MBBR - Combiblock Units

PREFABRICATED COMBIBLOCK sewage treatment plants are compact, factory-assembled units designed to treat wastewater generated by a number of houses, residential blocks or small communities.Their unique characteristic is that their external dimensions are equivalent to ISO standard containers (same height and width) making these units easy to transport, install and relocate.

COMBIBLOCK units are proprietary designs of Euromarket and are based on an advanced biological treatment process, the Moving Bed Biofilm Process MBBR. The MBBR process is based on the development of an aerobic bacteria culture on a protected plastic media surface. The media are kept in suspension by air that is diffused into an aerobic reactor or with the use of mixing devices in the case of anoxic denitrification reactors. In turn, the bacteria population biodegrades the organic waste compounds and an effluent of superior quality is produced.

Different COMIBLOCK models are offered with respect to capacity and treatment configuration. A separate pretreatment unit for FOG removal, primary sedimentation, balancing and aerobic Sludge digestion is normally installed prior to the main COMBIBLOCK unit. This pretreatment unit may be custom made of concrete, or of stainless steel as a prefabricates structure.

In the container-like MBBR unit a number of processes are performed: Two-stage BOD5 removal, Nitrification (optional), Denitrification (Optional) and Sedimentation (gravity or via a lamella plate settler). The mono-block construction also houses the control cabinet with the air Blowers, control unit, and dosing stations for chlorine and coagulant/flocculant when required. A final collection tank may be used for the storage and disinfection of the purified effluent before discharge. This collection tank does not form part of the compact unit.

The COBIBLOCK effluent can either have secondary (BOD5 < 20 mg/l and SS < 30mg/l) or tertiary (BOD5 < 10 mg/l and SS < 10mg/l) quality characteristics. The tertiary quality can be achieved without filtration, simply with the addition of flocculating and coagulating agents to the effluent prior to the sedimentation stage. COMBIBLOCK treatment units can be installed above or below ground. They are available in seven different sizes ranging from 300 to 1500 PE depending on the treatment configuration. Tailor made designs are also possible to much specific effluent requirements or for the biological treatment of industrial wastewater. COMBIBLOCK units required minimum maintenance and are characterized by very low energy consumption. They cause no nuisance to the surrounding area due to their low noise emission and odourless operation.
