- OPERATIONAL PERFORMANCE OF VERTICAL UPFLOW ROUGHING FILTER FOR PRE-TREATMENT OF LEACHATE USING LIMESTONE FILTER MEDIA Augustine Chioma Affam Mohd. Nordin Adlan Ingeniería leachate Limestone landf ill vertical upflow roughing Filter 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. 2013 artículo científico 1982-3932 https://www.redalyc.org/articulo.oa?id=283227995012 en http://www.redalyc.org/revista.oa?id=2832 Journal of Urban and Environmental Engineering application/pdf Universidade Federal da Paraíba Journal of Urban and Environmental Engineering (Brasil) Num.1 Vol.7
