Greenhouse gas emissions from membrane bioreactors: analysis of a two-year survey on different MBR configurations

This study aimed at evaluating the nitrous oxide (N2O) emissions from membrane bioreactors (MBRs) for wastewater treatment. The study investigated the N2O emissions considering multiple influential factors over a two-year period: (i) different MBR based process configurations; (ii) wastewater composition (municipal or industrial); (iii)...

Membrane fouling of AnMBR in hyper saline condition

Membrane fouling problem is one of the most crucial issues which restricts the development of MBR and is, therefore, the prime research topic for many researchers worldwide. Anaerobic MBRs offer interesting perspectives as a potential solution for the treatment of wastewaters under extreme conditions, e.g. high temperature and/or high salt...

Application of high speed imaging as a novel tool to study particle dynamics in tubular membrane systems

Membrane bioreactors represent a promising technology for wastewater treatment, already applied to a wide variety of industrial effluents and sewage. Gas or air sparging is a commonly applied approach to generate surface shear to control fouling phenomena and cake formation causing flux reduction. In inside-out tubular membranes, gas sparging is...
