TL;DR: Today, the use of membrane technologies, more especially reverse osmosis (RO), either as a main step in a landfill leachate treatment chain or as single post-treatment step has shown to be an indispensable means of achieving purification.

TL;DR: In this paper, a combination of processes for the treatment of landfill leachates is presented, which consists in a chemical precipitation of the leachate using lime, followed by a standard filtration on a rotary drum vacuum pre-coat filter which separates the precipitated phase from the liquid phase before the final step of reverse osmosis.
72 citations
TL;DR: In this article, a pre-treatment with lime upstream ultra-filtration was envisaged, where the effluent considered is landfill leachate, and the results showed that the selectivity of membranes has an important influence on elimination of pollution from organic source.
24 citations
TL;DR: The results show that the lime treatment makes it possible to act efficiently on the inorganic fraction of leachates through a decarbonation mechanism which entails massive precipitation of the carbonates under the form of CaCO(3), and to eliminate by co-precipitation the high Molecular Weight organic macromolecules (>50,000 g.mol(-1)) such as humic acids.

TL;DR: The main conclusions arrived at from the overall assessment of the literature are that more work needs to be done on degradation kinetics and reactor modeling of the combined process, and also dynamics of the initial attack on primary contaminants and intermediate species generation.
2,046 citations
TL;DR: Major research efforts in the future could focus on the optimization of current technologies and use of combined physico-chemical and/or biological treatment of produced water in order to comply with reuse and discharge limits.

TL;DR: In this paper, the fundamental mechanisms of radical generation in different AOPs and select landfill leachate and biologically treated municipal wastewater as model wastewaters to discuss wastewater treatment with different Advanced Oxidation processes.
Abstract: Advanced oxidation processes (AOPs) were first proposed in the 1980s for drinking water treatment and later were widely studied for treatment of different wastewaters. During the AOP treatment of wastewater, hydroxyl radicals (OH·) or sulfate radicals (SO4
·−) are generated in sufficient quantity to remove refractory organic matters, traceable organic contaminants, or certain inorganic pollutants, or to increase wastewater biodegradability as a pre-treatment prior to an ensuing biological treatment. In this paper, we review the fundamental mechanisms of radical generation in different AOPs and select landfill leachate and biologically treated municipal wastewater as model wastewaters to discuss wastewater treatment with different AOPs. Generally, the treatment efficiencies rely heavily upon the selected AOP type, physical and chemical properties of target pollutants, and operating conditions. It would be noted that other mechanisms, besides hydroxyl radical or sulfate radical-based oxidation, may occur during the AOP treatment and contribute to the reduction of target pollutants. Particularly, we summarize recent advances in the AOP treatment of landfill leachate, as well as advanced oxidation of effluent organic matters (EfOM) in biologically treated secondary effluent (BTSE) for water reuse.

TL;DR: In this paper, a detailed review of previous researches on the inhibition of Anammox processes is presented, where the effect of inhibitory substances, such as substrates (ammonia and nitrite), organic matter (nontoxic organic matter and toxic organic matter), salts, heavy metals, phosphate and sulfide, are commonly present in the practical applications.

TL;DR: This review marginalizes various studies conducted so far about EPS nature-production-recovery, properties, environmental applications and moreover, critically examines future research needs and advanced application prospective of the EPS.
