Implantación y evolución de un humedal artificial de flujo subsuperficial en Cogua

The subsurface flow constructed wetlands are considered an economic technology to treat domestic wastewater. They represent an interesting potential of application to the Colombian conditions. This article presents the functioning of this particular type of wetlands, during its initial stages, based on the experience obtained from one designed for the “Estación Experimental Javeriana”, located in Cogua, Cundinamarca. The designed wetland treats used water from houses and school facilities. The article presents a comparison between the results obtained experimentally and those pre-established by diverse design models. It is found that the Model from Reed et al, shows the best adjustment to the experimental results. This information will be the basis to the adaptation of this technology for the specific Colombian conditions.
