Abstract:

Ash of burnt natural coal and low grade activated carbon was used for the reduction of chemical oxygen demand (COD) from sewage wastewater. To carry out this study a batch system was used for contact time, adsorption doze and pH. The comparative study of ash (burnt natural coal) and low grade activated carbon shows that the absorption capacity of ash of burnt natural coal is lower than that of the low grade activated carbon, but its low commercial value makes it preferable as compared to the low grade activated carbon for the treatment of sewage for reduction of COD. The results show 69.34% and 97.39% removal of COD by ash and low grade activated carbon, respectively. Similar trend has been observed for treatment time, adsorbent dose and pH of solution. Ash shows quite effective adsorption capacity for COD reduction of the domestic wastewater, though its capacity is lower than that of commercial grade activated carbon. The low material cost makes ash an attractive option for the treatment of domestic wastewater.
