We started to cooperate with China Academy of science (CAS) in 2001 and successfully developed YULONG MBBR media in 2007.
-- ISBAS® process combines the YULONG Biofilm technology with activated sludge in the same tank.
-- The ISBAS® is not only suitable for municipal wastewater but also each be used for some industrial applications.
-- Excellent Doctor teams could provide 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.,) with MBBR technology
-- The prospect of MBBR process technology has been proved to be quite optimistic because of the characters of saving footprint (The land becomes 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®.

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
