INFLUENCE OF SUPPORT MEDIA IN ANAEROBIC FIXED-FILM BIOLOGICAL PROCESSES
Anaerobic fixed-film biological processes for wastewater treatment have been used for many years. Still, the influence of the support medium is not fully understood and contradictory statements are often found in the literature. The reason for this is the complexity and variation of the organic material normally found in the wastewater to be treated and the complex hydraulic condkions in the reactors.
In general, the support medium must be designed as to promote mbdng of gas and liquid. Thereby, shortcircuiting and large vertical liquid velocities can be avoided. Also, the medium must have a configuration, which prevents clogging. “Complete abstract not presented.”
