Application of Wastewater in the Frame of Circular Economy; Irrigation of Agricultural Lands

A great number of examples for Circular Economy applications are knonw in the field of solid, recyclable waste treams. In this area a massive development can be adsorbed. Relativly fewer efforts are devoted to the reuse of liquid resources. But waste water treatment is a technology what could be also considered as a technology what is able to provide streams otherwise problematic and not valorized: nutrients for agricultural use. An example for that new concept is the reuse of waste water for irrigation. This application can reduce the water scarcity and so slow down the increasing demand for fesh and absolutely clean water.
