Mbbr Bio Filter Media for Waste Water Treatment Mbbr Media

No, it is not. With the addition of sucrose and other additives, it is true that the film will be fast, but after a long time, the loss of sucrose will cause the early attached microorganisms to fall off. It will also cause the quality of MBBR carriers to decline, the structure to be unstable, more easily broken, and increased costs. MBBR made of pure HDPE material will last for more than 15 years.

Because the aeration volume of the aerobic tank looks simple, it should actually be just right. If the amount of aeration is insufficient, the nitrification effect will be poor, and the fluidization effect will be poor, and the nitrifying bacteria cannot be fully cultured. However, too much aeration will cause the sludge to swell and fall, resulting in muddy water. Therefore, the specific analysis of specific problems requires the control of aeration for specific problems.

Depending on the situation, if in the anoxic and anaerobic stages, biological mud is unavoidable and must be added. However, in the aerobic tank, if the temperature is moderate, the nitrification effect is good, and it can be omitted. If the number of bacteria is insufficient, an appropriate amount of bio-mud can be added to promote the film-hanging rate.

Using an aerobic tank as an example, if there is biological sludge, the amount of MBBR biological filler is 30%. If there is no biological sludge and the nitrification reaction is performed with pure MBBR material, the added amount can reach 70% or even 80%. Of course, sufficient aeration and agitation are required.

The MBBR process utilizes floating plastic carriers within the aeration tank to increase microorganisms. The media provides increased surface area for attachment and growth. The media is continuously agitated by bubbles from the aeration system that adds oxygen. This provides superior efficiency and value compared to conventional secondary treatment.
