dispensed (200 ppm). 7. To convert ppm Hardness to grains per gallon (gpg), multiply by 0.058. Record as gpg Hardness as CaCO3. gpg CaCO3 = ppm CaCO3 x 0.058 ANALYSIS OF HARDNESS IN SALT WATER When sea and estuarine waters containing very high levels of mineral salts are tested, the sample must be diluted before titration.

First, find out your water Total Hardness in GPG: Total Hardness (in ppm) divided 17.1 =Total Hardness in GPG. For example San Antonio = approx. 18 Grains. Then, Adjust for Iron: Add 4 grain Hardness per 1 ppm of Iron detected (round up). For example, San Antonio = 139.0 ppb = 0.139 ppm x 4 = .278 extra Grains, so round up to 1 Grain.

then multiplying by 50. Hardness of individual cations can be confusing because they can be reported as milliequivalents/L (meq/L), milligrams per liter (mg/L), parts per million (ppm), or grains per U.S. gallon (gpg). The mg/L and ppm are considered equal, and 1 grain per gallon is equal to 17.1 mg/L or ppm. To convert meq/L to ppm, multiply ...

Hardness: T o convert ppm to grains per gallon, divide by 17.12. The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases,

Water hardness is measured in "grains" per gallon, in milligrams of calcium (Ca) per liter, or parts per million, and German Degrees of Hardness (dH) [which we drop here as this is for fish tanks]. You can take a water sample to a water test lab to have its hardness measures. You can convert among water hardness measures.

Water hardness is unfortunately, expressed in several different units and it is often necessary to convert from one unit to another when making calculations. Most commonly used units include grains per gallon (gpg), parts per million (ppm), and milligrams per liter (mg/L).

ppm. Dividing these corrected totals by 17.1 converts the ppm as CaCO 3 values to grains per gallon (gpg) values. Since the ion exchange capacity is usually determined in kilograins (Kgr) per cubic foot, (1 Kgr = 1,000 grains), we can now determine the “throughput” capacity in gallons per cubic foot (gal/ft3) of resin. Simply divide the ...
