“…BPCs act like glue, which helps the sludge to adhere to the surface of the membrane and form a cake layer. Wang et al [18] studied the formation process and fouling characteristics of dynamic membranes as well as an improved self-forming dynamic membrane bioreactor (SF-DMBR) for the recovery of organic matter in wastewater and to evaluate its properties. The results showed that 80% of the organic matter in the wastewater can be recovered faster in the case of continuous operation.…”

Compared with the traditional activated sludge process, a membrane bioreactor (MBR) has many advantages, such as good effluent quality, small floor space, low residual sludge yield and easy automatic control. It has a promising prospect in wastewater treatment and reuse. However, membrane fouling is the biggest obstacle to the wide application of MBR. This paper aims at summarizing the new research progress of membrane fouling mechanism, control, prediction and detection in the MBR systems. Classification, mechanism, influencing factors and control of membrane fouling, membrane life prediction and online monitoring of membrane fouling are discussed. The research trends of relevant research areas in MBR membrane fouling are prospected.

“…The sieve rejection rate was determined to be a key parameter for regulating critical flux, lowering biomass concentration in the MBR, and enhancing membrane permeability. Wang, Liu, et al (2018) researched the coagulation efficiency of three hydrous aluminum species (Al a , Al b , and Al c ) concerning floc properties, humic acid removal, and ANNUAL LITERATURE REVIEW reversible and irreversible membrane fouling. All three coagulants reduced membrane fouling and decreased the humic acid species as the coagulant dose increased.…”

“…On the other hand, more insoluble chitosan will cause a hole in the membrane. According to Wang [28] and Liu [29], the large flux value is influenced by the membrane-forming concentration; the higher the concentration of membrane-forming polymer, the resulting membrane is denser, resulting in smaller flux. The water permeability graph of all membranes in every 5 seconds can be seen in Fig.…”

The purification process of sugarcane juice in a sugar factory mostly uses sulphitation process, separating clear juice from dirty juice using a sedimentation system. Impurities on the processing of sugarcane juice will further cause difficulties, the formation of color, an increase in viscosity, and reducing sugar recovery. Membrane purification technology is offered to overcome these problems. This study aims to determine the effect of chitosan and acetic acid on the performance of chitosan membranes in the clearance of sugarcane juice and to find the best concentration of chitosan and acetic acid for the purification process of sugarcane juice. The filtration process was performed by using the chitosan membrane to process a clear sugarcane juice sample from the pretreatment result, which is assumed as clear juice product from sulphitation process in sugar factory. The results showed that (1) the result of pretreatment had the value from TSS (Total Soluble Solids) of 15.4%; turbidity of 82.33 NTU; and the ICUMSA (International Commission for Uniform Methods of Sugar Analysis) colour of 14970.02 IU. (2) After filtration using membrane, better quality of pretreatment clear sugarcane juice is obtained, characterized by increasing chitosan concentration at each acetic acid level, rejection value of TSS, turbidity, and ICUMSA colour. (3) The best treatment result based on Zeleny multiple attribute method is found in chitosan membrane with concentration of 4%, acetic acid concentration of 1.5% to inject TSS until reaching 12.64%, ICUMSA until reaching 9.89%, and rejection of turbidity until reaching 63.61%. Higher chitosan concentration caused small pore size of the membrane.
