Heavy Metals Removal from Industrial Wastewater by Activated Carbon Prepared from waste material

Environmental Engineering

Activated carbon produced from coconut shell, Banana peel, Rice Husk and Egg shell was used as adsorbent to remove Cr, Cd, Fe 2+, Zn 2+ and Pb 2+ ions from industrial wastewater. The activated carbon produced artificially by waste material of various agricultural and vegetative. Batch adsorption experiment was conducted to examine the effects of adsorbent dosage, pH and stirring rate on adsorption of Cr, Cd, Fe 2+ , Zn 2+ and Pb 2+ from the wastewater. The obtained results showed that, the adsorption of the metal ions was adsorbent dosage and stirring rate dependent. The optimum adsorbent dosage and stirring rate were found to be at 0.2g to 1.0g, 200 to 350 rpm respectively. Removal efficiency showed the adsorbents capacity to treat the industrial waste water at different dosage.. Also it is noticeable that activated carbon of taken in study in which coconut shell and Egg shell shows the higher efficiency at low adsorbent dosages but in other adsorbent Banana shell and Rice Husk shows higer efficiency with higher dosage for removal performance in industrial wastewater to remove heavy metal from wastewater sample. The overall quality of the treated water is ideal for the various purposes such as for irrigation, discharge in to the canals. The re-origination of the various metals and adsorbent regeneration without any further techniques, also it will down the overall cost in the removal of any water/wastewater as compared to chemically treated The study also showed that activated carbon prepared from Banana peel, Rice Husk, coconut shell and Egg Shell can be efficiently used as low cost alternative for removal of Heavy metal ions
