Product Details
YULONG MBBR bio media
We started to cooperated with China Academy of science (CAS) in 2001 and successfully developed YULONG MBBR media in 2007.
-- MBBR/ISBAS® (Integrated Suspended Biofilm and Activated Sludge) for A2O,SBR,Oxidation Ditch etc.,
-- ISBAS® process combines the YULONG Biofilm technology and activated sludge in the same tank.
-- The ISBAS® is suitable for municipal wastewater but also be used for some industrial applications.
-- Excellent Doctor teams could provide you reliable technical support and design tailor-made sollution for your actual wastewater project, YULONG has rich experience in doing a lot of successful projects (in pharmaceutical, food industry, etc.,) relying on MBBR technology
-- The future potential of MBBR process technology has been proved to be quite optimistic because of the characters of saving footprint (The land become more expensive because of over development of real estate.) We would like to stand by you to develop more market by using our CORE technology MBBR/ISBAS®.

YULONG MBBR media and ISBAS® use virgin Polyethylene media with high-effective surface areas to grow biofilm.
working for 1 year YL-ll media, biomass:25.56kg/m3
YULONG MBBR media Features:
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 microorganism 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,
MBBR Technology System
ISBAS® Process Technology
ISBAS® Process Benefits
Compact Design; Small footprint; Low investment cost; Easy-to-operate; Stable under large load variations; Saving carbon source; No risk of sludge bulking
Design and Construct Project Cases
Shandong Junan longwang river sewage plant (Daily Treament Capacity: 15000 Cubic Meter/Day)
It was the project of upgrading and retrofitting which started from 2015, had passed the acceptance test in 2016. The original process is A2O+MBBR. We replace the other supplier's MBBR media with YULONG MBBR Media, the retrofitting of MBBR Screen, add Submersible Mixer in anoxic tank and add the Carbon Source in Anoxic Tank, ensure that the effluent quality achieved national 1A discharge standards.
1) User's Requirement
Daily Treament Capacity: Upgrading and retrofitting from 10000 Cubic meter/day to 15000 Cubic meter/day
Efluent Quality:Upgrading and retrofitting from 1B discharge standard to 1A discharge standard.
| Water Quality | COD(mg/L) | BOD(mg/L) | NH4+-N(mg/L) | TN(mg/L) | TP(mg/L) |
| Designed Influent | 500 | 220 | 50 | 55 | 6 |
| Designed Effluent | ≤60 | ≤20 | ≤8(15) | ≤20 | ≤1 |
| Actual Effluent(Average) | 35.18 | 6.85 | 3.51 | 24.97 | 1.48 |
| User's Requirement | ≤50 | ≤10 | ≤5(8) | ≤15 | ≤0.5 |
2) the Water Quality of Upgrading and Retrofitting
The effluent quality achieved national 1A discharge standards. After secondary sedimentation tank, effluent TP is 0.38mg/L, so you can see, removal P can be reached in the biochemical stage. No need chemical phosphorus removal, it will save a lot of money.
| COD(mg/L) | NH4+-N (mg/L) | TN (mg/L) | TP (mg/L) | |
| Influent | 147.28 | 20.95 | 26.75 | 2.35 |
| Effluent | 27.68 | 0.6 | 10.27 | 0.38 |
| Removal Rate | 81.20% | 96.40% | 61.60% | 83.80% |
3) the Biomass of Upgrading and Retrofitting
After upgrading and retrofitting, the biofilm of microorganisms on the surface of aerobic, anaerobic
and anoxic MBBR media were observed.
The biofilm of microorganisms on the surface of anaerobic and anoxic media have abundant dense biofilm. Aerobic media has abundant metazoan. After hanging biofilm matured,the biomass of anaerobic media is 44.11kg/m3,the biomass of anoxic media is 7.37kg/m3,the biomass of aerobic media is 25.26kg/m3.
