YULONG® MBBR bio media
-- MBBR/ISBAS™(Integrated Suspended Biofilm and Activated Sludge)
-- ISBAS™ process combines the YULONG® Biofilm technology and activated sludge in the same tank.
We started to cooperated with China Academy of science (CAS) in 2001 and successfully developed YULONG® MBBR bio media in 2007.
-- The ISBAS™ is especialy suitable for municipal wastewater but also be used for some industrial applications.
-- We design, professional manufacture and after-sales service of our products in China,
-- Excellent Doctor teams could provide you reliable technical support and devise tailor-made sollution for your actual wastewater project.
-- We have rich experience in doing a lot of successful projects (in pharmaceutical, food industry, etc.,) relying on MBBR technology

Working for 1 year YL-ll Oxic media, biomass:6kg/m3
1) Bioflim forming time is 3~15 days, the fastest is only 2 days. Do not culture of bacteria in advance. The formula scientific substance support the growth of heterotrophic and autotrophic bacteria within its cells
2) Special Surface Treatment
- Larger and Roughness Inner Surface to Enhance Microble cell Adhension and Biofilm Forming Rapidly
3) Good Hydrophilicity
- Add Hydrophilic Groups to Improves Biofilm Formation and Biomass
4)The surface of our MBBR media is with positive Charge which promote Microorganism Growth , the study report most of microorganisms take negative charge.
5)Biomass (g/m2) 10 - 20
6)High efficience removal of BOD5,COD, TSS etc,
Mainly manufacturing medicines like vitamin, antibiotics and rifamycin. Sewage from this plant is very hard to be treated for its quite complex composition and more than 4% salinity. Upgrading and reconstruction by using YULONG media, and processing capacity more than doubled.
| Water yield | Process | COD(mg/L) | COD Load (Kg/(m3.d)) | Ammonia Nitrogen (mg/L) | |
| inflow | | | 10000~15000 | | 200~400 |
| Before Remould(effluent) | 1000t/d | Activated Sludge Process | 600~1000 | 1 | 300~500 |
| After Remould(effluent) | 2000t/d | MBBR Process | <1000 | >2 | 200~300 |
Which produce Vitamin C, the influent quality is complex, the chloridion concentration reached 12000mg/L which is difficult to deal with. Reconstruction goal have been reached and up to the let off standard after finishing the project by using the YULONG media.
| Process | | COD | HRT |
| Inflow(mg/L) | 2000~3000 | ||
| Contact Aeration Basin | Effluent(mg/L) | >1000 | 24h |
| Load(Kg/(m3.d)) | 1.5~2 | ||
| MBBR Process | Effluent(mg/L) | <500 | 8~10h |
| Load(Kg/(m3.d)) | 4~6 |
Roughness with fins is well proven to enhance microble cell adhension and the effective specific surface immensely.
We can see the below two picuters comparison from naked eye , obviously YULONG MBBR bio media is more rough than the other supplier.
2. Zata-potential
In most cases, microbles are with negative charges, after a special surface treatment in YULONG MBBR bio media which is with positive charges, hence it will enhance bio-film forming rapidly.
3. Hydrophilicity affect
Microbles is Hydrophilic particles, hydrophilicity of YULONG is also very suitable for microbial growth.
4. Fluidization
The specific gravity of YULONG MBBR media is between 0.97~1.05 that make the media filter fluidization under less power consumption.
Void ratio of YULONG MBBR bio media can reach 90%, the configuration of YULONG MBBR bio media is designed into honeycomb, scientific size is more suitable for 3-D flow of media filter. YULONG MBBR bio media can touch the pollutant easily.
