Biosorption of Lead (II), Copper (II) and Cadmium (II) in Singe-and Multi-metal Systems by Aerobic Granule Sludge by Fixed-Bed Column and Batch Sorption
Heavy metals are present in nature and industrial wastewater. Due to their mobility in natural water ecosystems and toxicity, the presence of heavy metals in surface water and ground water has become a major inorganic contamination problem. Discharge and treatment of industrial wastewater containing...
