THE EFFECT OF KALDNES BIO FILTER MEDIA PACKING VOLUME ON THE EFFICIENCY OF MUNICIPAL LANDFILL LEACHATE TREATMENT

Full text

The purpose of study was to determine the effect of Kaldnes filtration media packing volume on the efficiency of ammonium removal in SBRs fed with municipal landfill leachate. The leachate was obtained from municipal landfill operated for over 10 years, and was characterized by COD of 4125.6mg.L^-1, BOD5 – 490 mg.L^-1, total nitrogen – 750 mg.L^-1 and ammonia nitrogen 580 mg.L^-1. Increase of filtration media's packing volume, has reduced the rate of ammonia nitrogen removal calculated per activated sludge units, while rate of reaction calculated per reactor volume has been comparable, regardless of media volume, with COD removal efficiency at the level of 17% to 28% and ammonia nitrogen 43% to 47%.
