Filtration Characterization Method as Tool to Assess Membrane Bioreactor Sludge Filterability—The Delft Experience

Filtration Characterization Method as Tool to Assess Membrane Bioreactor Sludge Filterability—The Delft Experience

Prevention and removal of fouling is often the most energy intensive process in Membrane Bioreactors (MBRs), responsible for 40% to 50% of the total specific energy consumed in submerged MBRs. In the past decade, methods were developed to quantify and qualify fouling, aiming to support optimization in MBR operation. Therefore, there is a need for an evaluation of the lessons learned and how to ...

Comparison and Analysis of Membrane Fouling between Flocculent Sludge Membrane Bioreactor and Granular Sludge Membrane Bioreactor

The goal of this study is to investigate the effect of inoculating granules on reducing membrane fouling. In order to evaluate the differences in performance between flocculent sludge and aerobic granular sludge in membrane reactors (MBRs), two reactors were run in parallel and various parameters related to membrane fouling were measured. The results indicated that specific resistance to the fo...

Characterization of Sludge in a Submerged Membrane Bioreactor

Development of Membrane Bioreactor to Membrane Electro-bioreactor for Advanced Treatment of Wastewater

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

comparing the sludge characteristics in a moving bed membrane bioreactor and conventional membrane bioreactor

the properties of excess sludge wasted from two parallel pilot plants membrane bioreactor (mb-mbr and conventional mbr) have been monitored. sludge samples of mb-mbr and mbr have been examined and compared in terms of vss/tss, filtration index, eps and smp concentration, nitrogen and phosphorous in dry matter, fi, svi and polyelectrolyte requirement for sludge conditioning. by keeping similar o...
