Currently, artificial wetlands have been promoted for wastewater treatment. These wetlands simulate the conversion of organic matter and nutrients, in which microorganisms attached to the support medium and plants act as active agents in the treatment. However, flooded soils have anaerobic conditions that favor the production of methane, a greenhouse gas with a global warming potential 21 times greater than that of CO2. Therefore, a HSSFW (horizontal subsurface flow wetland) was installed to evaluate its efficiency by determining the COD (Chemical Oxygen Demand) and the CH4 generated, using a gas chromatograph. The analysis revealed a maximum methane emission of 10.32% over a period of 79 days, or 23 hydraulic retention times, and a 72.52% organic matter removal rate, measured as COD, was achieved, concluding that it is an efficient system and that artificial wetlands are analyzed from the perspective of climate change mitigation and energy utilization.
