“…Air stripping or aeration of wastewater has been reported since the beginning of the 20th century (98), mainly for the purpose of removing noxious compounds from the water. It was not until the 70'es that ammonia stripping from wastewater was seriously promoted (99)(100)(101). Large-scale installations were implemented at least 9-10 different places in the United States mainly for the purpose of removing ammonia from reject water following dewatering of digested sludge.…”

Excessive livestock production in small areas poses a risk of nitrogen release to the environment and thus air and water contamination. Recovery of ammonia is necessary to avoid overfertilization, but manure management of untreated slurry is costly and complex. The authors discuss ammonium fertilizer recovery from manure using membrane processes and physicochemical methods including technology and energy assessments. Currently, nanofiltration, reverse osmosis, membrane distillation combined with ultrafiltration, and air stripping are the best choices. The processes rely highly on selection of appropriate pretreatment, as residual particulates will lead to fouling of membranes and stripping towers hence affect the performance greatly.

“…Ammonia is widely used in the chemical industry; approximately 113 to 244×10 6 tons of ammonia is released annually through agricultural and industrial activities and wastes in the world. Wastewater from industries such as petrochemical, pharmaceutical, fertilizer, food and paper industries contains large amounts of ammonia and must thus be treated before being discharged into the environment [1][2][3][4][5][6][7]. Ammonium nitrate is one of the most important environmental pollutants with high levels in the wastewater of petrochemical industries, especially those producing ammonia and urea [8].…”

Due to the health effects of ammonia as an environmental pollutant, such as its odor, corrosion, algae phenomenon, etc., a method should be adopted to remove it from wastewater. In this study, removal of ammonia from hypothetical wastewater was investigated using adsorption on SWCNTs. The Design-Expert software was used to design the experiments and optimize the parameters that are effective in the adsorption performance of carbon nanotubes (CNTs), such as contact time, adsorbent dosage, pH, temperature, and ammonia concentration. The results revealed that the maximum adsorption with a performance of 90% was attained at a pH of 9.5. In addition, the adsorption performance was enhanced by increasing adsorption time and adsorbent dosage. Furthermore, increasing the temperature and the adsorbate quantity led to a decrease in the adsorption performance.
