“…Reverse osmosis (RO) seems to be one of the most promising and efficient methods among existent processes for landfill leachate treatment used as the downstream stage of integrated treatment or integral treatment (Yao, 2013). Several studies have been using RO in the landfill leachate treatment (Cingolani et al, 2018;Di Maria et al, 2018;Dolar et al, 2016;Schiopu et al, 2012;Talalaj et al, 2019). In the early 2010s, Šír et al (2012) reported that RO-plants were installed in more than one hundred landfill sites in northern Europe, North America, and the Far East.…”

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.

“…This is due to the ability to retain contaminants dissolved in leachate with high efficiency. Cingolani et al (2018) reported that RO can remove pollutants from leachate with an efficiency up to >99%. For this reason, it is preferred over other technological options.…”

“…LL is one of the most difficult wastewaters (WW) to treat because of its varied composition, particularly its high organic and total ammonia nitrogen (TAN) load [1,3]. Reverse osmosis (RO) is widely used as one of the most advanced LL treatment approaches [4], but several factors can affect its efficiency.…”

Reverse osmosis is widely used as one of the most effective and advanced technologies for the treatment of leachate from landfill sites. Unfortunately, high leachate contamination—above all, ammonia nitrogen—affects membrane selectivity and is reflected in permeate quality. Furthermore, iron contained in leachate can facilitate chelates forming, which reduces the membrane anti-fouling capacity. The addition of a pre-treatment step could alleviate the adverse impact of the pollutants. As such, we investigated pollutant removal by phycoremediation. Initial ecotoxicity tests of three algal strains (Scenedesmus obliquus (S. obliquus), Desmodesmus subspicatus (D. subspicatus), and Chlorella vulgaris (C. vulgaris)) identified D. subspicatus as the strain most tolerant to leachate toxicity. Subsequently, D. subspicatus was cultivated in six landfill leachates of different origin and, after the cultivation, removal rates were determined for ammonia nitrogen and iron. Furthermore, the impact of input leachate parameters on remediation efficiency was also investigated. By phycoremediation, the reduction of up to 100% in iron and 83% in ammonia nitrogen load was achieved, which demonstrates the high potential of microalgae to mitigate environmental risks and reduce membrane foulant content.

“…Countercurrent cascades are deployed for a range of industrially relevant separation processes [1], including cooling crystallization cascades [2,3,4,5], evaporative crystallization cascades [6,7,8,9], organic solvent nanoltration cascades [10,11], and reverse osmosis cascades [12,13,14,15].…”

A three-pass reverse osmosis process is employed in a seawater desalination plant in Saudi Arabia [12], combining one pass of a high pressure membrane with a two-pass countercurrent conguration using a low pressure membrane.…”

This work covers general multistage binary separations with application examples in cooling crystallization, evaporative crystallization and organic solvent nanoltration. Deterministic global optimization is applied to identify optimal congurations of multistage separation networks and study their sensitivity to parameter values. Superstructure optimization is conducted for countercurrent cascades and also for general superstructures to identify new multistage congurations. Results show substantially reduced separation eort for alternative congurations in large parameter regions, specically in regions where optimal countercurrent cascades have a low number of stages. General, simple design guidelines for multistage separation with a low number of stages are derived from rigorous global optimization by comparing results for dierent processes.
