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

When selecting the ideal biofilm carrier for your MBBR system, one of the most crucial criteria is the active surface area. This measure serves as a reliable indicator of the biodegradation performance of the carrier media. It is essential to calculate the biodegradation efficiency in kg [pollutant] per m3 [carrier media] per day, enabling the determination of the COD/BOD or nitrogen load that needs to be removed. Accurately calculating the required quantity of carrier media is vital for understanding the associated costs and ensuring optimal biodegradation efficiency per day.

Design and Shape of the Media

The material type and density of the carrier media play a significant role in the successful implementation of your MBBR system. In China, numerous suppliers offer plastic carriers typically made from virgin polyethylene (PE) or more cost-effective re-granulates (recycled materials). Partnering with a reputable factory ensures you receive high-quality products tailored to your specific needs, enhancing the overall effectiveness of your wastewater treatment process.

Product Detail

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 are the safety risks associated with re-granulate carrier media?

Re-granulates are made from recycled plastics which can contain inconsistent materials. To compensate, manufacturers often add plasticizers. These additives can release harmful substances like bisphenol A and phthalates, which are known to cause cancer and hormonal disruptions, posing risks to sensitive environments like aquaculture.

What materials are used to manufacture the MBBR BioChip biofilm carrier?

The MBBR BioChip is manufactured using high-quality virgin polyethylene, inorganic fillers, and small, harmless amounts of monoester of glyceric acid (derived from coconut fat), citric acid, and soda (Na2CO3).

Does the Virgin Polyethylene BioChip contain harmful chemicals?

No. The virgin polyethylene biofilm carrier is completely free from phthalates, bisphenol A, aromatic compounds, and other toxic plasticizers, making it highly safe for biological water treatment.

Why is flexible carrier material preferred over rigid molded carriers?

Dimensionally stable, rigid molded carriers (made of PE or PP) are prone to breaking under kinetic stress in the MBBR system. They also suffer from severe abrasion due to their stiffness, which often leads to structural fractures at the bridges of the carriers.

What is the active protected surface area of the biofilm carrier?

The carrier provides a highly efficient active protected surface area of more than 5,500 m²/m³, which is ideal for COD/BOD removal, nitrification, denitrification, and ANAMMOX processes.

What are the primary applications of this biofilm carrier?

It is primarily used in factory indoor high-density aquaculture farms, nursery grounds, ornamental fish bases, temporary seafood maintenance/transportation, and various aquarium water treatment projects.
