CANON(Completely Autotrophic Nitrogen Removal Over Nitrite) Process to Remove Nitrogen in The Constructed Wetlands

Constructed wetlands have been increasingly used as a low-energy 'green' technique since the mid-1990s, in the treatment of wastewater, driven by rising cost of fossil fuels and increasing concern about climate change. They are man-made systems or engineered wetland that are designed, built, and operated to emulate function of natural wetlands for human desires and needs. Among various applications of these wetlands, one area that is of significant importance is the removal of nitrogenous pollutants, to protect water environment and enable effective reclamation and reuse of wastewater. This report provides a current state of constructed wetland technology, focusing on CANON(completely autotrophic nitrogen removal over nitrite) process that existing types of wetlands, the mechanisms and kinetics of nitrogen removal, wetland design to system performance.
