Successful and Non-successful Experiences with the Use of Treatment Wetlands in Mexico

Hybrid wastewater treatment system (municipal, including discharges of mining activity) through wetlands and stabilization lagoons, for a flow rate of 3 L/s. 5 years of operation.


Case studies of successful and non-successful experiences with the use of wetland treatment technology are shown in the presentation. Wetland sizing is analyzed, and how their geometry impacts the pollutant removal efficiency.
The presentation includes a study of kinetic constants, pollutant removal efficiencies, hydraulic evaluations (using tracers), experiences of treated water reusage, by-product generation (flowers, crops, etc.), impact of treated water on water bodies (macroinvertebrates assessment), treatment costs, and migration of stabilization ponds, to hybrid systems through wetlands and lagoons.
Experiences of wetland systems that were projected for a useful life of 20 years are shown, however they began to malfunction due to incorrect operation.

The crucial importance of socio-economic, political and cultural aspects in the implementation of this ecological technology is briefly highlighted.

It is concluded that all stages (design, construction, operation and maintenance) should be considered as an integral project, with the collaboration of all involved, where it should not be attended by different participants, in a dispersed and untimed way.

Presented by Ph.D. Armando Rivas Hernández
