MBBR Technology and Biofilm Carries
MBBR technology is based on the biofilm principle with an active
biofilm growing on small specially designed plastic carriers that
are kept suspended in the reactor. The technology utilizes the
advantages of both activated sludge and other biofilm systems (e.g.
biofilters, biorotors etc.) without being restrained by their
disadvantages.
The carriers are designed to provide a large protected surface area
for the biofilm and optimal conditions for the bacteria culture
when the carriers are suspended in water.

Advantages:
1. Super decarburization, ammonia nitrogen removal capacity
Carrier provide a safe and comfortable environment for microbial breeding, Biological variety, because of no sludge age limit, nitrifying bacteria have also been large-scale breeding, microbial population huge is dissolved organic compounds and ammonia decomposition.
2. Excellent resistance to shock load performance
Efficient processing capacity, its ability to remove organic matter 2-5 times higher than that of other traditional methods, high concentrations of biomass and diversity of biological fungus, strong resistance to impact load capacity
3. Flexible way of engineering application
Different stages can be applied to the good nitrogen, anaerobic, anoxic process, only need to handle effect by adding the filter media can easily obtain satisfactory result.
4. Simple operation and maintenance
Without support, put filter media in the pool directly, and it can save the return sludge, avoiding sludge bulking, come-up and loss, convenient to operate and maintain.
5. Long service life
Through a special process modification, the filter media have a good resistance, UV resistance, strong toughness, not easy to aging and embrittlement, and it has a long service life.
Question:
Why did others hang the film faster after adding sucrose, is the pure HDPE material already eliminated?
Answer: 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.
