ABSTRACT:
A process of removing carbonates from a wall of a water collection and treatment system injects carbon dioxide into "aggressive" water obtained prior to the end of the water treatment process to form aqueous carbonic acid solution which is pumped into the well to react with the carbonate deposits to form bicarbonate solutions which are pumped from the well. A preferred embodiment forms the acid solution with the product of a reverse osmosis desalinization water treatment step. Another embodiment forms the solution with the product of a softening step.
