The aim of this study was to investigate the heavy metal removal and biomass productivity in the Acid Mine Drainage (AMD) using eggshell and microalgae. The experiment was operated 6 days in the eggshell and microalgae hybrid system, and using eggshell powder and microalgae as Chlorella vulgaris. The obtained result indicated that the biomass productivity of 2.82 g/L/d from 1.12 g/L initial concentration in 6 days was reached with light transmittance of 97% at a 305 mm depth in the optical panel photobioreactor (OPPBR). The total removal efficiency of Fe, Cu, Zn, Mn and Cd was found to be 98.92%, 99.91%, 98.78%, 88.99% and 98.00% in the AMD using eggshell and Chlorella vulgaris hybrid system, respectively. Additionally, there were significant relationships between biomass and concentration of each heavy metal ($R^2$ = 0.8771, 0.8643, 0.8669, 0.9134 and 0.6277 for Fe, Cu, Zn, Mn and Cd). These results indicated that the eggshell and microalgae hybrid system was highly effective for heavy metal removal when compared to the conventional biological process in the AMD. Therefore, the eggshell and microalgae hybrid system was effective for heavy metal removal and biomass productivity and can be applied to treat AMD in treatment plant.
