... Furthermore, wastewater with concentrations of 1000 ppm, 2000 ppm, 500 ppm, 2000 ppm, and 1000 ppm, respectively, shows elevated levels of alkali, total dissolved solids (TDS), chloride, total suspended solids (TSS), and sulfate, indicating that it is suitable for concrete production [6]. There are numerous ways to treat wastewater, and Figure 1 shows a flow diagram that breaks down the various steps of treatment in the effluent treatment process [7]. Sewage water typically comprises 0.10% of biological and inorganic particles, which settle and are insoluble. ...

Limited water supplies, primarily from the rapid expansion of industry like tanneries, stone quarries, and concrete manufacturing, provide problems for the public's access to clean water. These sectors not only use a lot of freshwater, but they also generate a lot of garbage of different kinds. The impacts of wastewater on the fresh and rheological characteristics of concrete are thoroughly investigated in this study. It pinpoints possible causes of the degradation of concrete qualities when it comes into contact with wastewater. The dearth of studies on the integration of wastewater into the manufacture of concrete emphasizes the pressing need for novel approaches and techniques in this area. It has been noted that adding wash water reduces the workability of newly mixed concrete.

... Among the existing methods for energy recovery from wastewater, anaerobic digestion for biogas production stands out as the most widely adopted approach (Obileke et al., 2021). However, other promising alternatives focus on generating green hydrogen as an energy carrier (Guo et al., 2019). Hydrogen has a higher energy content per unit mass compared to biogas and contributes to reducing the carbon footprint. ...
... Literature classification through word mining, also known as cooccurrence analysis, is a technique used to identify patterns and relationships among words and terms in a large body of text . One commonly used tool for this type of analysis is the VOSviewer software, which can be used to create visualizations of co-occurring terms (Guo et al., 2019). To perform this type of analysis, a large corpus of text is typically gathered, such as a set of scientific articles or books on a particular topic (Chen et al., 2023). ...
public health. The research aims to comprehend the current state of industrial wastewater management, pinpoint gaps, and outline future research prospects. The SLR methodology involves scouring the Scopus database, yielding an initial pool of 253 articles. Refinement via search code leaves 101 articles, followed by abstract screening that reduces articles to 79, and finally 66 well-focused articles left for thorough full-text examination. Results underscore the significance of regulatory frameworks, technological innovation, and sustainability considerations as cornerstones for effective wastewater management. However, substantial impediments like; inadequate infrastructure, resource constraints and the necessity for stakeholder collaboration still exist. The study highlights emerging research domains, exemplified by advanced technologies like nanotechnology and bioremediation, alongside the pivotal role of circular economy principles in wastewater management. The SLR offers an exhaustive view of contemporary industrial wastewater management, accentuating the imperative of an all-encompassing approach that integrates regulatory , technological, and sustainability facets. Notably, the research identifies gaps and opportunities for forthcoming exploration, advocating for interdisciplinary research and intensified stakeholder collaboration.

This chapter investigates the conversion of wastewater into sustainable energy through the use of novel methods such as anaerobic digestion, microbial fuel cells, geothermal desalination, and internet of things (IoT) integration. It underlines the significance of wastewater treatment and energy sustainability, as well as the need for cost-effective solutions. IoT for real-time data collecting, analysis, and control can help with sustainable wastewater treatment and energy generation. Anaerobic digestion generates biogas, whereas microbial fuel cells convert organic molecules into energy. Geothermal desalination provides low-cost energy efficiency. IoT and ML technology enhances performance, lowers energy consumption, and allows for remote monitoring and maintenance, all of which contribute to a more sustainable and resilient future
... In the past decade, the photocatalysis technology has mushroomed into the limelight, which is considered to be one of the most promising green and efficient approaches for directly harnessing renewable solar energy [10]. Compared with the traditional methods discussed above, photocatalysis has the advantages of simple operation, mild conditions and high energy efficiency [11][12][13]. Among the numerous photocatalysts, TiO 2 as the most representative material has received much attention for the reasons such as corrosion resistant, non-toxicity, and low cost [14,15]. ...
In order to protect water bodies and prevent water pollution, the direct use of clean solar energy to degrade the organic dyes in industrial wastewater into innoxious products is a potential strategy and a trending topic. Recently, the lead halide perovskites have been intensively investigated as photocatalysts on account of their unique photoelectric properties. Unsatisfactorily, the lead toxicity and instability of these materials cause irreversible harm to the ecology and low long-term degradation efficiency, limiting their practical applications. For the first time, lead-free double perovskite Cs 2 SnCl X I 6-X microcrystals were prepared by solution supersaturation recrystallization method for the photocatalytic degradation of Sudan Red III. The optical band gaps of the Cs 2 SnCl X I 6-X microcrystals were adjustable from 4.48 to 1.34 eV upon halogen regulation, while the photo-degradation performance of Cs 2 SnCl 4.1 I 1.9 was even much higher than the recently reported composite photo-catalysts under similar conditions. Furthermore, the recycling and storage experiments demonstrated the reusability and excellent environmental stability of the as prepared Cs 2 SnCl X I 6-X microcrystals. Based on the results of the free radical trapping tests and electron paramagnetic resonance measurements, the mechanism for the photocatalytic degradation process were discussed in details.

The rapid technological advancement of the manufacturing sector over the past few decades inevitably led to the rise of Industry 4.0. It has the potential to significantly alter how globalisation is practiced in the production and consumption of products and services across international markets. In this chapter, we'll take a closer look at the rise of Industry 4.0 and the new technical architecture that underpins it, as well as the benefits it's expected to bring.In addition, how we may use technology to fortify a company's competitiveness and shield it from the perils of this transformation. The new global division of labour, the worldwide supply chain, and the global value chain will all be profoundly affected by this multifaceted technology, as evidenced by a thorough examination of the relevant literature. It will alter the competitive landscape by shifting the advantage away from large corporations and toward small and medium-sized enterprises (SMEs) in emerging markets and developed markets. As human and technological skills advance quickly, businesses may be able to profit.
