其他摘要：This study was conducted to investigate the removal of COD, BOD, turbidity and colour from leachate using vertical upflow f iltration technique. Limestone media with a density of 2554 kg/m 3 was crushed and graded in sizes of 4 8 mm, 8 12 mm and 12 18 mm. Trial runs were done before the main experiment at an interval of 24 h analysis. Leachate was between pH 7.94 to 8.12 before experiments but increased to pH 8.42 after the filtration process. Maximum headloss at steady flow rate 20mL/min was 0.5 cm. The optimum treatment was achieved with 4–8 mm, 8–12 mm & 12–18 mm media size in combination and removal efficiency was 22 to 81%, 22 to 75%, 32 to 86%, and 36 to 62% for BOD, COD, turbidity and colour, respectively. Vertical upflow roughing filter can be used for pre-treatment of l eachate before further treatment.
