Enter the water hardness value, in parts per million, into the calculator. Double-check the entry to ensure that it is accurate. 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...

The conductivity of the water for different blending ratios is determined and the change of conductivity with the blending ratio is used to determine a conversion factor for the conversion of conductivity values into hardness values.doi:WO2014006129 A1WEIDNER Peter...
Hardness is usually expressed in grains per gallon (or ppm) as calcium carbonate equivalent. Hydrogen Sulfide Sulfur, Rotten Egg Smell, Sulphur A corrosive and flammable gas often found dissolved in well water and often accompanied by iron and low pH values. The odor of water with as little ...
However, the abrasive grains are pushed into the surface of the material, due to the kinetic energy of particles, which could cause problems in further machining of the workpiece or a change in operating properties [16]. This effect of increasing hardness was also confirmed in an experiment ...
To check how much you can save rejecting bottled water, use our tap water calculator –you will be surprised by how cheap tap water is and how significant the potential savings are! But always remember to check for the quality and hardness regularly. ...
The ozonation process was installed with the UF membrane in one tank with a dosage of 2–5 ppm to oxidize the organic contaminants into smaller molecules. For further water treatment, granular AC was used to remove residual organic matters and ammonia. The removal efficiency for the surface ...
The swift advancement of sustainable energy technologies, coupled with the urgent need to address environmental challenges, has generated considerable inte
As the cost of equipment maintenance increases gradually, the hardness of water has become one of the criteria for judging production costs. Therefore, the softening of hard water has important practical significance. Various methods have been developed to address the problem of water hardenings, ...
Thanks to its water filter, the softener Iron Pro2 is able to remove hardness minerals, while also eradicating ferrous iron. This softener removes sediments, rust and sulfur up to 2ppm, with the exception of iron, calcium and magnesium. It is the perfect solution for any household with ...
