Remineralization and Stabilization of Desalinated Water

This is due to the fact that 1) the dissolution or precipitation potential of the water with respect to calcium carbonate is often used as the key indicator to the stability of water; and 2) the alkalinity, calcium content and pH are the three major contributing factors in determining dissolution or precipitation potential of the water.
