Wastewater reclamation and reuse are critical components of modern sanitation, hygiene, and sustainable water management practices. Wastewater reclamation refers to the process of treating sewage or industrial effluents to a level where it can be safely returned to the environment or used for beneficial purposes. This process involves a series of physical, chemical, and biological treatments that remove pollutants, pathogens, and harmful substances, ensuring that the reclaimed water meets specific quality standards. The primary objective is to reduce the burden on natural water bodies, minimize pollution, and conserve freshwater resources, which are increasingly under stress due to population growth, urbanization, and industrial development. The concept of wastewater reuse is closely linked to reclamation. Reuse involves utilizing treated wastewater for specific purposes instead of discharging it into rivers, lakes, or the ocean. Reuse can be direct or indirect. Direct reuse occurs when treated wastewater is immediately used for applications such as irrigation, industrial processes, or cooling in power plants. Indirect reuse, on the other hand, involves discharging treated wastewater into natural water bodies, from which it is eventually extracted for use after natural purification. Reuse of treated wastewater not only contributes to water conservation but also supports sustainable urban and agricultural development while reducing environmental pollution. The treatment of wastewater for reclamation and reuse is a structured process involving several stages. Primary treatment removes large solids, debris, and settleable organic matter through sedimentation and screening. Secondary treatment employs biological processes, such as activated sludge systems or biofilm reactors, to degrade organic pollutants and reduce biochemical oxygen demand (BOD) and
