Products and solutions

The Mbbr sewage treatment plant developed by B&P Water Technologies is designed to deliver reliable and efficient wastewater purification across a wide range of applications, even in the presence of high COD (Chemical Oxygen Demand) levels. Based on the proven Moving Bed Biofilm Reactor technology, this system ensures consistent organic load removal while maintaining operational stability and low maintenance requirements.

Unlike conventional solutions, the MBBR process combines the advantages of fixed-film and suspended growth systems. It enables effective BOD5 reduction, nitrification, denitrification and detoxification, offering a robust alternative to traditional activated sludge systems.

Moving Bed Biofilm Reactor Technology

The core of the Mbbr sewage treatment plant lies in the use of biofilm carriers, which provide a large protected surface area for microbial growth. These carriers remain in constant motion within the reaction tank, ensuring optimal contact between biomass, oxygen and wastewater.

Compared to an activated sludge system, the MBBR approach does not rely on sludge recirculation and is inherently more resilient to load variations and toxic shocks. This makes it particularly suitable for installations where influent characteristics may fluctuate over time.

How the MBBR Process Works

The treatment process begins as wastewater enters the reaction tank, where specially designed retention screens ensure that the biofilm carriers remain inside the system. Within this environment, biological degradation takes place through the activity of microorganisms attached to the carrier surfaces.

Air blowers introduce process air into the tank, maintaining continuous mixing and ensuring that the carriers remain in suspension. This movement is essential to maximise oxygen transfer and support efficient biodegradation. The level of dissolved oxygen is continuously regulated by automatic measurement sensors, allowing the system to adapt to changing load conditions without the need for constant operator intervention.

The combined effect of controlled aeration and mobile biofilm results in a highly efficient biological process, capable of achieving stable and high-performance wastewater purification.

Performance and Treatment Efficiency

The Mbbr sewage treatment plant is engineered to meet stringent discharge requirements. Depending on the model and application, it can treat wastewater from 70 to 500 equivalent inhabitants, making it suitable for small communities, industrial facilities and decentralised installations.

Thanks to the use of high-quality biofilm carriers and optimised process control, the system achieves significant pollutant removal, with effluent values reaching COD levels below 100 ppm and BOD5 levels below 20 ppm. These parameters allow the treated water to be safely reused for irrigation or discharged into natural water bodies, including sensitive environments such as coastal areas, without compromising the ecosystem.

Advantages over Conventional Systems

When compared to traditional activated sludge systems or trickling filters, the MBBR configuration offers clear operational and engineering advantages. The absence of a sludge return line simplifies plant design and reduces mechanical complexity, while the lower sludge production translates into reduced handling and disposal costs.

The system’s ability to withstand load variations without continuous operator supervision makes it particularly attractive for remote or decentralised applications. In addition, the compact footprint allows installation in space-constrained environments, without compromising treatment capacity.

Overall, the Mbbr sewage treatment plant combines reliability, ease of use and process stability, making it a long-term, cost-effective solution for wastewater management.

Containerised MBBR Solutions for Easy Deployment

To simplify logistics and installation, B&P Water Technologies offers the Mbbr sewage treatment plant in a containerised configuration. Each system is fully assembled within a container before shipment, ensuring rapid deployment and minimal on-site assembly.

This approach is particularly advantageous for international projects, where transport efficiency and installation speed are critical factors. The containerised solution reduces potential delays, minimises civil works, and allows the plant to be operational in a significantly shorter timeframe.
