Abstract
This study investigates the use of calcined eggshells and microalgae for the removal of heavy metals from acid mine drainage AMD and the simultaneous enhancement of biomass productivity The experiment was conducted over a period of 6 days in a hybrid system containing calcined eggshells and the microalgae Chlorella vulgaris The results show that the biomass productivity increased to ~804 times its initial concentration of 0367 g/L as measured by an optical panel photobioreactor OPPBR and had a light transmittance of 95 at a depth of 305 mm On the other hand the simultaneous percent removal of Fe Cu Zn Mn As and Cd from the AMD effluent was found to be 9947 to 100 These results indicate that the hybrid system with calcined eggshells and microalgae was highly effective for heavy metal removal in the AMD
