Anergic flow filter

The upflow anaerobic filter or FAFA is an occasional component of treatment plants. The function of the filter, also called anaerobic reactor is intended to reduce the pollutant load of the wastewater. The served water is fed to the filter through the bottom, constructed in such a way as to distribute the flow uniformly throughout the filter section. The water to be treated is passed through a porous body (stone), bringing it into contact with a thin biofilm of microorganisms adhered to the surface, or flocculated, where the anaerobic degradation process is performed.

Anaerobic filters generally operate, with a reasonable contaminant charge removal efficiency, in the mesophilic temperature range, ie between 25 and 38 ° C. Sources
