MBBR Bio-Chip for Biological Water Treatment - Quality China Suppliers & Factory Solutions

When selecting the ideal biofilm carrier and determining the necessary quantity, an important criterion is the active surface area. This measurement serves as a reliable indicator of the biodegradation performance of the carrier media. To evaluate the biodegradation efficiency accurately, it is crucial to express performance in terms of kg [pollutant] per m3 [carrier media] per day. This metric facilitates the calculation of the Chemical Oxygen Demand (COD)/Biochemical Oxygen Demand (BOD) or nitrogen load that needs to be treated. Consequently, understanding this specification is vital for calculating the optimal quantity of carrier media required and the associated cost based on biodegradation efficiency per day.

Design and Shape of the Media

,

Choosing the right type and density of material for the carrier media is critical when planning the implementation of your Moving Bed Biofilm Reactor (MBBR) system. In the market, you can find plastic carriers typically manufactured from virgin polyethylene (PE) or more cost-effective re-granulates made from recycled materials. As a leading supplier in China, our factory ensures high-quality production that meets the demands of your wastewater treatment needs.

    Re-granulates

    By their nature, being recycled material, re-granulates contain percentages of different plastics. This can negatively impact the durability of the media and these deficiencies are magnified under operating conditions. The importance of consistent material density cannot be understated, any deficiencies can lead to poor carrier movement characteristics. To account for these inconsistencies manufactures of re-granulate based carrier media often use plasticizers. Plasticizers combined with the re-granulates can release bisphenol A and phthalates which can cause cancer and other hormonal effects. This can be especially problematic for aquaculture and similar industries.

    Virgin polyethylene

    Our MBBR BioChip biofilm carrier is completely free from any phthalates or other plasticizers and does not contain bisphenol A or any other aromatic compounds. It is made of virgin polyethylene (no recycled PE), inorganic fillers, small amounts of monoester of glyceric acid (made from coconut fat; absolutely harmless), citric acid and soda (Na2CO3).

    Stability, wear resistance

    The next consideration is the choice between a dimensionally stable molded (PE or PP) extruded carrier or a mechanically stressable (i.e. flexible) material. Dimensionally stable carriers often possess the disadvantage of breaking even at small mechanical stress levels. Furthermore, they get increasingly abraded which is due to their stiffness being stressed by kinetic energy within the MBBR. Fractures at the bridges of the carriers are hence not unusual as shown below.

    Frequently Asked Questions

    What are the risks of using re-granulate based MBBR carriers?
    Re-granulates (recycled plastics) often lack material consistency, leading to poor carrier movement. To compensate, manufacturers add plasticizers, which can release harmful substances like bisphenol A and phthalates. These compounds are known to cause cancer and hormonal disruptions, posing severe risks, especially in aquaculture.
    What materials are used in your MBBR BioChip?
    Our MBBR BioChip is made from high-quality virgin polyethylene (no recycled PE), inorganic fillers, small amounts of citric acid, soda (Na2CO3), and monoester of glyceric acid (derived from harmless coconut fat). It is completely free from phthalates, bisphenol A, and other aromatic compounds.
    Why is virgin polyethylene superior to recycled PE for biofilm carriers?
    Virgin polyethylene ensures consistent material density, maximum durability, and optimal kinetic movement inside the MBBR tank. Unlike recycled PE, it does not require toxic chemical additives like plasticizers to maintain flexibility, making it completely safe for sensitive biological systems.
    How does the structural stability of the BioChip compare to molded carriers?
    Dimensionally stable molded carriers (PE or PP) are stiff and prone to breaking or abrading under the kinetic stress of an MBBR system. In contrast, our flexible, mechanically stressable BioChip material absorbs kinetic energy without fracturing at the bridges, ensuring long-term wear resistance.
    What is the active surface area of the MBBR BioChip?
    The MBBR BioChip offers a protected active surface area of over 5,500 m²/m³, making it highly efficient for COD/BOD removal, nitrification, denitrification, and ANAMMOX processes.
