Discover our comprehensive range of CE-certified equipment, from precision lifting mechanisms to heavy-duty wastewater purification solutions.
In an era defined by intensifying water scarcity, strict environmental regulations, and urban sprawl, traditional activated sludge methods are hitting clear limits. The Moving Bed Biofilm Reactor (MBBR) has emerged as a key technology for modern industrial and domestic sewage treatment. By using floating carrier media with high specific surface areas, MBBR merges the benefits of suspended growth (activated sludge) and attached growth (fixed-film) systems.
As a leading integrated engineering provider, Qingdao Cherish designs and manufactures advanced, containerized, and built-to-order wastewater systems. With CE certification, our MBBR packages comply with EU safety, health, and environmental standards, making them highly reliable options for developers, municipalities, and industrial facilities globally.
Whether handling high-strength chemical wastewater or municipal sewage, our systems ensure low retention times, minimal sludge footprint, and consistent biological nitrogen and phosphorus removal.

MBBR plants pack high biological activity into a compact volume. The space-saving design is perfect for decentralized municipal plants, resorts, or industrial factories with limited space.
The specialized biofilm on the carrier elements naturally adapts to fluctuations in influent chemistry and flow rates, providing stable effluent quality even during peak hours.
Designed for plug-and-play installation, our containerized MBBR units require minimal daily maintenance. Smart monitoring systems track dissolved oxygen (DO) and levels automatically.
Moving Bed Biofilm Reactor (MBBR) technology works by introducing small, engineered plastic carrier elements into the aerated wastewater basin. These carriers have a density close to that of water, allowing them to remain suspended and move freely throughout the reactor. The fluidization is maintained either through aeration in aerobic systems or by mechanical mixers in anoxic systems.
Our MBBR plants utilize high-density polyethylene (HDPE) carriers characterized by a high effective surface area (typically >800 to 1200 m²/m³). Over time, a robust microfilm of specialized bacteria develops on the inner protected surfaces of the carriers. This biofilm breaks down dissolved organic contaminants. Because the active biomass is secured on these floating carriers, the system is less prone to biomass washout compared to conventional activated sludge setups.
A standard Cherish integrated MBBR system is divided into functional zones to achieve complete nutrient removal:
The global wastewater treatment market is shifting rapidly toward decentralized solutions. Building large-scale centralized treatment plants requires extensive sewer networks and high capital investment. Integrated, containerized MBBR units offer a flexible alternative. In North America and Western Europe, stricter regulatory limits on Total Nitrogen (TN) and Phosphorus (TP) are driving facilities to upgrade existing plants by adding MBBR media directly into aeration basins, boosting capacity without expanding concrete footprints.
In developing regions across Asia and Latin America, decentralized MBBR systems are increasingly used to treat municipal waste in new master-planned communities, commercial parks, and rural developments.
Qingdao Cherish specializes in integrating biological MBBR reactors with pre-treatment and post-polishing processes. In heavy industrial settings like chemical manufacturing or textile finishing, we combine MBBR systems with Reverse Osmosis (RO) and advanced filtration to achieve Zero Liquid Discharge (ZLD) and water reuse. This closed-loop approach helps industrial facilities meet water conservation mandates while lowering operational costs.

Operating in diverse geographical climates requires highly engineered adaptations to standard biological systems. Temperature fluctuations directly impact biological kinetic rates, requiring custom designs for different regions:
In colder regions, biological nitrification speeds decrease. To maintain stable treatment performance without building larger tanks, our systems utilize insulated container housings, heat exchangers, and increased carrier filling ratios (up to 65%). This approach keeps the biomass active, ensuring effluent quality remains compliant even during winter.
Saline wastewater can inhibit standard microorganisms. We address this by seeding the MBBR carriers with salt-tolerant bacterial strains (halophilic cultures). The attached biofilm provides a protected micro-environment that shields these specialized bacteria from osmotic shock, offering reliable treatment where conventional systems often struggle.
Resorts experience high seasonal variation in wastewater flow. Standard activated sludge systems can struggle with washout during low seasons. In contrast, MBBR plants maintain stable biological films on carriers during quiet periods, allowing the system to handle sudden increases in visitor numbers without performance drops.
Expert insights on MBBR design, operations, maintenance, and international compliance standards.
CE Certification verifies that the equipment meets EU safety, health, and environmental protection standards. For municipal and industrial projects, this certificate ensures compliance and simplifies the permitting process in Europe and other regions aligning with European directives.
Our HDPE carrier media are engineered for durability, typical offering a design life exceeding 20 years. Unlike sand filters or membrane systems, they do not require regular backwashing or chemical cleaning, significantly lowering long-term operating costs.
Yes. Retrofitting existing aeration basins with carrier media (known as an Integrated Fixed-film Activated Sludge, or IFAS upgrade) is a common way to increase capacity and improve nutrient removal without building new tanks.
We install stainless steel retention screens at the outlet of each reactor stage. These screens allow wastewater to flow through while keeping the carriers inside the basin. The opening sizes are selected based on the specific dimensions of the carrier media.
The filling ratio generally ranges from 30% to 67% of the empty tank volume. The specific ratio is calculated based on organic load, wastewater characteristics, temperature, and effluent requirements to ensure optimal mixing and kinetics.
Nitrification requires sufficient oxygen levels. We maintain DO concentrations between 2.0 and 4.0 mg/L in the aerobic zones. Automated blower controls adjust airflow in response to real-time DO readings to save energy.
Effective pre-treatment is important to protect the media. Fine screening (typically 1-2 mm) is required to remove hair, plastics, and large solids that could clog the screens or accumulate on the carriers.
Yes, biological activity decreases in cold temperatures. For installations in cold climates, we adjust the carrier filling ratio and size the tanks to maintain target effluent standards during winter.
