They observed that the removal of ,calcium, with chemical precipitation (,adding carbonate,) was a 34–54%, but this value was increased to 98% when MICP bacteria were used. Another factor is the pH, which determines the ,acid,-based chemical equilibria, and thus defines the presence of ,carbonate, and the precipitation processes.
