Artificial wetlands
Constructed wetlands are water treatment systems that mimic the purification processes present in natural wetlands. These systems are part of the non-conventional, low-consumption wastewater treatment technologies. They are based on the interaction between phytoremediation (plant action) and microbiological processes.
Artificial wetlands are purification systems that reproduce the water treatment processes, specifically the reduction of contaminants that take place in natural wetlands. Artificial wetlands belong to the so-called non-conventional technologies, or low-consumption technologies for wastewater treatment. In addition, these systems are classified as a type of ecological treatment, in which phytoremediation and microbiological treatment are interrelated. The wetland has small rocks such as gravel or rubble that function as a filter and sedimentation system. Then, the roots of the plants are responsible for the fixation, assimilation and adsorption of certain contaminants. Meanwhile, microorganisms are responsible for the reduction, denitrification and elimination of certain pathogens.
