Anaerobic wastewater treatment – the an-OPUR process

This is a classic anaerobic contact process with fully mixed reactor (anaerobic activation process). Circulation is achieved through one or more special mixing devices fitted with guide tubes, which guarantee effective but gentle circulation in the reactor by means of sophisticated hydraulics.

Biomass separation takes place via sedimentation, which is carried out in a special lamella clarifier. The sedimentation unit can either be integrated into the reactor, or installed externally as a separate tank.

This type of reactor is generally employed with wastewater that can be anaerobically treated without major operational problems, but for which the use of granulated sludge is problematic (e.g. sugar- or pulp industry).
