Wastewater reuse refers to the process of treating and recycling used water for various purposes, such as irrigation, industrial processes, and even drinking water. This practice helps conserve freshwater resources and reduces the environmental impact of wastewater disposal. There are different methods of treating wastewater, including biological treatment, filtration, and disinfection. By employing these techniques, reclaimed water can be safely used in applications like agriculture and landscaping, contributing to sustainable water management and supporting communities facing water scarcity.
