- Side effects of flux enhancing chemicals in membrane bioreactors (MBRs): study on their biological toxicity and their residual fouling propensityV Iversen
Department of Chemical Engineering, University of Technology Berlin, Strasse des 17 Juni 136, MA 5 7, 10623, Berlin, Germany
Water Sci Technol 57:117-23. 2008..OUR tests did not show inhibiting effects for most additives. Chitosan even showed an enhanced OUR due to biodegradability. Oxygen transfer could be enhanced for 25% with the addition of a polymer...
- Impacts of membrane flux enhancers on activated sludge respiration and nutrient removal in MBRsVera Iversen
Technische Universitat Berlin, Strasse des 17 Juni 136, Sekr MA 5 7, 10623 Berlin, Germany
Water Res 43:822-30. 2009..Results show that the changes in kLa values were mostly not significant, however, a decrease of 13% in oxygen transfer was found for sludge treated with PACl...
- Impact of ambient conditions on SMP elimination and rejection in MBRsAnja Drews
Department of Chemical Engineering, Technische Universitat Berlin, Strasse des 17, Juni 136, Sekr MA 5 7, 10623 Berlin, Germany
Water Res 41:3850-8. 2007..Apparently, mainly the nitrite-oxidising community is responsible for the formation for smaller SMP molecules that can pass the membrane...
- Occurrence, source, and fate of dissolved organic matter (DOM) in a pilot-scale membrane bioreactorFangang Meng
Technische Universitat Berlin, 10623 Berlin, Germany
Environ Sci Technol 43:8821-6. 2009..The LC-OCD analysis, together with the results obtained from batch tests, suggested bound EPS might be the most important source of DOM in the sludge suspension...
