While adding hydrochloric acid (HCl) to the solution of calcium carbonate (CaCO3) would be an effective way to reduce pH and prevent the CaCO3 from forming, it would not be very cost effective. Using HCl would not only add to the cost of water treatment in terms of money spent, but also in terms of complicating plant operation. As a result, a different solution was pursued.
