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

When selecting the right biofilm carrier for your Moving Bed Biofilm Reactor (MBBR) system, one of the most important criteria to consider is the active surface area. This metric is crucial as it serves as a reliable indicator of the biodegradation performance of the carrier media. To accurately assess this performance, it's essential to calculate the biodegradation capacity in kg [pollutant] per m3 [carrier media] per day. This calculation enables you to determine the chemical oxygen demand (COD)/biological oxygen demand (BOD) or nitrogen load that needs to be removed. By using this method, you can effectively estimate the required quantity of carrier media and understand the associated costs related to biodegradation efficiency on a daily basis.

    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 is the main risk of using re-granulate based MBBR carriers?
    Re-granulate carriers are made from recycled plastics which often have inconsistent material densities. To resolve this, manufacturers add plasticizers that can release harmful chemicals like bisphenol A and phthalates. These compounds can cause cancer and disrupt hormones, posing a serious threat to aquaculture.
    Why is virgin polyethylene better for aquaculture applications?
    Virgin polyethylene contains no recycled plastics and is completely free from harmful plasticizers, phthalates, bisphenol A, and other aromatic compounds. This ensures a non-toxic environment, which is vital for sensitive species in aquaculture and ornamental fish farming.
    How does carrier flexibility affect its lifespan in an MBBR tank?
    Stiff, dimensionally stable carriers (like molded PE or PP) are prone to breaking under the kinetic stress of MBBR systems. Mechanically stressable, flexible materials absorb this energy and resist abrasion, preventing fractures at the carrier's structural bridges.
    What is the active surface area of the Virgin PE BioChip?
    The protected active surface area of the carrier is greater than 5,500 m²/m³, making it highly efficient for biological processes such as COD/BOD removal, nitrification, denitrification, and ANAMMOX.
    Where can the MBBR BioChip carrier be applied?
    It is ideal for factory indoor high-density aquaculture farms, aquaculture nursery grounds, ornamental fish bases, seafood temporary maintenance/transportation, and water treatment systems for public aquariums and fish ponds.
