“…It has been reported that SMP are complex and play an important role in membrane fouling (Meng et al, 2009). However, it is not clear that which types of proteins and polysaccharides were the main foulants and whether the GAC influences their existence in anaerobic reactors.…”

h i g h l i g h t sAdding GAC alleviated membrane fouling of a membrane-coupled EGSB process. It reduced the concentrations of SMP, SMP ps and SMP pr by 26.8%, 27.8% and 24.7%. It primarily reduced tryptophan proteins, aromatic proteins and fulvic substances. GAC addition mainly decreased the cake layer resistance proportion by 53.5%. a r t i c l e i n f o b s t r a c tTo mitigate membrane fouling of membrane-coupled anaerobic process, granular activated carbon (GAC: 50 g/L) was added into an expanded granular sludge bed (EGSB). A short-term ultrafiltration test was investigated for analyzing membrane fouling potential and underlying fouling mechanisms. The results showed that adding GAC into the EGSB not only improved the COD removal efficiency, but also alleviated membrane fouling efficiently because GAC could help to reduce soluble microbial products, polysaccharides and proteins by 26.8%, 27.8% and 24.7%, respectively, compared with the control system. Furthermore, excitation emission matrix (EEM) fluorescence spectroscopy analysis revealed that GAC addition mainly reduced tryptophan protein-like, aromatic protein-like and fulvic-like substances. In addition, the resistance distribution analysis demonstrated that adding GAC primarily decreased the cake layer resistance by 53.5%. The classic filtration mode analysis showed that cake filtration was the major fouling mechanism for membrane-coupled EGSB process regardless of the GAC addition.

“…Although AnMBR has advantages such as high removal efficiency of organic matters and small footprint, etc., there are still some challenging issues. Particularly, membrane fouling is the key challenge for the widespread applications of AnMBR (Guo et al, 2012;Meng et al, 2009).…”

“…It is also important that in comparison to the conventional activated sludge method the use of a secondary clarifier can be omitted, and thereby the footprint of the treatment system can be reduced. It is also possible to maintain high concentration of sludge in the membrane bioreactor, which corresponds to increased capacity of a treatment system [12][13][14][15][16][17][18][19].…”

Abstract:The aim of presented study which was associated with modification of the various work cycle phases duration in the membrane bioreactor, was to reduce the concentration of phosphate phosphorus during the leachate co-treatment with dairy wastewater. The experimental set-up was comprised of the membrane bioreactor equipped with the immersed membrane module installed inside the reactor chamber, and the equalization tank. During the co-treatment experiment performance the excessive activated sludge was constantly removed from the membrane bioreactor in order to keep its concentration at 3.5 g/dm 3 . The load of the sludge with the contaminants was equal to 0.06 g COD/g d.m. d. The concentration of oxygen was equal to 3 mg/dm 3 . The share of the leachates in the co-treated mixture was equal to 10% vol. The membrane bioreactor worked as the sequential biological reactor, in two cycles per day. Duration of each phase was equal as follows: filling -10 min -with concurrent mixing phase lasting for 4 h, aeration phase -1 h, sedimentation -30 min and removal from purified wastewater -30 min. After 4 weeks under these conditions, the modification of the sequential membrane bioreactor's work cycle was made. The duration of particular phases was shortened and two phases of denitrification and nitrification were introduced. Work cycle phases were modified as follows: filling -10 min -with concurrent mixing phase lasting for 3 h, aeration phase -4 h, mixing phase -1 h, aeration phase -3 h, sedimentation -30 min and removal from purified wastewater -30 min. Based on research, it was found that the change in membrane bioreactors' work cycle affects the effectiveness of treated mixture. It was found that the applied modification of phases of the cycle of the MSBR did not affect the concentration of organic compounds and the no significant changes in the concentration of ammonium and nitrate nitrogen in the effluent from the bioreactor were observed, however, the total nitrogen removal efficiency increased by 50%. Alteration of MSBR reactor particular phases duration caused reduction of concentration of P-PO4 3 from 4.7 to 2.9 mg/dm 3 .

“…However, its widespread application is still restricted by a membrane fouling phenomenon, which lowers the applied flux, reduces the sustainability of operation, increases the frequency of maintenance and intensive cleaning, reduces the membrane lifetime, and eventually increases the investment and operational cost. The traditional approaches for fouling control are mainly based on the physico-chemical principles, such as membrane modification, optimization of operational conditions, coagulant addition, cyclic filtration, etc, (Le-Clech et al, 2006, Yeon et al, 2009a, Meng et al, 2009) which may not be effective and less energy efficient. Tackling the fouling remains one of the major challenges to expand its application and significantly improve its general acceptance by industries.…”

A novel in-situ enzymatic cleaning method was developed for fouling control in membrane bioreactors (MBRs). It is achieved by bringing the required enzymes near the membrane surface by pulling the enzymes to a magnetic membrane (MM) surface by means of magnetic forces, exactly where the cleaning is required. To achieve this, the enzyme was coupled to a magnetic nanoparticle (MNP) and the membrane it self was loaded with MNP. The magnetic activity was turned by means of an external permanent magnet. The effectiveness of concept was tested in a submerged membrane filtration using the model enzymesubstrate of Bacillus subitilis xylanase-arabinoxylan. The MM had almost similar properties compared to the unloaded ones, except for its well distributed MNPs. The enzyme was stable during coupling conditions and the presence of coupling could be detected using a high-performance anionexchange chromatography (HPAEC) analysis and Fourier transform infrared spectroscopy (FTIR). The system facilitated an in-situ enzymatic cleaning and could be effectively applied for control fouling in membrane bioreactors (MBRs).
