Abstract (en)
[origin: WO2010015928A1] The invention describes a process for extracting the ammonia nitrogen from liquid waste, comprising the following operating steps: a) placing the waste in contact with a basifying agent in a reactor; b) generating an ionized gaseous flow above the waste and in particular above the free surface of the waste and driving a gaseous current comprising ammonia outside the reactor; c) recovering the ammonia from the gaseous current exiting from step b) with the formation of a purified gaseous current.
