“…The anaerobic treatment involves anaerobic bacteria that transforms the organic matter present in the wastewater into biogas, which contains large amounts of methane gas and carbon dioxide. The anaerobic treatment is preferred when the dissolved organic concentrations of untreated wastewater are high [21]. The number of stages required to treat wastewater greatly depends on the extent of pollutant to be eliminated and the mechanism of elimination [27].…”

“…The major sources of wastewater are domestic wastewater, agricultural waste, industrial waste, and commercial waste [ 19 ]. Almost all the major sources need good quality water, particularly industries, but in return a huge volume of contaminated and polluted water is generated and streamed in large water bodies, making them polluted [ 20 , 21 ]. Different sources of wastewater are shown in Figure 1 .…”

Clean and safe water is a fundamental human need for multi-faceted development of society and a thriving economy. Brisk rises in populations, expanding industrialization, urbanization and extensive agriculture practices have resulted in the generation of wastewater which have not only made the water dirty or polluted, but also deadly. Millions of people die every year due to diseases communicated through consumption of water contaminated by deleterious pathogens. Although various methods for wastewater treatment have been explored in the last few decades but their use is restrained by many limitations including use of chemicals, formation of disinfection by-products (DBPs), time consumption and expensiveness. Nanotechnology, manipulation of matter at a molecular or an atomic level to craft new structures, devices and systems having superior electronic, optical, magnetic, conductive and mechanical properties, is emerging as a promising technology, which has demonstrated remarkable feats in various fields including wastewater treatment. Nanomaterials encompass a high surface to volume ratio, a high sensitivity and reactivity, a high adsorption capacity, and ease of functionalization which makes them suitable for application in wastewater treatment. In this article we have reviewed the techniques being developed for wastewater treatment using nanotechnology based on adsorption and biosorption, nanofiltration, photocatalysis, disinfection and sensing technology. Furthermore, this review also highlights the fate of the nanomaterials in wastewater treatment as well as risks associated with their use.

In all parts of the world, water is rapidly becoming an emerging issue. Mature technologies had been established in the water treatment process to overcome the issue. However, the water treatment technology advance does not mean it is not faced with its issues. In fact, it still leaves many problems for humans due to both technical issues and management problems. Understanding the water treatment process's proper perspective is required to achieve sustainable and equitable development for Muslim countries. In the other hand, Islam endeavors comprehensive guidelines on all aspects of human life and manages water resources. This mini-review article will give a brief explanation of some excellent technologies of water treatment and challenges associated with the advancing control over their beneficiation. Therefore, an Islamic perspective will be addressed to emphasize how Islamic-based policy and management can take a leading solution to overcome the fundamental problem for the future of water for the benefit of human life.

“…Common remediation strategies include biological treatment, coagulation-flocculation, in situ burning, and physical oil/water separation. Among them, physical collection/separation with absorbents or filters excels in high efficiency, secondary pollution-free, and potential for oil reclamation [3][4][5][6][7][8]. Synthetic porous materials and carbon-based sponge have been extensively investigated for oily wastewater remediation [9,10].…”

The novel wettability switchable cellulose nanofiber- (CNF-) based aerogel was conveniently prepared by polydopamine mediated composition of CNF and n-dodecanethiol. The wettability of aerogels can be controlled by adjusting the PDA and n-dodecanethiol loading content, which leads to a variation of water contact angle from 0-149°. The PDA was coated on cellulose nanofibers via hydrogen bonds and then n-dodecanethiol was anchored onto the scaffolds by Michael addition reaction, which was revealed by XPS and FTIR spectra. The composite aerogel can selectively absorb a series of oily liquids from the oil/water mixture, with the maximum absorption capacity of 68 g/g. This work presented a facile strategy to prepare wettability switchable CNF-based heterogenous aerogel and exhibited the potential of the composite aerogel for oil/water separation.
