“…removal from 25 to 92 %. In another study, Tsilogeorgis et al (2008) concluded that ultrafiltration membrane-SBR was able to remove TN removal (88 % maximum) over 4 months monitoring. However, COD removal varied (40-60 %) due to high SRT.…”

“…The relatively high effluent concentrations of COD can be attributed to the presence of non-biodegradable compounds in the leachate. Operation with no sludge wasting is another factor that can contribute to low COD removal, whereby only 50% COD removal was achieved when treating old landfill leachate using an MBR at infinite SRT (Tsilogeorgis et al, 2008). Overall average removal efficiencies for various indicators (VSS: 95%; BOD 5 : 99.5%; COD: 70%; TN: 95%; NH3-N: 96%) were higher or within the range reported in the literature (Table 5) …”

“…An MBR can be considered as a conventional activated sludge system with efficient membrane filtration that holds small pore sizes of less than 0.1 mm (Santos and Judd, 2010). In the context of leachate management using the MBR technology, more efforts have targeted low-strength leachate (chemical oxygen demand [COD]: 1970[COD]: -2430[COD]: , 1391, and 1200-1600 mg L -1 ; Laitinen et al, 2006;Tsilogeorgis et al, 2008;Zhang et al, 2013) with fewer attempts at moderate to high strength leachate (COD: 4113-9257, 10,435-31,318, and 16,360 mg L -1 ;Xiu-Fen et al, 2011;Bai et al, 2011;Campagna et al, 2013). In general, considerably high biochemical oxygen demand (BOD) removals (90-99%) were attained with the MBR technology irrespective of experimental conditions and leachate maturity.…”

The management of landfill leachate is challenging, with relatively limited work targeting high-strength leachate. In this study, the performance of the membrane bioreactor (MBR) and sequencing batch reactor (SBR) technologies are compared in treating high-strength landfill leachate. The MBR exhibited a superior performance with removal efficiencies exceeding 95% for BOD5, TN, and NH 3 and an improvement on SBR efficiencies ranging between 21 and 34%. The coupled experimental results contribute in filling a gap toward improving the management of high-strength landfill leachate and providing comparative guidelines or selection criteria and limitations for MBR and SBR applications.Implications: While the sequencing batch reactor (SBR) technology offers some flexibility in terms of cycle time and sequence, its performance is constrained when considering landfill leachate associated with significant variations in quality and quantity. Combining membrane separation and biodegradation processes or the membrane bioreactor (MBR) technology improved removal efficiencies significantly. In the context of leachate management using the MBR technology, more efforts have targeted low-strength leachate with limited attempts at moderate to high strength leachate. In this study, the SBR and MBR technologies were tested under different operating conditions to compare and evaluate their feasibility for the management of high-strength leachate from a full-scale operating landfill. Such a comparison has not been reported for high-strength leachate.

“…Note however that excessively high SRTs might negatively affect the performance of MBR systems. It has been reportedly shown that COD removal decrease when increasing the SRT to 50 days (Hasar et al 2009b); further, low COD and phosphate removals were reported when operating at infinite SRT (Tsilogeorgis et al 2008). This might be due to the accumulation of inert matter in the MBR resulting in lower specific biomass activity (Pollice et al 2008a, b;).…”

Controlled landfilling remains a commonly applied method for municipal solid waste disposal with leachate generation being an inevitable consequence of the decomposition of the waste and the percolation of water through decomposing waste. The membrane bioreactor (MBR) technology has evolved into an effective process in treating such high strength wastewater streams because of its ability to retain high biomass concentration through membrane separation. This paper presents a critical review of the application of the MBR technology for the treatment of leachate and evaluates its performance in this context while highlighting factors affecting MBR operation. The paper concludes with outlining existing gaps and future research needs to improve the understanding and performance of the MBR technology for leachate treatment.
