PROCESS FOR REDUCING THE NITROGEN CONTENT OF ZOOTECHNIC REFLUENTS

摘要

A process for reducing the nitrogen content of a zootechnic refluent comprises the following operative phases: placing the refluent in contact with a basifying agent in a reactor; generating a gaseous flow above the refluent and specifically above the free surface of the refluent drawing out of the reactor the gaseous current comprising the ammonia; recovering the ammonia from the gaseous current coming out of phase b) with formation of a purified gaseous current.
