Utilization of Processed Activated Carbon from Coconut Shell in Wastewater Treatment
- Activated carbons were prepared from a variety of carbonaceous raw materials such as coal, coconut shells, wood and lignite. The present research work is emphasized on the investigation of carbonization process of coconut shell. Firstly, physico-chemical properties of coconut shell and distillery wastewater were determined. The effects of carbonization temperature and time on the properties of prepared coconut shell activated carbon were investigated. The nature of prepared coconut shell activated carbon was analyzed by X-ray Diffraction (XRD) method. The characteristics of prepared coconut shell activated carbons such as moisture content, ash content, volatile matter content, bulk density and fixed carbon content were also determined. Then, the prepared coconut shell activated carbon and commercial activated carbon were utilized for treatment of wastewater from a distillery plant. The characteristics of distillery wastewater before and after treatment with prepared coconut shell activated carbon as well as commercial activated carbon were determined. The effects of important parameters such as temperature, initial pH, activated carbon (adsorbent) dose and contact time on the removal of total chemical oxygen demand (COD) in distillery wastewater were also investigated.
