Presentation Transcript

  1. Fagmøte 25.-26. april 2006 Vannforskning i Norge 2006 DEVELOPMENT OF BIOFILM MEMBRANE REACTOR (BF-MBR) Igor Ivanovic, Ph.D student Norwegian University of Science and Technology (NTNU) Department of Hydraulic and Environmental Engineering NO-7491 Trondheim, NORWAY

  2. Content • Membranes in municipal wastewater treatment • Advantages of activated sludge membrane reactor (AS-MBR) • Biofilm Membrane reactor Concept BF-MBR • Comparison AS-MBR vs. BF-MBR • Current activities -POSTER

  3. Conventional AS vs. AS-MBR

  4. AS-MBR benefits  • Membranes are superior to removal organic contaminants and nutrients • Membranes provide a positive barrier to and removal of most pathogens • Membranes can be beneficial for water reuse or recycling applications • HRT is much lower for MBR than for CAS that increasing capacity of plant • MBR plants are much smaller CAS plants and land required for an MBR is about half of that required than CAS

  5. Biofilm process → membrane process PCOD SCOD BIOFILM MEMBRANE REACTOR (BF-MBR) Concept: Investigate the potential of a hybrid MBR process for wastewater treatment based on a moving bed biofilm and a low pressure submerged membrane reactor. Objectives:

  6. AnoxKaldnes+Zenon=BF-MBR concept

  7. Comparison AS-MBR vs. BF-MBR

  8. Current activities • Membrane fouling – more knowledge • Sludge/retentate characteristics (CST,SSV,TTF) • Microscopic assessments (EPS, filamentous structure, influence of OLR on floc structure) • More detailed PSD, fractionation • Assessment of different operational conditions • Aeration rates • Backwashing sequences • Chemically enhanced backwashing • Membrane reactor configurations • Sludge pocket construction • Flocculation

  9. Thanks for your attention!!! Fagmøte 25.-26. april 2006 Igor Ivanovic, Ph.D student Norwegian University of Science and Technology (NTNU) Department of Hydraulic and Environmental Engineering NO-7491 Trondheim, NORWAY
