Abstract

ZnO has been coated on granular activated carbon (ZnO:AC) by dip coating method. ZnO:AC was used as photocathalyst material on Banger river’s waste water treatment. ZnO:AC was made by solving 1 g of ZnO powders in 100 ml aquadest , and then stirred by magnetic stirrer for 30 minutes until produced white solution. The solution then was mixed with 10 g of activated carbon granular that have been cleaned. This mixture was precipitated for 30 minutes, and was dried in furnace at temperature of 100°C for 3 hours. Microstructure and atomic composition of ZnO:AC were analyzed by SEM and EDX. The Photocatalytic ability of ZnO for purification and reducing stink analyzed by testing TDS and BOD of Kali Banger waste water. The testing of TDS and BOD was done on Banger river’s water by varying the length of time of water treatment. The results of characterization of ZnO:AC by using SEM and EDX showed that the ZnO has been coated on the surface of activated carbon. The water treatment process using UV light and ZnO: AC can reduce TDS value better than the other treatment. The combination between ZnO:AC and UV light also reduced BOD value of Banger river's waste water.
