These plants are Euromarket’s proprietary designs and are based on an advantage biological treatment process, the Moving Bed Biofilm Process MBBR™(Licensed b AnoxKaldnes AS). The MBBR™ Process is based on the ability to develop aerobic bacteria culture on a protected plastic media surface. The media are kept in suspension by the air that is diffused into the aerobic reactor or with the use of mixing device in case of anoxic denitrification reactors. In turn, the bacteria population biodegrades the organic waste compounds and superior quality effluent is produced. Different models are available with the respect to capacity and treatment configuration.A final collection tank may be used for the storage and disinfection of the purified effluent before this is used for irrigation. This tank does not formed part of the compact unit.

BAK-2 treatment unit can be installed above or partly below the ground. They are totally engineered in EUROMARKET’s factory and are delivered on side for assembly. Their construction is based on the bolted tanks principle. According to the capacity and process configuration of the unit different tank sizes are used. There are available in different to serve 1000 to 20 000 inhabitants.

Practically these units require minimum maintenance, are characterized by very low energy consumption and low excess sludge production. The necessary air blowers and control unit can be installed in a separate cabinet.
BAK-2 treatment units cause no nuisance to the surrounding area due to their low noise emission and odourless operation
