Do all the Anaerobic Digesters Operate in the Same Way?
While the basic operating principle remains the same, different types of anaerobic digester technologies are commercially available. Choosing a type of digester technology depends on the type of feed material, retention time, solid contents and cost. Covered lagoons, complete mix, plug flow and attached growth/fixed film are some of the common types. Covered lagoon digesters may not be suitable for Alberta as the atmospheric temperature in winter is extremely low.
