“…Therefore, adequate removal of the solids before the submerged HF module is key to mitigating blocking. Methanogenic [125] and chlorinated [126] pretreatments have also been explored, as well as hybrid processes, both of which add an additional unit operation before the membrane module [127][128][129][130]. With respect to (ii), physical cleaning tends to remove reversible fouling while chemical cleaning can remove some irreversible fouling.…”

“…Extensive tests subsequently have been carried out [24,27,128,130,244,, especially in view of the potentially lower energy cost than that of bubbling [24,204] and suitability for the anaerobic MBR. Effects of treating different types of wastewater [258,259,261,262,276] (e.g., using municipal versus synthetic wastewater [24,258]), trace organics [128,278], membrane type [273] (including effects on membrane integrity [271,272,275]), screen size [259], fluidized media [236,244,279,280] (including size and packing amount [244,267,268,271,275]), operating conditions [260,271] such as temperature [260][261][262], scale [261], design [130,261,264,265,276] (e.g., single (AFMBR) versus two-stage (AFBR-AFMBR) systems [130]), which collectively proved the efficacy of GAC in scouring the membranes. Different embodiments of the AFMBR include single (AFMBR) versus two-stage (AFBR-AFMBR) systems …”

Abstract:The submerged membrane filtration concept is well-established for low-pressure microfiltration (MF) and ultrafiltration (UF) applications in the water industry, and has become a mainstream technology for surface-water treatment, pretreatment prior to reverse osmosis (RO), and membrane bioreactors (MBRs). Compared to submerged flat sheet (FS) membranes, submerged hollow fiber (HF) membranes are more common due to their advantages of higher packing density, the ability to induce movement by mechanisms such as bubbling, and the feasibility of backwashing. In view of the importance of submerged HF processes, this review aims to provide a comprehensive landscape of the current state-of-the-art systems, to serve as a guide for further improvements in submerged HF membranes and their applications. The topics covered include recent developments in submerged hollow fiber membrane systems, the challenges and developments in fouling-control methods, and treatment protocols for membrane permeability recovery. The highlighted research opportunities include optimizing the various means to manipulate the hydrodynamics for fouling mitigation, developing online monitoring devices, and extending the submerged HF concept beyond filtration.

“…Research to date has indicated that the system is excellent for removal of many micropollutants, and indeed in many cases, its removal capability exceeds that by conventional aerobic activated sludge systems. For example, Dutta et al (2014) reported that a lab-scale SAF-MBR system effectively removed the 20 pharmaceuticals they detected in primary settled domestic wastewater with medium removal of 96% and a range between 86-100% except for diclofenac (78%). In a comparable study by Yang et al (2011) using aerobic activated sludge treatment followed by membrane filtration for the treatment of primary treated domestic wastewater effluent, the median removal of 16 pharmaceuticals and personal care products was much less than with the anaerobic system or 79%, with a broad range of 0-100%.…”

The anaerobic fluidized bed membrane bioreactor (AFMBR) is a new energy-neutral methanogenic biological treatment system that combines an anaerobic fluidized bed reactor (AFBR) and internal membranes. It is unique in that the fluidized granular particles, while serving as a surface for active biofilm attachment, rub against membrane surfaces, resulting in a reduction in fouling with low energy expenditure. Fluidized particles denser than water permit good mass transfer, and allow for the maintenance of a large biological population, even at the short hydraulic retention time as required for dilute wastewater treatment. Membranes prevent the escape of volatile suspended solids so they can be biodegraded adequately and removed separately for subsequent disposal. The AFMBR can be used alone for wastewater treatment or as the second reactor in a staged treatment system. Laboratory and pilot studies with domestic wastewater with a staged AFBR-AFMBR system, both containing granular activated carbon particles and operated at total HRT near 6 h and temperatures down to 8 o C, have demonstrated high organic removal efficiency, low waste biosolids production (0.05 kg·kg-COD -1 ), microcontaminant removal efficiencies better than conventional aerobic activated sludge treatment, and a very small footprint. Further research on best approaches for dissolved methane capture and nutrient removal and recovery are ongoing.

“…No matter for waste sludge digestion or high-strength wastewater treatment, the stability and continuity must be primary factors to be considered for the 8 operation of digestor, which determines that a timely monitoring method is highly needed. Considering the high variability and sensitivity of an AD process, it might be the best option to adopt an on-line monitoring and controlling method based on the basic characteristics of the fluid within the bioreactor.…”
