“…These observations are consistent with the results published by Li et al [40] and Guo et al [41]. The authors investigated the elimination of ammonium by CLI from China and USA and stated that there is no change in the elimination or loading in a pH range of 5 or 6 to 9.…”

Abstract:The supply of food to the growing world population requires an increasing amount of nitrogen fertilizers, which can be achieved both by the energy-intensive Haber-Bosch process and by recovering ammonium from wastewater. Within the scope of this work, it is investigated to what extent different clinoptilolites (CLIs) can be used as ion-exchangers for the removal of ammonium from highly concentrated solutions. To this end, finely ground CLIs with different grain sizes (EcoZeo 20 and CCP 20: 0-20 µm, Micro 200: 0-200 µm) were tested for their sorption properties by varying the parameters of the sorption solution (c 0 = 1000 mg NH 4 -N/L) such as pH, temperature, or contact time. All three CLIs tested were effective at adsorbing ammonium. In a pH range from 2 to 8, all CLIs were able to eliminate ammonium equally well. Furthermore, a contact time of 60 min was sufficient to achieve 84-88% of the maximum load. At a temperature of 34 • C, the highest loading was achieved (investigated range: 10-34 • C), indicating that the adsorption process of all CLIs was exergonic and endothermic. Especially for wastewater streams with high ammonium concentrations such as sludge water from wastewater treatment plants, CLI proved to be suitable to adsorb ammonium.

“…As the number of channels/cavities increased, the surface area and heterogeneous nature of the materials increased in the following order: NP (2.34 m 2 g À1 ) < MGMP (41.63 m 2 g À1 ) < HMP (53.11 m 2 g À1 ). The present observation is in agreement with the research studies conducted by Wang and Zhu [55] and Li et al [56].…”

“…Therefore, removal of ammonium from surface water and wastewater has been given great consideration [10]. Among various methods available for ammonium removal, ion exchange adsorption has received great attention from scientists with the development of high-efficient ion exchangers such as zeolite [11]. Moreover, several works related to low-cost ammonium adsorbents prepared from natural mineral [12] and industrial wastes [13] by means of a conventional hydrothermal method has been cited in literatures.…”
