  Waste material from urban areas is a major environmental concern and landfill application is a frequent method for waste disposal. The leachate from landfills can, however, negatively affect the surrounding environment. A bioreactor cascade containing submerged biofilms was used to treat newly formed (< 1 year old) leachates of the Jbel Chekir landfill located southwest of Tunis, Tunisia. A preliminary analysis indicated a highly biodegradable portion of the leachate substances (BOD5/ COD = 0.4). The treatment system and performance was investigated at different organic loading rates. Results obtained during this study indicated a significant reduction in organic matter between 60 to 90% of Total Organic Carbon. The main bacterial genera responsible for removal of organic carbon in the leachate consisted of the genera Bacillus, Actinomyces, Pseudomonas and Burkholderia. The bacteri.. Read More»
