“…The aqueous phase and gas are their primary products, upgrading these leads to secondary products such as electricity, chemicals, and biofuels. The wastewater treatment from these industries uses physiochemical methods with recent technology emerging as the membrane technology, which uses the principle of reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF), thus facilitating the treatment of wastewater [98,99]. Biologically induced chemical trans-formation is taking place in three pathways: anaerobic digestion, aerobic digestion, and ethanol fermentation [100,101].…”

This critical review report highlights the enormous potentiality and availability of renewable energy sources in the Gulf region. The earth suffers from extreme air pollution, climate changes, and extreme problems due to the enormous usage of underground carbon resources applications materialized in industrial, transport, and domestic sectors. The countries under Gulf Cooperation Council, i.e., Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates, mainly explore those underground carbon resources for crude oil extraction and natural gas production. As a nonrenewable resource, these are bound to be exhausted in the near future. Hence, this review discusses the importance and feasibility of renewable sources in the Gulf region to persuade the scientific community to launch and explore renewable sources to obtain the maximum benefit in electric power generation. In most parts of the Gulf region, solar and wind energy sources are abundantly available. However, attempts to harness those resources are very limited. Furthermore, in this review report, innovative areas of advanced research (such as bioenergy, biomass) were proposed for the Gulf region to extract those resources at a higher magnitude to generate surplus power generation. Overall, this report clearly depicts the current scenario, current power demand, currently installed capacities, and the future strategies of power production from renewable power sources (viz., solar, wind, tidal, biomass, and bioenergy) in each and every part of the Gulf region.

“…5 Traditional water treatment methods can treat pollutants in industrial wastewater and domestic sewage to some extent; however, they are largely limited by problems such as low efficiency, high energy consumption, high cost, and complex processes. 6,7 For example, the conventional chemical precipitation method is inefficient and uneconomic for low concentrations of heavy-metal ions and antibiotics in wastewater. 8,9 The membrane separation technology is an emerging and promising technology that uses separation membranes for the purification of wastewater.…”

“…Traditional water treatment methods can treat pollutants in industrial wastewater and domestic sewage to some extent; however, they are largely limited by problems such as low efficiency, high energy consumption, high cost, and complex processes. , For example, the conventional chemical precipitation method is inefficient and uneconomic for low concentrations of heavy-metal ions and antibiotics in wastewater. , The membrane separation technology is an emerging and promising technology that uses separation membranes for the purification of wastewater. Separation membranes can filter out most pollutants driven by pressure difference and concentration difference, and they have the advantages of flexibility, simple operation, high efficiency, energy saving, and environmental friendliness; therefore, they have been widely used in the field of water treatment in recent years. , However, after a long-time operation, the filtration membranes may cause membrane pollution and fouling, which will decrease the filtration efficiency and water flux.…”

Semiconductor photocatalysts and membrane separation technology have been widely used in the field of water treatment. Usually, the particles of traditional semiconductor photocatalysts are easy to aggregate, difficult to separate from the liquid phase after photocatalysis, and may even cause secondary pollution. On the other hand, the membrane separation technology is also facing the problem of sharp decreases in removal efficiency and water flux caused by the membrane fouling. However, it is an attractive and promising solution to combine two technologies of photocatalysis and membrane separation for high-performance water treatment. In this work, we have developed the calcium oleate precursor solvothermal method to synthesize ultralong nanowires (UNWs) of Caalendronate (Ca-ALN) complex for the first time. Experimental results and data analysis indicate that the as-prepared Ca-ALN ultralong nanowires are an n-type semiconductor with an energy band gap of 3.41 eV. A new type of multifunctional photocatalytic filter paper has been developed based on ultralong nanowires of Ca-ALN complex (Ca-ALN-UNWs) and cellulose fibers (CFs). The as-prepared Ca-ALN-UNW/CF photocatalytic filter paper exhibits multifunctions of photocatalysis, adsorption, and filtration, which can be used for high-performance treatment of the wastewater containing various pollutants such as heavy-metal ions, dyes, antibiotics, and bacteria. The active oxygen species produced by the Ca-ALN-UNW/CF photocatalytic filter paper under light illumination are determined by electron spin resonance, and the energy band gap and photoelectric properties of the material are tested by ultraviolet−visible diffuse reflectance spectroscopy and electrochemical workstation. The pure water flux of the Ca-ALN-UNW/CF photocatalytic filter paper is very high, which can reach 2230.5 L m −2 h −1 under a working pressure of 0.1 MPa. The Ca-ALN-UNW/CF photocatalytic filter paper is promising for various applications such as highly efficient water purification and in the biomedical field.

“…Sometimes, degraded byproducts are even more toxic in comparison to their parent compound (Yin et al, 2017). The presence of emerging contaminants (ECs) in the environment is of great concern due to their harmful impacts on one hand and great challenges in existing water treatment technologies in terms of their removal efficiency on the other hand (Ahmed et al, 2021;Zamri et al, 2021).…”
