In this research, an immobilized biofilm reactor was established for the simultaneous removal of calcium (Ca), fluoride (F), nickel (Ni), and nitrate (NO-N) by microbial induced calcium precipitation (MICP). The operating parameters of the reactor, hydraulic retention time (HRT: 4, 8, and 12 h), influent Ca concentration (36.0, 108. Read More
