wetlands

A wetland creates a natural water filter with a highefficiency ecological water treatment system below. The constructed wetland achieves the combination of water purification and a landscape scene

Physical processes of filtration

- Occurs in the rootzone or rhizosphere of the vegetation and in the soils - Bioremediation uses living organisms to degrade, transform, mobilize, or immobilize contaminants, thereby reducing toxicity
