Treatment of landfill leachate by reverse osmosis
TLDR
In this paper, an experimental study describing the treatment of landfill leachate by means of a pilot-scale reverse osmosis unit was conducted. But the results showed that the rejection coefficient of COD was practically independent of the COD value, but was significantly affected by the applied pressure.About:

Physico-chemical treatments for removal of recalcitrant contaminants from landfill leachate.
TL;DR: None of the individual physico-chemical techniques is universally applicable or highly effective for the removal of recalcitrant compounds from stabilized leachate, but adsorption, membrane filtration and chemical precipitation are the most frequently applied and studied worldwide.

Leachate Minimization by Reverse Osmosis
TL;DR: In this paper, an untreated leachate flow is concentrated thirteen times by tubular type reverse osmosis and the particle-free permeate meets the effluent requirements for direct discharge to virtually any watercourse.

Abstract: The mechanism of mass transfer and the membrane selectivity of reverse osmosis are discussed by the solubilisation-diffusion model. Factors affecting in one hand both solvent and solute rate permeation and in the other hand the membrane's selectivity are developed. The difference between reverse osmosis and ultrafiltration is due to the fact that in ultrafiltration the separation is controled by the size of pores (steric mechanism) since in reverse osmosis the solubilisation-diffusion through the membrane is the controling one. Some basic considerations about nanofiltration (or reverse osmosis at low pressure) are considred besides Le mecanisme du transfert de matiere et la selectivite membranaire sont differents lorsque l'on passe de l'ultrafiltration a l'osmose inverse. Il y a exclusion sterique, par la taille des pores de la membrane en ultrafiltration, alors qu'en osmose inverse c'est la solvatation des solutes dans la membrane qui intervient majoritairement. On fait le point sur les mecanismes de transfert en osmose inverse et on developpe tout particulierement le modele du transfert par solubilisation-diffusion en mettant l'accent sur l'importance des coefficients de partage sur la selectivite globale de la separation
