suitable for drinking. Human and industrial activities are causing pollution in two percent of the water, resulting in the presence of pollutants. (Kumar Reddy, D. H., & Lee, S. M. (2012))
Water is a primary global resource. The water scarcity is a result of the swift progress of urbanization, population expansion, agricultural advancement, industrialization, and many environmental concerns stemming from chemical and biological impurities in water, which transform it into pollution. Efficient waste management is crucial in order to prevent environmental and social issues. Wastewater treatment is a process that converts wastewater into useful resources suitable for both home and urban agriculture. Approximately 38,354 million litres of sewage are produced daily, although only a small fraction undergoes treatment. During wastewater treatment, the primary stage encounters many challenges caused by the accumulation of solid particles in the wastewater, leading to blockage. To address this issue, initial pretreatment is carried out to minimize the presence of these solid particles. Wastewater management is crucial in enterprises primarily due to the potential environmental impact of toxic effluent from industrial waste. It can pose a threat to aquatic creatures and contribute to the presence of toxins and pollution. Several techniques can be employed to treat wastewater, including the utilization of algal technology. This involves the cultivation of algae to treat wastewater produced by industries. The resulting algae can be further utilized in the manufacturing of biofertilizers, biofuels, and other applications. Water management encompasses a wide range of applications, including but not limited to agriculture, the chemical industry, the tannery industry, immobilization, nanofiltration, carbon capture technology, microbial bioremediation, and other sectors. The benefits and drawbacks of various applications are discussed in this article.
According to a report from the World Health Organization (WHO), the use of contaminated wastewater for drinking, sanitation, and other uses has resulted in the death of 10 million individuals. (Divya, S., & Oh, T. H. 2022). The environment has undergone significant transformations in recent decades, and these changes are still ongoing. By the year 2050, the global population is projected to reach 9.8 billion individuals, with a significant majority residing in urban areas. The rapid expansion of cities, together with the impacts of climate change, is exerting more strain on essential resources such as water, raw materials, and energy. The dynamics of water quality, availability, and quantity are undergoing rapid changes. The preservation of natural resources and their optimal utilization is increasingly becoming a crucial concern for the public. The availability of clean and drinkable water is an essential foundation of human civilization, necessary for survival, well-being, and advancement of society. In light of increasing apprehensions regarding water shortage, pollution, and the necessity for sustainable resource management, water treatment plants play a vital role in safeguarding public health and maintaining environmental integrity. These facilities play a crucial role in ensuring that water, which is a limited and extremely valuable resource, is treated to meet strict quality standards before being distributed to households, businesses, and communities. The development of water treatment facilities reflects humanity's pursuit of technological advancement and commitment to environmental conservation. Conventional treatment methods, although somewhat efficient, encounter difficulties in dealing with the intricate assortment of toxins and pollutants that permeate our water sources. The synthesis issues of WWTN have been represented as mixed-integer non-linear programming (MINLP) and were resolved utilizing global optimization solvers. Zhang et al. (2014) created a framework for wastewater reuse by using a multi-objective optimization model. The evolutionary algorithm was employed to solve
