- Flux - (L/m2/hr or GFD)
- Transmembrane Pressure (Bar or PSI)
- Permeability (LMH/Bar or GFD/PSI)
During operation, membrane pores become plugged with inorganics, particulates, and even microbial EPS. While backflushing usually restores the membrane, the loss of flow while backflushing reduces the system charge rate.
For the past year, Aster Bio has been working with an MBR system having issues with biomass EPS reducing flux rates through the membrane. Using both Aster Bio's Microbial Community Analysis (MCA) and customized qPCR based on MCA results, the facility was able to:
- Identify the organisms responsible for problem EPS generation
- Use qPCR testing to monitor the populations and discover impact of operational changes on both "good" and "bad" microbial populations
