A Study into the Effect of a Series of Shocks on a Pilot-Scale Anaerobic Filter

The imposition of more stringent industrial consents to discharge led to companies examining the potential of in-house treatment. ¹ Of the options available, high rate anaerobic digestion processes such as the Anaerobic Filter ² and the UASB ³ have inherent advantages over both aerobic and physical/chemical techniques. These include: low operating costs, low sludge yield and the production of a high grade fuel gas.
