“…The microorganisms are either attached or suspended in macroporous filters, while membrane biofilters can be submerged into wastewater or installed at the side stream. Santos and Daniel (2020) reviewed the activated carbon filters developed for water and wastewater treatment. The biofilm formation and activity are influenced by the feed water quality, backwashing, hydraulic conditions, and temperature.…”

Rapid development, urbanization, and population growth have contributed to water stress in many parts of the world. As freshwater sources are finite, it is essential to source for alternatives to ensure water security. Reclamation of non‐conventional water sources (i.e., rainwater and greywater) can be a viable alternative to alleviate water stress. In this work, various laboratory, pre‐commercialization scale, and commercialized products for rainwater harvesting and greywater treatment and reuse were reviewed. As a result, a conceptual framework is proposed to provide an overview on the applicability of technologies under various settings, which were mapped against the intended use of treated water and the potential for water supply expansion. This conceptual framework could aid decision makers in deciding on a suitable decentralized solution for water reclamation depending on limiting criteria. Decentralized systems of rainwater harvesting and greywater treatment for reuse are going to be crucial in reducing the dependence on the centralized water supply.

“…Due to the toxicity of aniline to ecological organisms, aniline has been listed in the "blacklist of China's environmental priority pollutants, " which requires strict control in industrial drainage. At present, the treatment of aniline waste water at home and abroad mainly includes physical, chemical and biological methods (Fan et al, 2017;Ke et al, 2018), and the research results in recent years show that biological enhanced treatment is one of the important ways to eliminate amine in the environment (Weiwei et al, 2017;Santos and Daniel, 2020). Bioaugmentation technology can effectively remove target pollutants (Weiwei et al, 2019), accelerate system startup (Abbaslou et al, 2018), improve the system's ability to resist hydraulic and organic loads (Jasper et al, 2017), and enhance the stability of system flora structure and function (Ying et al, 2018).…”

With the development of modern chemical synthesis technology, toxic and harmful compounds increase sharply. In order to improve the removal efficiency of refractory organic matter in waste water, the method of adding powdered activated carbon (PAC) to the system for adsorption was adopted. Through the analysis of organic matter removal rule before and after waste water treatment, it can be found that PAC is easy to adsorb hydrophobic organic matter, while activated sludge is easy to remove hydrophilic and weakly hydrophobic neutral organic matter. Powdered activated carbon-activated sludge SBR system (PAC-AS) system is obviously superior to AS and PAC system in removing organic matter of hydrophilic and hydrophobic components, that is, biodegradation and PAC adsorption are additive. Compared with the control system, the Chemical Oxygen Demand (COD) removal rate of refractory substances increased by 8.36%, and PAC had a good adsorption effect on small molecular weight organic compounds, but with the increase of molecular weight of organic compounds, the adsorption effect of PAC gradually weakened, and it had no adsorption effect on macromolecular organic compounds. Based on the research of fuzzy control theory, an Agent control system for ozone oxidation process of industrial waste water based on Mobile Agent Server (MAS) theory was established, which was realized by fuzzy control method. The simulation results showed strong stability and verified the feasibility and adaptability of the distributed intelligent waste water treatment system based on MAS theory in the actual control process.

“…A large amount of AC is used to remove the organic impurities contained in electroplating solutions for metal finishing. It is also widely employed in environmental processes, such as drinking water filtration, volatile organic compound (VOC) capture, mercury scrubbing from coal-fired power plants, and air purification [24][25][26][27][28][29][30][31]. ACs are generally produced by carbonization at temperatures in the range of 600-900 • C in an inert atmosphere from source materials such as bamboo, coconut husk, wood, coal, and willow peat.…”

Hypersonic aircrafts suffer from heat management problems caused by the air friction produced at high speeds. The supercritical catalytic cracking of fuel is endothermic and can be exploited to remove heat from the aircraft surfaces using specially designed heat management systems. Here, we report that an acid/base-treated activated carbon (AC) catalyst shows superior performance to the conventional ZSM-5 catalyst at 4 MPa and 450 °C. Further, under these conditions, coke formation is thermodynamically avoided. Of the prepared catalysts, the AC catalyst treated with NaOH and subsequently with HNO3 (denoted AC-3Na-N) was the most active catalyst, showing the highest selectivity toward light olefins and best heat sink capacity. The acid/base-treated ACs and ZSM-5 catalysts were characterized by scanning transmission electron microscopy, X-ray photoelectron spectroscopy, NH3 temperature-programmed desorption, and Fourier-transform infrared spectroscopy measurements. Characterization reveals the importance of acid strength and density in promoting the cracking reaction pathway to light olefins observed over the acid/base-treated AC catalysts, which show comparable activity at 450 °C to that of the ZSM-5 catalyst operated above 550 °C. The low-temperature activity suppressed coke and aromatic compound (coke precursors) formation. The stability of the acid/base-treated activated carbon catalysts was confirmed over a time-on-stream of 30 min.
