This NBS consists in an innovative wetland surface, which can provide electricity through microbial fuel cell technology. Electro wetland requires low construction/installation and low operational costs and can treat different types of wastewaters (domestic, industrial, etc.) with different pollutants and loads. The system can provide electricity to feed the irrigation of nearby gardens and illumination in market entrance.
This NBS can be built on any place that generates wastewater with a significant content of organic matter. Load requirements of the supporting surface must be taken into consideration in order not to generate any structural affection in urban areas. Depending on the wastewater being treated each Electrowetland will have different characteristics (grain size, total surface, bed depth, etc.). Depending on its configuration (surface unit vs excavated basin) its affection when removed will vary.
The Electrowetland get the recovery of the investment between the 10 and the 20 years.
