MBBR Bio-Chip for Effective Biological Water Treatment - China Suppliers and 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
Why is virgin polyethylene superior to re-granulates for MBBR carriers?
Virgin polyethylene ensures consistent material density and outstanding durability. Unlike re-granulates (recycled materials), it does not contain varying percentages of different plastics, which can degrade carrier movement and overall performance under operational stress.
Are there chemical safety risks associated with re-granulated carriers?
Yes. To compensate for material inconsistencies, manufacturers of re-granulate carriers often add plasticizers. These additives can release harmful substances such as bisphenol A (BPA) and phthalates, which are linked to cancer and hormonal disruptions, posing risks to aquaculture environments.
What ingredients are used to manufacture the MBBR BioChip?
The MBBR BioChip is made of virgin polyethylene, inorganic fillers, soda (Na2CO3), citric acid, and small amounts of monoester of glyceric acid (derived from harmless coconut fat). It is completely free from phthalates, plasticizers, BPA, and aromatic compounds.
Why do dimensionally stable molded carriers break easily?
Dimensionally stable molded carriers are rigid, meaning they absorb kinetic energy within the MBBR rather than flexing. This stiffness makes them highly susceptible to abrasion and structural fractures at the carrier bridges under mechanical stress.
What is the active surface area of this biofilm carrier?
The carrier provides a protected active surface area of over 5,500 m²/m³, making it highly efficient for COD/BOD removal, nitrification, denitrification, and the ANAMMOX process.
What are the container loading capacities for shipping?
The carriers are packaged in small 0.1m³ bags. A standard 20ft sea freight container can load 30 m³, while a 40HQ standard sea freight container can load 70 m³.
