What would be an example of a physical means used to treat both waste water and drinking water?

An example of a physical means used to treat both wastewater and drinking water is filtration. This process involves passing water through a filter medium, such as sand or activated carbon, to remove suspended solids, impurities, and contaminants. Filtration can effectively reduce turbidity and improve the clarity and quality of both types of water, ensuring safety and cleanliness. Additionally, it is often a preliminary step in more advanced treatment processes.
