“…As reported in Section 3, the combination of aerated biological treatments and physical-chemical ones is the most used. Indeed, as is visible in Table 3, the results obtained allow considering these practices as reliable for COD and NH4-N removal, with special emphasis on AOP technologies with biological ones, also suggested in previous years and considered reliable solutions [177][178][179]. However, all of them do not achieve concentrations low enough to release the wastewater to water bodies and further treatments must to be applied such as membrane filtration.…”

Abstract:Municipal solid waste final disposal represents an environmental burden worldwide since landfilling, or open dumping, is still the preferred solution for the end of life of solid discarded materials. This study aims to review the technological innovations applied for landfill leachate treatment, taking into consideration the experiences obtained during the past years and the solutions which have been implemented. The review showed that both biological and physiochemical treatments are not able to achieve the requested water quality level, according to the limits established by regulations, whether applied in a single treatment or multiple treatments. In order to respect sustainable release limits to guarantee environmental protection, the construction of depuration systems and combining biological and physiochemical treatment methods is considered of the utmost importance. The review looks at possible joint applications of different treatment techniques reviewed by other studies and considers the state of the art of current research. Combined technical solutions suggested within the 2016 peer-reviewed papers are presented and discussed as a sustainable way to effectively treat landfill leachate, giving particular attention to feasible solutions for developing countries.

“…Furthermore, nutrient imbalances such as high ammonium nitrogen, low phosphorus and biologically degradable carbon content frequently occur in landfill leachate and make it difficult to maintain proper biological treatment and decent effluent quality. Therefore, post-treatment of biological effluents is still necessary to further remove organic matter [4,5]. The aforementioned limitations of biological techniques in addition to restrictive environmental legislations and the need for cost-effective treatments have led to an increased interest in the use of (advanced) oxidation processes ((A)OPs) such as Fenton, photocatalysis, UV/H 2 O 2 and ozonation as a valuable addition to conventional treatment techniques [6][7][8][9][10][11][12][13].…”

“…Jordá et al [14] reported a treatment cost of 0.74 €/m 3 for a paracetamol-containing wastewater ($1 mM; 100 mg DOC/L) using a photo-Fenton system. Cassano et al [15] reported the operating costs for the combination of a sequential batch biofilter granular reactor (SBBGR) and a solar photo-Fenton (SphF) process for the treatment of municipal landfill leachate (COD i = 2.8-3.6 g/L; DOC i = 0.9-1.2 g/L; N-NH 4,i = 1.5-2.0 g/L). The operating costs were 3.26 €/m 3 (2.54 €/m 3 for SBBGR and 0.72 €/m 3 for SphF) and 4.13 €/m 3 (2.54 €/m 3 for SBBGR and 1.59 €/m 3 for SphF) for a final COD of 500 and 160 mg O 2 /L, respectively.…”
