Read the amount of acid used to reach pH 4.5. The amount of alkalinity in the sample is calculated using the formula shown: Alkalinity, mg/L as CaCO3 = (mL H2SO4 x NH2SO4 x 50,000) mL of sample. In the equation above, 50,000 represents the equivalent weight of CaCO3 (50) multiplied by 1,000 mg. Fifty thousand is a constant used in the formula.
Prefabricated lime softening equipment is available for small systems. Also, there is an American Water Works Association Standard for quicklime and hydrated lime (ANSI/AWWA B202-93) that provides purchasers, manufacturers, and suppliers with the minimum requirements, including physical, chemical, packaging, shipping, and testing requirements.

The required conditions are maintained in reactor to obtain different grade of precipitated calcium carbonate. This slurry is further washed, filtered and dried to get fine powder of precipitated calcium carbonate.
Iron and Steel Quicklime -- both high calcium and dolomitic -- enjoys its most extensive use as a flux in purifying steel in the electric arc furnace (EAF) and basic oxygen furnace (BOF). Lime is particularly effective in removing phosphorus, sulfur, and silica, and, to a lesser extent, manganese.
Acetylene is a colorless, combustible gas with a distinctive odor. When acetylene is liquefied, compressed, heated, or mixed with air, it becomes highly explosive. As a result special precautions are required during its production and handling.
