Controlled calcium carbonate precipitation can be used for various applications. Calcium carbonate precipitation occurs when dissolved calcium and carbonate are mixed at concentrations which exceed the solubility of calcium carbonate. With alternate injection of pulses of calcium chloride and sodium carbonate solutions in time through a porous...
