MBBR Bio-Chip for Effective Biological Water Treatment – Top China Suppliers and Factory Solutions

When selecting an appropriate biofilm carrier for your Moving Bed Biofilm Reactor (MBBR) system, one critical factor to consider is the active surface area. This measurement is a key determinant of the biodegradation performance of carrier media, which is essential for understanding how effectively pollutants can be removed. To accurately assess biodegradation efficiency, it is vital to calculate the performance in terms of kg [pollutant] per m³ [carrier media] per day. This calculation allows for an effective determination of the COD/BOD or nitrogen load that must be removed, ensuring you can accurately estimate the required quantity of carrier media and associated costs in relation to biodegradation efficiency, **Design and Shape of the Media**, The design and material density of the carrier media are crucial in the successful implementation of your MBBR system. In China, leading suppliers and factories provide a range of plastic carriers typically made from high-quality virgin polyethylene (PE) or more economical re-granulates using recycled materials. Choosing the right supplier from China will ensure that you receive durable and efficient carrier media tailored for optimal biodegradation performance

    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, manufacturers 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

    Why is virgin polyethylene preferred over re-granulates for MBBR carriers?
    Virgin polyethylene offers consistent material density and long-term durability. Re-granulates (recycled plastics) often suffer from inconsistent material qualities and can release harmful substances like bisphenol A and phthalates, which are hazardous to aquatic life.
    Are there toxic plasticizers in the MBBR BioChip?
    No. Our MBBR BioChip is made entirely of virgin PE, inorganic fillers, citric acid, soda, and a small amount of harmless monoester of glyceric acid (derived from coconut fat). It is 100% free from phthalates, bisphenol A, and other aromatic compounds.
    What is the active surface area of the biofilm carrier?
    The protected active surface area is greater than 5,500 m²/m³, which is highly optimized for effective COD/BOD removal, nitrification, denitrification, and ANAMMOX processes.
    How does a flexible carrier compare to a dimensionally stable (stiff) carrier?
    Dimensionally stable (stiff) carriers tend to break easily under mechanical stress and suffer from continuous abrasion due to kinetic movements in the system. Flexible, mechanically stressable materials prevent these structural fractures.
    What are the primary applications of this carrier media?
    It is widely used in high-density indoor aquaculture farms, nursery grounds, ornamental fish culture, seafood temporary maintenance and transportation, as well as various aquarium and fish pond water treatment projects.
