MBBR with the advantages of biofill purification

The key to MBBR lies in the development of biological media with a specific gravity close to that of water, which can easily move freely with the water under slight agitation. Its advantages mainly include the following points:

1.‌Simple Engineering Implementation and Short Startup Period‌

The biofilm formation rate of the biological media in MBBR technology is fast, usually succeeding within about a week, creating conditions for the treatment system to exert its purification effect as soon as possible.‌

2.‌Long Biological Chain and Diverse Biological Species‌

The media provides ample space for the attachment and growth of microorganisms, creating a suitable environment for their growth. This results in a long biological chain, diverse biological species, and high activity.‌

3.‌High Carbon Removal Efficiency and Resistance to Shock Loads‌

MBBR technology exhibits high carbon removal efficiency, enabling the treatment system to achieve high volumetric loading rates. Simultaneously, it has stronger resistance to shock loads and can cope with fluctuations in water quality.‌

4.‌Superior Nitrogen and Phosphorus Removal‌

The biofilm attached to the media favors the growth of aerobic autotrophic bacteria and simultaneously addresses the contradiction of sludge age for nitrogen and phosphorus removal, significantly enhancing the system's nitrogen and phosphorus removal capabilities.‌

5.‌Low Sludge Production‌

Due to the long sludge age of microorganisms on the media, the system produces less sludge, reducing the cost and difficulty of sludge treatment.

6.‌Small Footprint‌

Compared to activated sludge processes, MBBR technology significantly reduces the volume and footprint of structures, making it suitable for areas with limited land resources‌.

7.‌Large Specific Surface Area and High Treatment Efficiency‌

The biological media has a huge specific surface area, providing sufficient attachment space for microorganisms. This significantly increases the biomass per unit volume and thus improves treatment efficiency‌.

8.‌Good Hydrophilicity and High Biological Activity‌

The media incorporates various trace elements that promote the rapid attachment and growth of microorganisms, enhancing its biological affinity. This accelerates the biofilm formation process. Meanwhile, its excellent hydrophilicity and high biological activity ensure stable growth and efficient metabolism of microorganisms on the media surface.‌

In summary, MBBR technology offers multiple advantages in utilizing biological media for purification, including simple engineering implementation, a long biological chain, high treatment efficiency, superior nitrogen and phosphorus removal, low sludge production, and a small footprint. These advantages make MBBR technology have broad application prospects in the field of wastewater treatment‌.‌
