Effect of Microbial Induced Calcium Carbonate

2017-10-1  induced calcium carbonate precipitation (MICP) is a novel approach to improve the stability of the coal ash sediments by using natural, biological processes to cement the particles together. The tendency to capture some heavy metals remaining after coal combustion through co-precipitation is another advantage of using MICP treatment.
