Abstract
A commonly used remineralization process involves bringing CO2-acidified desalinated water in contact with a bed of limestone. Dissolution of limestone provides two essential ingredients to the water: bicarbonate alkalinity and calcium content. The kinetics of limestone dissolution with CO2 was studied as a function of inlet CO2 concentration, water flow velocity, and temperature. The experimental data conformed very well to the Yamauchi model. Optimal design of a hardening column is discussed.
