Resumen de Recuperación del amoníaco de aguas con concentraciones altas de nitrógeno: una contribución a la explotación económica de estaciones depuradoras de aguas residuales urbanas (E.D.A.R.)
The fact that up to 30% of the nitrogen to be removed, in the form of ammonia, is ploouting the inflow into sewage treatment plants as process water from sludge dewatering processes leads to the question whether this ammonium can be discharged from the works in a separate, optimized process. If it is possible to transform the ammonia into a reusable mate ria instead of destroying it by converting it into nitrogen, this process can be a successful! contribution to protect our environment. If additionally, the costs of such a recycling process for ammonia can compete with current nitrogen removal processes, this will become a method of chaise. The following article describes the basic principles of this physical, or rather physico- chemical process. As far as possible, cost comparisons are based on optimized plants, both in terms of energy consumption and process engineering considerations.
