“…As a post-treatment of the advanced oxidation process, an additional adsorption process was carried out using a natural zeolite and 36, 99 and 18% reductions were observed for COD, ammonium and chloride, respectively. Ammonia removal from landfill leachate using natural and synthetic zeolites was investigated, where response surface methodology approach based on a three-factor three-level central composite design was applied to compare and optimize the removal of NH 3 -N from landfill leachate (Pauzan et al 2020). Under optimized conditions, clinoptilolite (2 g/L, 50 μm, and 50%) and Sigma 96,096 (4 g/L, 150 μm, and 50%) effectively removed 58.2% and 37.8% of NH 3 -N, respectively.…”

“…As the landfill age increases, this results in the decrease of organic concentration and the increase of ammonia nitrogen concentration in landfill leachate. There are three types of leachates which have been classified according to the landfill age as shown in Table 1 and the characteristics of landfill leachate used in the literature is presented in Table 2 (Turan et al 2005a(Turan et al , 2005bYalcuk & Ugurlu 2009;Martins et al 2017;Pauzan et al 2020;Scandelai et al 2020). Ammonium is the most significant long-term pollutant present in leachate while its concentration can reach up to 4,000 mg/L (Turan et al 2005a(Turan et al , 2005bLin et al 2007;Gunay et al 2008).…”

This review deals with low-cost nanoporous zeolites for the treatment of sanitary landfill leachate. Organic contaminants and ammoniacal nitrogen are significant parameters in landfill leachate treatment. Adsorption processes are regarded as promising alternative treatment options in this respect. Zeolites are aluminosilicate materials that are widely used in separation, ﬁltration, adsorption and catalysis. Natural zeolite is a low-cost and readily available form of zeolite and is a promising candidate to be used as an ion exchange material for ammonia and other inorganic pollutant removal from landfill leachate. In this review, adsorption isotherms and kinetic models in batch system are evaluated and adsorption design parameters of the fixed-bed system are presented. Studies on ammonia removal from landfill leachate via zeolites have been thoroughly investigated. Leachate treatment systems combined with zeolites are presented. Cost of zeolites are also reported in comparison with other adsorbents. The investigated studies demonstrate that activated zeolite can improve the removal of COD, NH3-N and color significantly compared to the case where raw zeolite is used. Moreover, the composite of activated carbon and zeolite is also favorable for ammonia removal according to reported findings, where best adsorptive removal is attained on the composite media (24.39 mg/g).

“…In the methylene blue and methyl orange adsorption process, the highest adsorption capacity was obtained with a small adsorbent weight. The adsorbent weight can increase the active side, thus allowing the active side to not interact with the adsorbate and cause a decrease in adsorption capacity [20].…”

<p>Waste from the textile industry is considered a potential source of environmental pollution, especially water, because it contains dangerous dyes. In this research, natural zeolite is an effective and efficient alternative to overcome pollution caused by methylene blue and methyl orange dyes. Activation of natural zeolite was carried out with 3 M HCl solution and was characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). Simultaneously, the methylene blue and methyl orange adsorption processes were studied in variations in the weight of the adsorbent, contact time, and pH. The concentration of dyes left in the solution was observed with UV-Vis Spectrophotometer. The results showed that the adsorption capacity of natural zeolite in absorbing methylene blue was 21.189 mg / g and methyl orange was 18.208 mg / g. The optimum conditions of dyes adsorption are achieved with successive adsorbent weights 0.3 g and 0,4 g, following contact times 60 minutes and 90 minutes, and successive pH 6 and 2. The adsorbent weight factor, contact time, and pH affect the adsorption of dyes by natural zeolite from Ende.</p>
