The use of a submerged membrane batch reactor (S.M.B.R) for co-treatment of landfill leachates and domestic wastewater

Membrane bioreactor technology for leachate treatment at solid waste landfills

“…heavy metals) and overloading (i.e. high COD, TN and BOD; Ç eçen and Aktas 2004; Cosenza et al 2013a), several studies demonstrated that MBR systems were attractive options in areas that required the co-treatment of leachate and sewage because this would eliminate the burden of building new leachate treatment plants in addition to the existing sewage treatment plants, if any (Bodzek et al 2006;Bohdziewicz et al 2008;Hasar et al 2009a;Puszczało et al 2010;Litas et al 2012). Equally important, landfill leachate tend to have a stronger biochemical load but less volume than domestic treatment plants and their combination dilutes the leachate but care must be exercised to avoid potential chock loads at the plant if dilution is not ensured.…”

Optimization of COD, apparent color, and turbidity reductions of landfill leachate by Fenton reagent

“…Although biological treatments are the most common and cost-effective methods of waste water treatment, it should be considered that high amount of chemical oxygen demand (COD), biochemical oxygen demand (BOD 5 ), and low biodegradability (in terms of BOD 5 / COD ratio) in leachate characterization makes it as a refractory pollutant and classifies it as a resistant wastewater for any treatment (include biological treatment methods). In this case, to achieve better yield in order to enhance the leachate biodegradability, many researchers have worked on various treatment methods [4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”
