Wastewater treatment with modern MBBR technology!
In our factory in Hungary, we manufacture moving bed biological filter media (MBBR). Our product is made of certified EU-certified raw materials and has an increased biofilm support surface based on a uniquely designed profile. We undertake the production and on-site delivery of MBBR media, from small individual requests to quantities serving the needs of communal industrial facilities.

About of MBBR technology
Moving bed biofilm reactor (MBBR) is a biological technology used for wastewater treatment process suitable for municipal and industrial application (residential wastewater treatment, recirculating aquaculture system-RAS). MBBR offer an economical solution for wastewater treatment. MBBR wastewater treatment system enables efficient results of the disposal using low energy. The technology is used to separate organic substances, nitrification and denitrification. MBBR design is made of an activated sludge aeration system. The sludge is collected on the plastic carriers which have a large external and internal surface area. The surface area in the carriers optimizes the contact of water, oxigen of the air, and the bacterial layer.
MBBR is applicable to the different quality of wastewater treatment. The MBBR system can be of more than one stage depending on specific needs. The stages are made of individual tanks separated by screens to ensure that bacteria remain in their specific tank.:
- Aeration tank: The tank is similar to an activated sludge tank. The aeration is used to keep in motion the activated sludge and carriers and supplies the biofilm layer with oxygen. The MBBR system separates the excess bacteria and sludge which are directed to the final separator (ex. drumfilter).
- Plastic carriers or MBBR bio ball provide a surface for biofilm growth. Carrier materials are made of materials with a density close to that of water high-density polyethylene (HDPE) with a density of 0.98 g/cm³. The MBBR biofilter provides a surface area of 950 m²/m³ and weighs 115 kg/m³. These carriers are moved in the tank through the aeration system and adequate water flow. This ensures good contact between the wastewater and the biomass on the carriers.
Benefits of MBBR technology
- Saving of space due to its compactness.
- Easy to maintain.
- Good for a high volume of biological load.
- Extension and expanding are easy. This made possible by increasing the filling degree of MBBR bioball.
- Lower discharge costs.
- Independent process performance because there is no return line for sludge; the MBBR eliminates the return activated sludge (RAS).
- It has high effectiveness of sludge retention time (SRT) which enhances the nitrification process.
- Production of sludge is lower.
- It does not need recycling of the sludge-like activated sludge system.
- MBBR media is installed to retrofit existing activated sludge tanks in order to increase its capacity.
Application of MBBR
- Biological Oxygen Demand (BOD) removal - It requires only one wastewater tank with the MBBR and clarification.
- Nitrification - It uses two tanks one for BOD removal and the other for nitrification.
- Denitrification - It uses four aeration tanks in this order before emptying in the clarification with pre denitrification, BOD reduction, nitrification and post denitrification.
MBBR technology is applicable in industries, for municipal wastewater treatment.
Operation and maintenance of MBBR
MBBR which is in constant use does not require backwashing or return sludge flows. Wastewater treatment tank operation is at low cost because of the coarse-bubble aeration in the aeration zone. The agitation constantly moves the carriers over the service eliminating clogging.
Maintenance of the MBBR system is mainly done in the form of screening, sludge handling, influent equalization and it also involve maintaining the integrated control system and clarifier system. MBBR technology has a self-maintenance mechanism.
MBBR technology is effective for wastewater treatment if the regulation concerning the effluent water discharge. The system is flexible in its application and can easily be relocated. The good quality wastewater treatment as required for ecological reasons can be done using the MBBR.
