Hydrodynamic behaviour of a pilot scale anaerobic baffled reactor treating SWINE wastewater from farming

January 2016

Swine effluents are among the high pollutants effluent generated by agro-industrial activities, and therefore, inappropriate discharge can initiate fatal processes, such as eutrophication, pollution, and asphyxia of the aquatic biota. In this regard, the anaerobic baffled reactor (ABR) is viewed as a potential bioreactor to handle swine effluents since the baffles play a key role in organic matter degradation. The...
