Consultancy Assignment: Tree Nursery, Belgium
A constructed wetland was designed to treat the irrigation runoff from the container plant production. The treated water will be collected in a water reservoir and reused as irrigation water. This system will result in a decrease of the groundwater consumption with 35% per hectare production area.
Main objective of the constructed wetland is the removal of fungal spores. A secondary objective is the removal of nutrients.
