MBBR Bio-Chip for Biological Water Treatment - China Suppliers & Factory Solutions
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
Re-granulated media contain varying percentages of different plastics, which negatively impacts durability and movement consistency. Furthermore, manufacturers often add plasticizers that can release harmful substances like bisphenol A and phthalates, known to cause cancer and hormonal imbalances, particularly in aquaculture environments.
The MBBR BioChip is manufactured from high-quality virgin polyethylene (no recycled PE), inorganic fillers, small amounts of monoester of glyceric acid (derived from harmless coconut fat), citric acid, and soda (Na2CO3).
Yes. Unlike re-granulate carriers, the MBBR BioChip is completely free from phthalates, plasticizers, bisphenol A, and other aromatic compounds, making it entirely safe for sensitive environments like aquaculture and ornamental fish farming.
Dimensionally stable molded carriers are stiff and brittle, making them prone to breaking and abrading due to kinetic energy within the MBBR. Mechanically stressable, flexible carriers resist fractures at the structural bridges, ensuring long-term wear resistance and stability.
The MBBR BioChip provides a protected active surface area of over 5,500 m²/m³ for biological processes like COD/BOD removal and nitrification. It has a specific gravity of approximately 0.94 to 0.97 kg/l when clean (without biofilm).
It is packed in small bags containing 0.1 m³ each. For shipping, a standard 20-foot sea freight container can load up to 30 m³, while a 40HQ container can accommodate up to 70 m³ of the carrier media.
