Abstract
Leachate is the waste water that discharged through the solid waste of the landfill. The leachates have a high composition of pollutants such as ammonium, chloride, sulphate, ferrum, cadmium, zinc, lead and also the high level of BOD and COD. Thus, the effective treatment procedure is being introduced to ensure the minimum effect of water pollution. This research discusses the results of removal of ammonium, COD, iron and zinc by using the combination of zeolite and activated carbon as the removal.The research is important to identify the suitable substances for pollutant removal of leachate. The main objective of this research is to obtain the level of effectiveness and the best combination for zeolite and activated carbon in the leachate treatment process. Meanwhile, this research also use to identify the size and the optimum quantity of both combination of these two substances in order to achieve the high level of effectiveness by referred to the producing adsorption isotherm of Freundlinch and Langmuir. Beside that, the result also showed the percentage of removal for COD, ammonium, ferum and zinc which is the combination of 0.3g zeolite and 0.1g activated carbon are the best combination to remove ammonia, COD and zinc with 60%, 57% and 55% of total percentage respectively. While the combination of 0.1g zeolite and 0.3g activated carbon is the best combination to remove iron with 70% of total percentage. The outcomes of this research are suitable for more commercial way of leachate treatment in the future because of it efficiency and the reduction of costs.
