State of art: A current review of the mechanisms that make the artificial wetlands for the removal of nitrogen and phosphorus

Abstract

Constructed wetlands for wastewater treatment are used as green technology, resulting from the need to replicate the ecological benefits of natural wetlands to treat various tributaries of wastewater. This work is a literature review of the different types of constructed wetlands and their treatment processes. Many studies have been conducted on constructed wetlands, but a synergy of this information remains to be done. However, although constructed wetlands are a common management practice for mitigating pollutants from agricultural and municipal runoff, many countries do not have comparative studies of the effectiveness of disposal, maintenance neither extensive research on alternative substrates nor preventive measures to avoid substrate clogging.
