MBBR Bio-Chip for Effective 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
Why is virgin polyethylene preferred over re-granulates for MBBR BioChip?
Re-granulates contain varying percentages of different plastics, which compromises material durability and consistency. This can lead to poor carrier movement characteristics. Additionally, re-granulate carriers often contain plasticizers that may release harmful chemicals like bisphenol A and phthalates.
Does the MBBR BioChip contain any harmful plasticizers?
No. Our MBBR BioChip is completely free from phthalates, bisphenol A, and other aromatic compounds. It is manufactured using only virgin polyethylene, inorganic fillers, and harmless food-grade additives such as citric acid, soda, and monoester of glyceric acid.
What is the active protected surface area of the biofilm carrier?
The active protected surface area is greater than 5,500 m²/m³, which is highly optimized for COD/BOD removal, nitrification, denitrification, and ANAMMOX processes.
How does the flexibility of the carrier prevent damage?
Unlike rigid molded carriers (PE or PP) that are prone to fracturing under mechanical stress and kinetic energy in the MBBR system, our flexible, mechanically stressable material prevents fractures and minimizes abrasion.
What are the main applications for this product?
It is widely used in factory indoor aquaculture farms (especially high-density systems), nursery grounds, ornamental fish bases, seafood temporary maintenance and transport, and various aquarium water treatment projects.
