Abstract
Treatment of Fresh Leachate From Municipal Solid Waste
This study aimed at the examination of the efficiency of roughing filter in nitrate and chemical oxygen demand removal (COD), obtained in the fresh leachate from municipal solid waste landfill. Sampling was done in 3 rates 0.5m/h, 1m/h and 1.5 m/h, including simultaneous sampling from input and output filtering, to determine the concentration of nitrate and COD. The average efficiency of COD removal in filtration rates of 0.5 m/h, 1 m/h and 1.5 m/h was equal to 84, 88 and 85 % respectively. The average removal efficiency of nitrate in filtration rates of 0.5 m/h, 1 m/h and 1.5 m/h was equal to 88, 88 and 85 % respectively. Output values of COD and nitrate were lower than the environmental organization standard (p < 0.05). Based on the results of this study, the nitrate removal with a roughing filter was better than that obtained with COD.
