After the advent of critical flux concept, studies on constant subcritical flux operation of membrane bioreactors (MBRs) gained interest, presumably, because of preferred least fouling operational strategy; however, such a chosen operational condition has demonstrated the continuous slow and irrever

Laboratory bench-scale experiments were conducted to elucidate the effect of ozone on the microfiltration membrane fouling through reaction with particulates in the secondary effluent from BeiXiaoHe WWTP. Membrane resistance (R) was recorded during the filtration course of source water and that afte

Based on an extensive survey of the MBR industry, this article provides an overview of the market interests/ expectations and technical potential of going through a standardisation process of the submerged membrane bioreactor (MBR) technology in Europe. Eighty representative companies and institutio

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

Fouling is still one of the major issues of the membrane bioreactor (MBR) research. Most attention is currently paid to extracellular polymeric substances (EPS) in either bound or soluble/colloidal (soluble microbial products, SMP) form. While several trends or correlations were reported, the compar

The use of a submerged membrane bioreactor for the treatment of industrial oil contaminated wastewater was investigated using microfiltration hollow fibre membranes. The membrane bioreactor worked with a hydrocarbon concentration ranging from 600 to 1500 mg/L in a sub-critical flux regime. The sludg

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

Since the mid nineties the MBR technology has been introduced into municipal wastewater treatment in Europe. First wwtps went in operation performing a conventional mechanical treatment without any advanced mechanical pre-treatment unit. After a short operation period braids were hanging between the

The variation of quality and fouling properties of wwtp effluent over time influences the performance of ultrafiltration (UF) plants. This research reports three experiments in which the specific ultrafiltration resistance (SUR) measurement is applied to obtain more insight in quality variation an i

The paper presents the applicability of a membrane coupled anaerobic baffled reactor (ABR) for low-cost, waterborne sanitation to those communities with limited access to basic sanitation and are inappropriate for on-site, dry sanitation systems. This represents a challenge as anaerobic MBRs must be
