The study focuses on using sand and activated carbon filters for treating Al-Kasak refinery wastewater. The wastewater contains many contaminations, organic and chemicals materials. Many tests performed such as pH, E.C, T.S, COD, BOD, Phenole, Oil, NH3, After and before treatment with filter in order to determine effluent characteristics. The highest T.S removal efficiency with the sand filter was 93 % and 90 % for Oil. While the highest removal efficiency with activated carbon filter happened to Phenol which was 99 % and for COD and BOD was (81 - 90) % and (77 - 91) % continuously. The study shows that the cycle time of 9 hr gives the best removal efficiency for organic wastewater, especially for the high organic load. It was recommended to use a sand-Activated carbon filter to treat refinery wastewater because the effluents were within Limits of refinery wastewater casting and river casting.
