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. Filtration is a process that uses a physical barrier to remove particles from a liquid. In water treatment, filtration is used to remove suspended solids, bacteria, and other microorganisms from water. Filters can be made of various materials, such as sand, gravel, activated carbon, or membranes.

In wastewater treatment, filtration is often used as a secondary treatment process. After wastewater has been treated in a primary treatment process to remove large solids and organic matter, it can be filtered to remove smaller particles. Filtration can also be used in drinking water treatment to remove particles and microorganisms from source water before it is disinfected.

Filtration is a versatile water treatment process that is effective in removing a wide range of contaminants. It is also relatively simple to operate and maintain, making it a cost-effective treatment option.
