Potable reuse is a research area that involves treating wastewater to make it safe and suitable for drinking. This process typically includes advanced treatment steps such as filtration, disinfection, and possibly even reverse osmosis to remove contaminants and pathogens from the wastewater. Potable reuse has the potential to provide a sustainable and reliable source of water in water-stressed regions, as well as reduce the strain on traditional water sources. Research in this area focuses on improving treatment processes, evaluating the effectiveness of potable reuse systems, and addressing public health concerns and perceptions surrounding the use of recycled water for drinking purposes.
