Prosopis Juliflora Carbon and Commercial Activated Carbon in the removal of COD from aqueous solution
The local domestic wastewater is analyzed for determining its major pollutants. The efficiency of Prosopis Juliflora Carbon (PJC) and commercial grade activated carbon (CAC) is determined to remove Chemical Oxygen Demand (COD) from the wastewater. For this purpose a system of standardized batch absorbers under steady state conditions is used to study the effect of these media. The influence of treatment contact time, adsorbent dose, initial COD concentration and agitation speed on the rate of percent removal COD is evaluated. As alternative to commercial Activated Carbon Prosopis Juliflora Carbon (PJC) blend has shown quite effective adsorbent capacity for COD removal from the domestic wastewater. Though its capacity is lower than that of commercial grade activated carbon, the low cost material makes it an attractive option for the treatment of domestic wastewater.
