“…NH + 4 + Ca − anorthite→NH 4 -anorthite + Ca 2+ . More albite and anorthite crystals provide more binding sites for adsorption of ammonia nitrogen ions, resulting in a significant increase in ammonia nitrogen removal rate even when the void ratio and specific surface area exhibit little change [25]. Therefore, ion exchange plays a dominant role in the adsorption process.…”

“…Under acidic conditions, the adsorption of ammonium nitrogen by the ceramic aggregate primarily occurred through cation exchange, while under alkaline conditions, the mechanism may have predominantly involved physical adsorption. Chen et al [25] synthesized a novel zeolitized ceramic aggregate using fly ash and iron tailings as raw materials and investigated the influence of pore size on the adsorption efficiency of ammonium nitrogen. Zeolites have been found in an alkali-activated fly ash base system [26], leading to the formation of macropores and mesopores in the ceramic aggregate.…”

This study aimed to develop a novel filtering medium ceramic aggregate prepared using municipal solid waste incineration (MSWI) fly ash and the fuel ash from coal power plants, together with small amounts of silicon carbide foaming agent and magnesia flux as additives. For the manufacturing process, the dosage of MSWI fly ash and the sintering temperature were optimized to maximize the performance of the resulting materials. Leaching test results indicated that the heavy metal concentrations in the ceramic aggregate were significantly below the limits proposed by GB5085.3-2007, demonstrating its safety for wastewater treatment. The ammonia nitrogen removal efficiency was assessed, and the removal rate of the developed ceramic aggregate was found to be 16.4% higher than that of zeolite, making it comparable to commercial ceramic aggregate. Scanning electron microscopy and X-ray diffractometer analyses were conducted on the ceramic aggregates. The ammonia-nitrogen-removing mechanism, attributed to adsorption and ion exchange, is discussed based on the microstructural analysis results.

The proliferation of different pollutants in waters caused by anthropogenic and industrial activities has become a significant global concern, as they cause many problems, like severe health and environmental harm. Searching for green materials for water removal entirely and efficiently in this context is challenging. In this sense, innovative materials based on industrial waste become an incredible alternative, as they are waste, disposable incorrect in the environment, low-cost, and need to be adequately discharged. Many innovative materials based on industrial waste were performed in the literature, as these eco-friendly alternatives have great potential for many applications, including wastewater treatment. This overview presents various research that demonstrated different innovative materials based on industrial waste, their physicochemical properties, different properties, the adsorption removal, and other wastewater treatment reported based on different models. Based on the literature, we have also demonstrated that innovative materials based on industrial waste exhibit an incredible potential for the adsorption of various pollutants in water, indicating their promising solution of low-cost adsorption removal for wastewater treatment. Finally, this overview shows that these sustainable materials present significant potential for use in wastewater treatment.

“…Therefore, the zeolite ceramsite might be a promising lightweight fine aggregate for removing VOCs in asphalt binders. However, most studies have focused on preparing zeolite ceramsite from industrial waste and the application of zeolite ceramsite in concrete [ 26 , 27 , 28 ]. To our understanding, quite a limited investigation has been done on the adsorption effect and mechanism of zeolite ceramsite on asphalt VOCs.…”

In order to meet the requirements of industrial-scale fixed beds and develop an excellent adsorbent for asphalt VOCs. Zeolite ceramsite containing binder was prepared and successfully applied to the inhibition of asphalt VOCs. The results showed that prepared zeolite ceramsite possessed a high degree of crystallinity, and its main crystal phase is zeolite. The micropores with a pore size of 0.88 nm dominated the pore size distribution of the material. The adsorption experiment of asphalt VOCs showed a lower VOCs adsorption effect of 8.72% at a small dosage of 5%, while at a large dosage of 50%, the adsorption effect of VOCs exceeded 45%. This might be caused by the quite small external specific surface area, which occupied only 8.3% of the total specific surface area, and the low intraparticle diffusion coefficient due to the micropores. Meanwhile, the kinetics diameters of most aromatic hydrocarbons, which were comparable to the pore size of micropores, and the increase in the intraparticle diffusion resistance of aliphatic hydrocarbon molecules were the important factors in obtaining high adsorption of aromatic hydrocarbons in asphalt VOCs. Furthermore, the results indicated that the particulate adsorbent with a microporous structure should be mixed into the asphalt as a fine aggregate rather than an asphalt modifier for better asphalt VOCs adsorption effect.
