Natural wastewater treatment systems, such as wetlands and constructed wetlands, function by utilizing natural processes to treat wastewater. These systems mimic the processes that occur in natural ecosystems to break down contaminants and remove pollutants from wastewater. Wastewater flows through these systems, where plants, microorganisms, and soil help to filter out impurities, break down organic matter, and reduce harmful substances. Consequently, the treated water is cleaner and can be safely reintroduced into the environment.
