“…50 RO and other membrane technologies should be applied for treating pretreated leachate that will reduce membrane fouling and maintain a reasonable water flux to reduce the energy requirement. 51 For instance, an anoxic/aerobic granular activated carbon assisted membrane bioreactor integrated with nanofiltration followed by RO was found to produce dischargeable effluent with no intense membrane fouling. 52 RO should be the last step after another membrane treatment (e.g., ultrafiltration, nanofiltration) to reduce membrane fouling.…”

Advancement and Challenges in Municipal Landfill Leachate Treatment–The Path Forward!

Although landfill leachate is a small volumetric fraction compared to municipal wastewater, its complexity raises concerns for researchers and practitioners. Emerging and novel treatment technologies are being investigated to address landfill leachate treatment challenges. In the past decade, leachate research shifted from the removal of contaminants to the simultaneous recovery of resources and removal of contaminants. While resource recovery is appealing, it is also questionable due to the economic feasibility and post-environmental impact of applied resources. Various emerging contaminants may remain in recovered resources, making recovery a less preferred option. Because of the ineffectiveness of biological treatment of emerging contaminants, such as per- and polyfluoroalkyl substances, leachate cotreatment has been restricted in some wastewater treatment plants. Thus, in the wake of emerging contaminants and stringent regulations, it seems wiser to develop effective, integrated leachate treatments in lieu of widely practiced biological cotreatment. The solid waste industry needs viable, cost-efficient, and readily executable technologies to effectively handle the upcoming need. Thus, in this paper, academic and industry experts discuss the progress, challenges, and future of leachate treatment. This paper provides a forward-thinking evaluation of the past decade’s advancements and challenges in the field of landfill leachate treatment.

“…According to an estimate made by Samhaber and Nguyen (2014), the total cost of the industrial NF treatment process ranges from US$ 1 m −3 to US$ 6 m −3 . However, few studies mention the use of NF to treat landfill leachate (Amaral et al, 2016;Chaudhari and Murthy, 2010;De Almeida et al, 2019) and none of these studies have examined in detail the landfill leachate management costs. The costs for treatment of leachate vary from simpler processes such as co-treatment with sewage (about 18-27 € m −3 ) to more sophisticated technologies such as RO (15-40 € m −3 ) (De Almeida et al, 2019).…”

Nanofiltration applied to the landfill leachate treatment and preliminary cost estimation

The leachate treatment by nanofiltration (NF) process has received much attention over the last two decades. Previous studies focused on the investigation of the technical feasibility of NF. However, there are a limited number of works that examined leachate treatment costs. On the other hand, in a landfill management system, the economic component is an imperative factor for the decisions of all operations. Thereby, this work aimed to investigate the technical feasibility and economic parameters involved in a full-scale NF plant for the treatment of leachate previously treated by the physicochemical process. The average quality of the pre-treated leachate was 2258 ± 230 mg L−1 chemical oxygen demand (COD) and 821 ± 86 mg L−1 humic substances (HS). NF was performed using a bench-scale filtration module with commercial polymeric membranes SR100 and NP030. At the end of each filtration, a cleaning protocol was applied to recover the initial membrane permeability. The concentration of recalcitrant compounds, expressed as HS, was reduced to 84 ± 8 mg L−1 in the permeate, and COD complies with the wastewater discharge standards imposed by local legislation. The capital costs for a full-scale NF was estimated at MUS$ 0.772, and specific total cost, treated leachate per volume unit, has been estimated at US$ 8.26 m−3.

The reverse osmosis (RO) process has been increasingly applied to landfill leachate treatment. The published literature reports several studies that investigated the technical feasibility of RO. However, information about process costs is scarce. Also, companies that run leachate treatment plants do not provide actual costs. To fill this gap, this study aimed to evaluate the treatment costs of a full-scale RO for the treatment of landfill leachate located in Rio de Janeiro State, Brazil. A procedure was proposed to estimate the capital expenses (CAPEX), operational expenses (OPEX), and specific total treatment cost, the total cost per m3 of treated leachate, of the leachate treatment by membrane process, and the results obtained are discussed. The CAPEX for this full-scale RO was estimated at MUS$ 1.413, and OPEX ranged from US$ 0.132 to US$ 0.265 m−3 per year. The cost of leachate treatment has been estimated at US$ 8.58 m−3 considering the operation of the RO-unit for 20 years after landfill closure.
