Effectiveness of hydrophobic vs. hydrophilic MBBR media

 In Moving Bed Biofilm Reactor (MBBR) technology, the choice of media plays a crucial role in the performance and effectiveness of the system. Among them, hydrophobic and hydrophilic media are two common choices, which have significant differences in biofilm formation, attachment and wastewater treatment effectiveness. This paper will compare the effectiveness of hydrophobic and hydrophilic MBBR media in wastewater treatment.

Hydrophobic MBBR media:

Surface Characteristics: The surface of hydrophobic MBBR Machine usually has a high contact angle, and water droplets on its surface show a high contact angle and are difficult to wet.

Bio-adhesion: Because the surface is not easy to wet, the bio-adhesion ability of hydrophobic MBBR media is weak, and the formation of biofilm is relatively slow.

Wastewater treatment effect: Hydrophobic MBBR media usually show low degradation efficiency in wastewater treatment, especially for easily hydrolysed organic substances.

Hydrophilic MBBR media:

Surface properties: The surface of hydrophilic MBBR media usually has a low contact angle, and water droplets present a low contact angle on the surface, which is easy to wet.

Bio-adhesion: Because the surface is easy to be wetted, hydrophilic MBBR media has a strong bio-adhesion ability and the biofilm formation is relatively fast.

Wastewater treatment effect: Hydrophilic MBBR Filter Media usually show higher degradation efficiency in wastewater treatment, and can degrade organic substances and pollutants in wastewater more effectively.

Comparative analysis:

Bio-attachment rate: The bio-attachment rate of hydrophilic MBBR media is significantly higher than that of hydrophobic MBBR media.

Degradation efficiency: Hydrophilic MBBR Bio Media generally have higher wastewater treatment efficiency due to rapid biofilm formation and attachment.

Stability: The biofilm of hydrophilic MBBR media is relatively stable and not easily affected by external factors.

Conclusion:

  Hydrophobic and hydrophilic Bio Media MBBR have their own characteristics and are suitable for different wastewater treatment needs. The selection of media should be based on the nature of wastewater, treatment effect and cost. However, in general, hydrophilic MBBR media are more effective in wastewater treatment, with higher bioattachment rates and higher wastewater treatment efficiencies, and are therefore preferred in many application scenarios.
