Sustainable and integrated industrial wastewater treatment as a base of green industry 4.0

With the fast development of the global economy and population, there has been an increase in the amount of wastewater and industrial effluents being discharged into rivers and lakes, resulting in deterioration of water quality and a reduction in the availability of freshwater resources. A comprehensive discussion of the topic of Industrial Wastewater Treatment Integrated for Sustainable Green Industry 4.0, including the difficulties and possible solutions that may be encountered along the way, is provided in this article. According to the results of this study, industrial wastewater treatment that uses online/real-time water for quality monitoring and control has shown great promise in terms of quality monitoring and control when utilizing online/real-time water. Implementing such a system in industrial wastewater treatment may offer an early warning system for poor treatment while increasing the quantity and quality of the end product, both of which are desired outcomes.
