EPS

Nanofiltration membrane bioreactor (NF-MBR) was proposed to provide quality effluent free of virus and most large organic substances. The dissolved organic matter (DOM) in soluble microbial products (SMP), loosely bound extracellular polymeric substances (LBEPS) and tightly bound extracellular polym

This study is aimed at elucidating the mechanism of the change of molecular weight distribution of EPS by bacterial activities after being attached on the membrane surface and the influence of EPS on the membrane surface on membrane fouling in a laboratory-scale MBR reactor. Change of EPS amount aft

The experimental or theoretical method that can visualize or quantify the architecture of bio-cake formed on the surface of membrane is of great interest in understanding biofouling mechanisms, also controlling biofouling in a membrane bioreactor (MBR). This paper summarizes the methods for determin

The major obstacle for membrane bioreactors (MBRs) to become a widely applicable technology is the membrane fouling. Despite the fact that the fouling is inevitable, understanding of the inherent mechanisms and subsequent integrated modeling of the process seems greatly helpful for optimization and

The extraction and analysis of EPS in active biomass and membrane fouling were performed to investigate the influence of extracellular polymeric substances (EPS) on membrane fouling of MBR. The new membrane and fouling membrane surface morphology was characterized by EDX analysis. The results show t

In biological treatment processes, the effluent contains some portion of organic material originating from soluble microbial products (SMP) that is closely related with extracellular polymeric substances (EPS), although the biological activity is maximized. These SMP should be considered important t

Extracellular polymeric substances (EPS) are considered as the major cause of membrane fouling in membrane bioreactors. Recent studies have revealed a linear relationship between fouling rate (increase of filtration resistance over time) and polysaccharide (PS) concentration [1]. Several factors lik

In this study, hydrodynamics and physiology of microorganisms were investigated in a new type membrane bioreactor, MHCR, which is a membrane coupled HCR (High performance Compact Reactor) having very high COD removal efficiency. The degree of interference caused by inserting a submerged membrane was

The filterability of activated sludge is an important factor for the economical operation of membrane bioreactors (MBR). In the literature mainly investigations on sludge dewaterability in respect to further disposal are published. In this study, a procedure for determining filterability in a crossf
