonate. The molar mass of CaCO 3 , Ca 2+ and Mg 2+ are respectively 100,1 g/mol, 40,1 g/mol and 24,3 g/mol.

How to Convert PPM to Grains in Water Hardness Sciencing

Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon. For example, say you have a water hardness value of 180 ppm. Work out 180 ÷ 17.1 = 10.526.

What Should My Water Softener Hardness Be Set at ...

For example, let’s say your water hardness is 15 gpg, and you have 2 ppm of iron. The total hardness you need to set will be 25 on your softener to account for the iron levels. As I said before, though, get in touch with the manufacturer or check the manual where this information is often provided on how to adjust for iron levels.

The PH reading came back around 7.0 which was okay because it is a general test and 6.8 is close to 7.0. The iron test came back at 0 PPM which I know is wrong because iron is the reason I put the softener in and iron buildup was the reason I repaired it . My hardness came back at 0 grains which I also know is wrong based on my previous lab test.
