Treatment of Landfill Leachate by a Combined Anaerobic Fluidized Bed and Zeolite Column System

Feasibility analysis of color removal from textile dyeing wastewater in a fixed-bed column system by surfactant-modified zeolite (SMZ)

“…Thus, higher color intensities resulted in quick exhaustion of sorption sites, making the uptake less effective. Similar results were found for ammonia removal from landfill leachate by zeolite fixed-bed column [42] and As(III) removal in a fixed-bed system by modified calcined bauxite (MCB) [43].…”

Ammonium removal from sanitary landfill leachate using natural Gördes clinoptilolite

“…The increasing of treatment efficiency was due to the replacement of calcium, potassium and magnesium exchangeable ions from natural clinoptilolite structure by sodium ions during regeneration. Turan et al (2005) states that the regeneration expands the size of micropores and enables the increasing the number of ammonium ions accessing more ion exchange sites within the clinoptilolite [21].…”

The effect of landfill leachate composition on organics and nitrogen removal in an activated sludge system with bentonite additive

“…A combination of chemical (coagulation-flocculation, chemical oxidation, ozonation), physical (adsorption on activated carbon, zeolites, membrane techniques, air striping) and biological steps are often required (Ahn et al, 2002;Poitel et al, 1999;Rivas et al, 2003;Turan et al, 2005). Biological processes play an important role within the integrated systems (Bohdziewicz et al, 1999); the biological nitrification and denitrification in an activated sludge (AS) system is one of the most feasible, effective and economical methods for the removal of nitrogen, not only from municipal wastewater, but also from leachates (Ilies and Mavinic, 2001).…”
