“…The quorum quenching caused to prevent biofouling since quorum sensing interrupts the biological communication mechanism between microorganisms. This was achieved with rotational membrane filtration modules [101] UV light Ultraviolet (UV) light penetrates the cell wall and damages the DNA and RNA, thus stopping the microorganism from reproducing. Furthermore, the main advantage is that it does not produce chemical by-products that can affect health.…”

Membranes, as the primary tool in membrane separation techniques, tend to suffer external deposition of pollutants and microorganisms depending on the nature of the treating solutions. Such issues are well recognized as biofouling and is identified as the major drawback of pressure-driven membrane processes due to the influence of the separation performance of such membrane-based technologies. Herein, the aim of this review paper is to elucidate and discuss new insights on the ongoing development works at facing the biofouling phenomenon in membranes. This paper also provides an overview of the main strategies proposed by “membranologists” to improve the fouling resistance in membranes. Special attention has been paid to the fundamentals on membrane fouling as well as the relevant results in the framework of mitigating the issue. By analyzing the literature data and state-of-the-art, the concluding remarks and future trends in the field are given as well.

“…After the X-Gal solution was prepared using dimethylformamide (DMF), which was bought from Merck (Germany), it was kept at -20 °C and in the dark. Microfiltration membrane was a polyvinylidene fluoride (PVDF) membrane (Microdyn Nadir GmbH, Germany) and had a nominal pore size of 0.20 μm and thickness of 210-250 μm (Ergön-Can et al, 2017). All synthetic wastewater ingredients were also supplied from Sigma-Aldrich (USA).…”

“…With this aim, a batch experimental setup was prepared. Inoculated BH4 bacteria were centrifuged and BH4 with the same amount used in the RMCF studies (Köse-Mutlu et al, 2019;Ergön-Can et al, 2017), which is approximately 25 mg dry weight of biomass per ml, added into the synthetic wastewater. The composition of the synthetic wastewater was the same as the recipe given in the section of the batch study.…”

“…MBR-A, MBR-B, and MBR-C were operated under the constant flux condition by using a microfiltration system consisting of the hollow fiber membrane module. Membrane module properties and dimensions were the same as in the previous study (Ergön-Can et al, 2017). While the effective area of the hollow fiber membranes in the module was around 100 cm 2 , the hydraulic retention time (HRT) and sludge retention time (SRT) were kept as 13 h and 30 d, respectively.…”

“…However, QQ applications for biofouling control in the MBR can raise difficulties and carried studies presented that QQ alginate beads as an immobilization media are nondurable and QQ microbial vessels have a low foodto-microorganism ratio to could cause the growth inhibition of QQ bacteria. In our previous studies (Köse-Mutlu et al, 2016;Ergön-Can et al, 2017) a new approach on the immobilization media to overcome these drawbacks of QQ-controlled MBR has suggested. Rotary microbial carrier frame (RMCF) was manufactured from a polycarbonate multi-frame covered by microfiltration membrane.…”

Quorum Quenching (QQ) is a mechanism that prevents cell to cell communication and has recently used as an effective control method against biofouling in membrane bioreactors (MBRs). Rotary microbial carrier frame (RMCF) is an innovative application used in QQ-controlled MBRs that provides immobilization medium to QQ bacteria. However, it eventually caused to decrease in QQ activity as a result of a decline in the number of viable QQ cells in the immobilization media over time, especially during long-term MBR operations. In this study, the effect of regeneration of the QQ cells in the immobilization media on biofouling control in MBR was investigated. The growth kinetic of Rhodococcus sp. BH4 as model QQ bacteria was revealed and the bacteria regeneration time was obtained as 28.3 days. In the operation of the regenerated group, an additional QQ activity of 38.2% was achieved compared to control during a 14 day-duration of QQ-controlled MBR operation. It could be indicated that regenerated QQ bacteria reduced SMP and EPS by degrading the signal molecules, thus more efficient control of membrane fouling was achieved.

In today's World, the recovery, reuse, and recycling of water turn heads more with the continuing water scarcity, and this requires a development of conventional wastewater treatment technologies. Membrane bioreactors (MBRs) can provide many advantages over the conventional activated sludge systems. However, biofouling problem restricts the potential widespread application of MBRs. The main reason for this is the increase in the operating costs. Nowadays, there are much research to elucidate and control the membrane fouling in MBR. In fact, it is difficult to find an effective solution for biofouling problem without heading toward to biological concepts, because the biomass matrix is significantly complex and includes various living microorganisms. Quorum quenching (QQ) mechanism aims to prevent the signaling for communication and group behaviors. For the last five years, the development of antibiofouling strategies based on QQ in MBRs has been a relatively hot topic in biofouling research. QQ is a natural process which is not harmful to the environment. Therefore, unquestionably, studies on QQ in MBR represent a promising alternative for controlling biofouling for future applications. This article explains the quorum sensing (QS) and QQ concepts and presents various and highly successful examples for enzymatic, bacterial, and fungal QQ MBR operations.
