A laboratory scale external anaerobic dynamic membrane bioreactor (AnDMBR) treating high strength wastewater was operated to assess the effect of gas sparging velocity and organic loading rate on removal efficiency and dynamic membrane (DM) filtration characteristics. An increase in gas sparging velocity (GSV) results in a decrease in DM filtration resistance. DM or cake formation was identifie...

With the current focus on water reuse projects and the role they play in the water cycle, the search for cost competitive advanced wastewater treatment technologies has never before been so important. Australia in particular has a need to develop new strategies for water management and will continue to move towards water reuse where such projects are shown to be financially viable. This paper d...

With increasing water reuse applications and possible stringent regulations of phosphorus content in secondary and tertiary effluent discharge in Florida, USA, alternative technologies beyond conventional treatment processes require implementation to achieve low phosphorus (P) and nitrogen (N) concentrations. A pilot scale membrane bioreactor (MBR) system, operated in Florida, adopted the Unive...

A membrane-coupled aerobic bioreactor (MBR) can be described as a system coupling the aerobic bioreactor, or activated sludge tank, of a wastewater treatment system with a microor ultrafiltration membrane. The membrane serves to separate the suspended material in the sludge so that the permeate stream is free of chemicals, microorganisms, and other contaminants. The membrane may be either inter...

Abstract Recent advances in wastewater treatment processes have resulted high removal efficiencies for various hazardous pollutants. Nevertheless, some technologies are more suitable targeting specific contaminants than others. We comprehensively reviewed the recent removing pollutants from industrial through membrane technologies, adsorption, Fenton-based processes, advanced oxidation (AOP), a...

Background & Aims of the Study: In order to design membrane bioreactors (MBR) properly, it is essential to comprehend the behavior of microorganisms in such wastewater treatment processes. Materials & Methods: In this study, a lab-scale MBR process was operated to determine the biokinetic coefficients of the MBR system under different MLSS concentrations of 6800, 7000, 74...

Soluble microbial products (SMP) have been long time considered the major cause of membrane fouling when membrane bioreactors (MBR) are used for wastewater treatment. As a result, the formation and degradation of SMP have been incorporated in the conventional ASM models for a better prediction of MBR performance. This paper studies the impact of SMP modelling when optimizing the start-up of an ...
