This research project will focus on use of wastewater in agriculture, and how to prevent the environmental and health-related risks associated with such use in countries with water scarcity. It will particularly address the occurrence and removal of micro-pollutants in the wastewater, by use of two different removal methodologies in our tests; (i) barrier enhanced small-scale decentralized wastewater treatment systems (so called DEWATS), and (ii) soil amendments applied on top of the soil or mixed with the top layer of soil.
