MBR

The comparative study was conducted to investigate the performance and removal efficiencies of PFOS and PFOA in MBR and PAC-MBR. Solid phase extraction (SPE) followed by HPLC coupled with tandem MS (HPLC/MS/MS) was applied to quantitatively identify PFOS and PFOA in aqueous and sludge samples. Remova

This paper quantifies the influence of operating conditions on the efficiency of domestic wastewater treatment and of membrane bioreactors (MBR) performance with a statistical method (multivariate linear regression model). The impact of the following seven parameters—(1) transmembrane pressure (TMP)

An anaerobic thermophilic submerged membrane bioreactor was operated for 300 days, with a mixture of volatile fatty acids as substrate. Cake formation was identified as the key factor governing critical flux. Low levels of irreversible fouling were observed. During the first 60 days of operation a r

In this study, the hydrodynamics of a pilot scale membrane bioreactor (MBR) with different configurations for air scouring were investigated experimentally and numerically. The results were analyzed with the aim to derive a correlation between the aeration flow rate and the circulation velocity in t

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 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

Water shortage has become a global issue and not only a problem relevant to arid zones. In the past decade desalination of sea and brackish water has been found to be a technically and economically acceptable solution for water shortage. More recently, desalination of wastewater effluents has also b

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
