Behaviour of an anaerobic/aerobic pilot scale fluidized bed for the simultaneous removal of carbon and nitrogen

Description of a pilot installation for municipal wastewater treatment. The simultaneous elimination of organic carbon and nitrogen carried out by a fluidized bed reactor with aerobic and anaerobic areas. The presentation of experimental results corresponding to a model of the flow and behaviour of the above mentioned elimination of organic material and nitrogen. Presentation of information concerning the characteristics of COD, N-NH 3 , N-NO x , pH, Redox Potential and D.O. throughout the reactor. Levels of purification reached: COD S >80%; (BOD 5 ) S >90%; N-TKN>80%; N-N Total >70%.
