Research ArticleOpen accessIn the author namesPhysicochemical and Microbial Caracteristics Performency in Wastewater Treated Under Aerobic ReactorAsma Ben Rajeb, Hamadi Kallali, Neila Saidi et al.Problem statement: The current work study the efficiency of biological wastewater treatment by an aerobic reactor which could be used in small agglomerations. RBC reduced physicochemical and microbiological load of wastewater but values remain above Tunisian standard. Approach: Experiments were conducted on a sand filled PVC column fed with wastewater treated by Rotating Biological Contactor (RBC) at a pulsed rhythm … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,681 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEvolution of Microbial Biomasses C and N during the Composting of Municipal solid WastesOlfa Fourti, Naceur Jedidi, Abdennaceur HassenProblem statement: The aim of this study was mainly focused on the evolution of microbial biomasses C and N during the composting of municipal solid wastes. Approach: The carbon and the nitrogen of the microbial biomass (BC and BN) were studied using the fumigation-extraction method. Results: The dynamics of the BC/BN ratio, index of the chemical composition of the whole … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,704 accessesView PDF Cite

Research ArticleOpen accessIn the author namesBehaviour of Main Microbiological Parameters And of Enteric Microorganisms During the Composting of Municipal Solid Wastes and Sewage Sludge in A Semi-Industrial Composting PlantOlfa Fourti, Naceur Jedidi, Abdenaceur HassenThis study was focused on the microbiological aspects of composting and on the behaviour of main prevalent microbial communities (non-pathogenic and selected pathogenic bacteria) during the composting process of municipal solid wastes and sewage sludge in a semi-industrial composting plant. Results showed that the dehydrogenase activity and Biomass C / Biomass N ratio showed a noticeable increase in the two … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 7,313 accessesView PDF Cite
