The objective of the present work is to evaluate the treatment capacity of the unsaturated zone (UZ) to remove contaminants from a wastewater effluent using a vegetation filter. The wastewater effluent originates from an office building and it is characterized by a high organic carbon and nitrogen load. Prior to its application over the vegetation filter, the raw wastewater is primary treated with an Imhoff tank. The vegetation filter surface is 77 m2 and it has been designed with an intensive plantation density (10,000 plants/ha) to maximize the plants nutrients uptake. The system efficiency has been controlled with a Gee Passive Capillary Lysimeter installed at 90 cm depth that allows a periodical sampling of the infiltrating water through the UZ. Furthermore, the potential groundwater affection derived from the wastewater application was monitored in a downgradient piezometer. The vegetation filter presents a high contaminant removal: up to 85% in terms of concentration in the cases of chemical oxygen demand (COD) and dissolved organic carbon (DOC), 90% for total phosphorus (PT) and 73% for total nitrogen (NT). When the efficiency is evaluated in terms of mass, the values are much higher, reaching 90% of removal for NT. No significant affection was observed in groundwater quality as a consequence of the leaching from the vegetation filter.
