hardness index of limestone

index hardness of limestone - uf1

The water hardness is expressed by an index, or total hardness, TH, in degrees, each degree determined by the following formula: 1 degree (°F : French unit) = 4 mg/liter of calcium or 2.43 mg/liter of magnesium or 10 mg of limestone. The waters are classified according to their TH (French TH) 0
