AS-MBBR05

• Large surface area: AS-MBBR05 features a surface area of 1000 ㎡/m³. This provides ample space for microbial attachment, enabling the colonization of more microorganisms. It can be effectively used in sewage treatment scenarios, contributing to enhanced treatment efficiency.
• Suitable for related biological processes: With an inside void size of 5 - 6 mm and a diameterheight of 117 mm, and 980K units per m³, it creates a favorable micro - environment. It is adaptable for biological treatment processes like nitrification, where the attached microbes can participate in the relevant biochemical reactions.
• Practical application performance: The combination of its structural parameters (size, void, quantity per unit volume) allows it to play a role in sewage treatment systems. Whether in small - scale sewage treatment facilities or as part of a larger - scale wastewater treatment process, it can support the growth and metabolism of microbial communities, helping to purify sewage through microbial actions.

AS-MBBR19

• Suitable for general sewage treatment: AS-MBBR19 filler is the most classic and widely used filler in MBBR process, suitable for municipal sewage and industrial wastewater treatment.
• Moderate surface area (>650 m²/m³): It provides better biological attachment space, which is conducive to microbial growth and sewage treatment efficiency.
• Strong fluidity: AS-MBBR19 filler has a larger pore size and is lightweight. So it is easy to flow in the reactor for higher efficiency of biofilm renewal.
• Good impact load resistance: It can cope with water quality fluctuations, to be particularly suitable for occasions with large changes in sewage volume.

AS-MBBR37

• Moderate surface area (>800 m²/m³): It has a larger biological attachment area. This makes it suitable for high - load sewage treatment, to improve the removal rate of ammonia nitrogen and organic matter.
• Suitable for deep denitrification: Due to its large surface area, AS-MBBR37 filler is more suitable for nitrification processes and the ones that require efficient denitrification (such as BAF, AAO processes).
• More complex structure: The geometric design of AS-MBBR37 filler is more complex than that of AS-MBBR04 filler. It enhances microbial attachment and suits better for low temperature or low load environments.
• Suitable for high-load industrial wastewater: Due to its stronger biofilm carrying capacity, AS-MBBR37 filler performs well in the treatment of high-concentration organic wastewater like: food processing, aquaculture, and pharmaceuticals.

AS-MBBR78

• Larger surface area: AS-MBBR78 filler has a larger biological attachment surface, so it can support the attachment of more microorganisms. It is used mostly in high-concentration sewage, with improved treatment effect.
• Suitable for deep denitrification: Due to its large surface area, AS-MBBR78 is particularly suitable for processes such as nitrification and denitrification. It is especially suitable for the ones that requires deep denitrification, like BAF and AAO.
• Structural complexity: The geometric design of AS-MBBR78 filler is more complex, with enhanced attachment ability of microorganisms. It is particularly suitable for sewage treatment with heavy loads, to optimize the growth and reproduction of microbial populations.
• Suitable for industrial wastewater treatment: AS-MBBR78 filler has a strong load-bearing capacity, which is particularly suitable for high-concentration industrial wastewater treatment. It can effectively improve treatment efficiency, and is widely used in industries such as petrochemicals, steel, and pharmaceuticals.

AS-MBBR92

• Improved mass transfer efficiency: More holes can intensify the turbulence of water flow in the reactor, promote the full contact between sewage and biofilm, and facilitate the transfer of organic matter, ammonia nitrogen and other substrates from the water body to the surface of the biofilm. At the same time, it is conducive to the discharge of gases such as carbon dioxide and nitrogen produced by microbial metabolism, effectively improving the treatment efficiency of the reactor.
• Promotion of microbial growth and attachment: The rich pore structure provides more attachment sites for microorganisms, increases the specific surface area of the biofilm, and is suitable for the growth and reproduction of various microorganisms such as aerobic bacteria, anaerobic bacteria, and facultative bacteria, forming a complex and diverse microbial community, and enhancing the removal ability of different pollutants.
• Enhanced system stability: The 92 holes are evenly distributed, making the water flow more evenly distributed in the reactor, avoiding water short circuit or dead zone, reducing the impact of water quality and hydraulic shock, and improving the stability and reliability of MBBR system operation.
• Optimization of hydraulic conditions: The reasonable number of holes and pore size design can regulate the hydraulic retention time and characteristics in the reactor, optimize the flow state of sewage, improve the treatment effect, reduce sludge loss, and ensure the stability of effluent water quality.
