MBBR Bio-Chip for Biological Water Treatment - Top China Suppliers & Factory Solution
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 (FAQ)
What are the risks of using re-granulate (recycled) materials in MBBR media?
Re-granulates often contain inconsistent plastic densities and impurities that reduce durability. To compensate, manufacturers may use plasticizers which can release harmful chemicals like bisphenol A and phthalates, posing serious health risks in aquaculture.
What materials are used to manufacture the virgin polyethylene BioChip?
It is made of 100% virgin polyethylene (no recycled PE), inorganic fillers, soda (Na2CO3), citric acid, and small, completely harmless amounts of monoester of glyceric acid (derived from coconut fat).
Does the virgin PE BioChip contain harmful chemicals?
No. The virgin PE BioChip is completely free from phthalates, bisphenol A (BPA), other plasticizers, or any aromatic compounds, making it entirely safe for sensitive aquaculture environments.
Why is a flexible carrier material better than a dimensionally stable molded carrier?
Dimensionally stable molded carriers (made of rigid PE or PP) are stiff and prone to breaking or abrading under the kinetic stress of an active MBBR system. Flexible, mechanically stressable materials withstand these kinetic forces without fracturing at the structural bridges.
What is the active surface area of this MBBR BioChip?
The active protected surface area is greater than 5,500 m²/m³, which is optimized for highly efficient COD/BOD removal, nitrification, denitrification, and the ANAMMOX process.
What are the primary applications for this MBBR BioChip carrier?
Key applications include high-density indoor factory aquaculture, nursery grounds, ornamental fish bases, temporary seafood maintenance/transportation, and water treatment systems for aquarium projects.
