  Calcium Carbonate Dissolution Rate in Limestone Contactors (EPA/600/R-95/068) July 1995

Limestone contactors have been shown to be an effective and economical water treatment device for reducing the tendency of water to dissolve corrosion by-products, such as lead, copper, and zinc, from surfaces in piping systems. Models used to design limestone contactors must predict the effect of a number of factors on the rate of carbonate mineral dissolution from the stone. This report describes the results of a study to determine the effect of limestone composition and water temperature on the carbonate mineral dissolution rate.
