Abstract

The roughing filters have effective size of the substrate grain which is greater than 2mm. This study aimed at the examination of the efficiency of horizontal roughing filter in nitrate, turbidity and chemical oxygen demand removal (COD), obtained in the fresh leachate from municipal solid waste landfill. This experimental study was conducted in 2014 in Karaj. 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, turbidity and COD. The sampling period lasted from March to August (2015). 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. The average removal efficiency of the turbidity in filtration rates of 0.5 m/h, 1 m/h and 1.5 m/h was equal to 72, 86 and 81 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 horizontal roughing filter was better than that obtained with COD and turbidity. © 2016, International Journal of Pharmacy and Technology.
