“…The high levels of organic matters and toxic materials such as heavy metal ions in municipal landfill leachate and industrial wastewaters resulted in environmental problems for plants, animals, and human's health (Gautam et al, 2015;Karri, Sahu, & Chimmiri, 2018;Koushkbaghi et al, 2018). The presence of high concentrations of chemical oxygen demands (COD) and heavy metals in wastewater and following groundwater has negative effects on the food chains which could be resulted in various diseases in the kidney, gastric, liver, brain, and nervous system of humans and animals RESEARCH ARTICLE (Nasrabadi, Bidhendi, Karbassi, & Mehrdadi, 2010;Reyad, 2017;Yonten, Alp, Yildirim, Yildirim, & Ogedey, 2017;Zeng et al, 2015).…”

The removal of heavy metal ions and organic materials from wastewater due to their toxicity is necessary. In the present study, the titanium dioxide/zinc oxide (TiO2/ZnO) nanocomposite has been coated on the sewage sludge carbon (SSC) surface and its application was investigated for the adsorption of Ni(II), Cu(II), and chemical oxygen demands (COD) reduction from aqueous solutions and industrial wastewaters in Eshtehard, Iran. The effect of adsorption parameters in a single system such as TiO2/ZnO ratio, TiO2/ZnO concentration, pH, adsorbent dosage, contact time, ionic strength, temperature, and initial concentrations of Ni(II), Cu(II), and COD was investigated on the adsorption capacity of synthesized SSC/TiO2/ZnO adsorbent. The pseudo‐second order and Redlich–Peterson isotherm models were best described the kinetic and equilibrium data of Ni(II), Cu(II), and COD sorption. The maximum monolayer sorption capacities of Ni(II), Cu(II), and COD were found to be 62.3, 75.1, and 1,120.3 mg/g, respectively. The central composite design was used to investigate the interaction effects of pH and initial concentrations of Ni(II), Cu(II), and COD on the simultaneous removal of Ni(II), Cu(II), and COD from aqueous solutions in a ternary system. The potential of synthesized SSC/TiO2/ZnO adsorbent was investigated for Ni(II), Cu(II), and COD adsorption from industrial wastewaters of Iran. Practitioner points The novel sewage sludge carbon/TiO2/ZnO adsorbent was synthesized. Adsorption of Ni(II), Cu(II), and chemical oxygen demands (COD) from industrial wastewaters was investigated. Maximum Ni(II), Cu(II), and COD sorption capacities were 62.3, 75.1, and 1,120.3 mg/g. Simultaneous removal of Ni(II), Cu(II), and COD was investigated in a ternary system.

“…Zeolite -aluminosilicate hydrate minerals with a porous, three-dimensional crystal structure are considered an excellent ion-exchange material because of their high selectivity for NH 4 + due to their microstructure 3 . An adsorbent of natural zeolites possesses a polar surface and is therefore able to attract ammonium ions quickly and effectively 2 . The removal of ammonia from water was carried out by using natural and synthetic zeolites.…”

In the petroleum industry during a catalytic cracking process, the used zeolitic catalyst becomes waste. this article investigated the sorption capacities of ammonium ions from aqueous solutions onto the previously mentioned zeolitic waste by batch experiments. Three types of zeolitic waste were used: unmodified zeolitic waste with two different particle size distributions and H 2 o 2-modified zeolitic waste. Several techniques, including X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET) multilayer adsorption theory measurements, and X-ray fluorescence analysis (XRF) were used to demonstrate experimentally that the zeolitic waste could be used as a sorbent for the water decontamination of NH 4 + ions. The morphology of zeolitic waste investigated by scanning electron microscopy (SEM) revealed particles with a spherical shape. The nitrogen adsorption-desorption isotherms showed an isotherm mixture of types I (pure microporous) and IV (mesoporous). This suggested that the investigated zeolitic materials were mesoporous (4.84 nm) and microporous (0.852 nm), as well as containing slit/cylindric pores, according to a quench solid density functional theory (QSDFT) adsorption branch model. Zeolitic waste from the oil industry showed good NH 4 + sorption properties (removal efficiency of 72%), thus becoming a potential adsorbent to be used in the treatment of contaminated aqueous effluents polluted with ammonium ions. Simultaneous waste and water decontamination can be achieved, providing a new tool and enhanced capabilities for environmental remediation. Ammonium (NH 4 +) is one of the common form of reactive nitrogen in wastewater 1 , and its contamination in fish causes serious health problems due to its high toxicity. The technologies for ammonia removal from wastewater are based on physicochemical and biochemical treatment methods 2. One of these treatment methods is adsorption, which is a low-cost process. Different adsorbents, such as wheat straw biochars, pine sawdust or zeolites, can be effective in adsorbing ammonium in wastewater 3-13. Yang et al. 4 used some natural adsorbents such as pine sawdust and wheat straw biochars for the ammonium removal in wastewater. It was concluded that biochars can be efficient absorbents for NH4 + removal from aqueous solutions. Tian et al. 5 synthesized a new sorbent using modified coal cinders and zeolite powders. This sorbent has been shown to be a good material for the removal of ammonia nitrogen. The removal efficiency of ammonia nitrogen was 67.3% and 71.3%. The inflow concentrations of ammonia nitrogen were obtained under the experimental conditions where chemical oxygen demand under a water flow of 10 L/h. Yin et al. 6 used NaCl-modified clinoptilolite as adsorbent for the nitrogen removal. Results in a current batch study provided that the maximum ammonium sorption capacity of clinoptilolite was in the range of 6.64 to 7.27 mg. N/g. The work reported by Sánchez-Hernández et al. 7 evaluated the use of NaP1 ze...

“…air stripping, is applicable to concentration levels of 10-100 (mg/l). Higher ammonia content requires alternative removal technique (Karri et al 2018). Biological process in particular nitrification and denitrification methods is poor in removing ammoniacal nitrogen due to longer treatment time and low rate of removal efficiency (Sabumon 2007;Ge et al 2014).…”

“…The task of providing proper treatment facility for the removal of ammoniacal nitrogen (NH 4 -N) from the wastewaters from the dye intermediate industry is not only difficult but also expensive too; hence, there is a strong need of a new or modified technology which overcomes the limitations of the conventional methods (Hasanoglu et al 2010;Karri et al 2018). Advanced oxidation processes (AOPs) drew the attention of researchers for its advantages as it works in ambient temperature and pressure, it has less reaction time and is more economical and feasible than conventional methods (Guedes et al 2003;Khatri et al 2018;Zhang and Zhou 2019).…”

The untreated wastewater from the dye industry having high ammoniacal nitrogen and chemical oxygen demand (COD) significantly pollutes the receiving water, such as a river, having major ill implications on the aquatic environment. The present study is undertaken to address this problem. It investigates the effectiveness of Fenton reagent in simultaneous treatment (removal) of ammoniacal nitrogen and COD present in the wastewater by varying the parameters like pH, concentration of Fe 2+ and H 2 O 2 and their molar ratio. The reaction time for all the experiments was kept 60 min. The experimental analysis in terms of calculating the residual % of ammoniacal nitrogen and COD revealed that the maximum reduction occurred at pH 3. At this pH, further set of experiments were performed by varying the molar doses of Fe 2+ /H 2 O 2 as 1:1, 3:3 and 5:5, and the results reveal that the maximum reduction in both ammoniacal nitrogen and COD happens at molar dose of 3:3. To understand the effect of the concentration of Fe 2+ and H 2 O 2 on the respective removal efficiency, set of experiments were performed by taking the molar ratio of Fe 2+ /H 2 O 2 as 2:1, 3:1, 5:1, 1:2, 1:3 and 1:5. The experimental analysis reveals that the maximum reduction happened at molar ratio 1:3. Fenton process can mineralize the pollutants up to 75.8% and 78.6% for ammoniacal nitrogen and COD removal. The findings of the study would be of great use for planning and optimizing the wastewater treatment facility for the dye intermediate industry.
