<p>An alternating anaerobic contact system for treating wastewater through an apparatus including one enclosed vessel partitioned into two or more enclosed chambers wherein each chamber is flow connected to other chambers by conduits or an apparatus including two or more enclosed vessels wherein each vessel is flow connected to other vessels by conduits. Each apparatus comprises at least one conduit which allows for (1) an anaerobic liquor to flow between a pair of chambers or vessels and (2) for treated wastewater to be separated and collected from the anaerobic liquor. Each apparatus overcomes the degassification problems common to anaerobic contact processing by assuring that the partial pressures of each chamber or vessel remain consistent. Each apparatus, furthermore, performs the settling stage of anaerobic contact processing in either a separate chamber or vessel thereby eliminating the need for external tankage, pumps, and piping.</p> |
