“…Thus, several studies focused their attention on a hybrid system as an alternative to the conventional MBR (C-MBR), trying to combine the advantages of biofilm and MBR processes in order to overcome some of the limitations of C-MBR. Results from recent research demonstrated that biofilm carriers can reduce the negative effect of suspended solids on the membrane surface and improve its filterability because of a low fouling rate (Leiknes and Ødegaard, 2001;Ivanovic and Leiknes, 2012). Although some studies have been made with Biofilm MBR there is no consensus and some results are controversial.…”

-In this paper, the influence of biofilm carriers in a MBR on the performance of organic matter and nitrogen removal and the influence on membrane fouling were evaluated. The configurations studied included a Conventional Membrane Bioreactor (C-MBR) and a Biofilm Membrane Bioreactor (BF-MBR) operated in parallel, both fed with domestic wastewater. Regarding organic matter removal, no statistically significant differences were observed between C-MBR and BF-MBR, producing an effluent with a Soluble COD concentration of 27 ± 9.0 mgO 2 /L and 26 ±1.0 mgO 2 /L and BOD concentration of 6.0 ± 2.5 mgO 2 /L and 6.2 ± 2.1 mgO 2 /L, respectively. On the other hand, the BF-MBR produced a permeate with lower ammonia and total nitrogen concentrations, which resulted in a removal efficiency of 98% and 73%, respectively. It was also observed that the fouling rate was about 35% higher in the C-MBR than that for the BF-MBR, which also presented a reduction of total membrane resistance, about 29%, and increased operational cycle length around 7 days, compared to C-MBR.

“…They are based on the transfer of a gaseous electron donor or acceptor across a hydrophobic membrane (Ivanovic and Leiknes, 2012;Nerenberg, 2016) and have only recently been use as a commercial product, which is not established within the nutrient removal market (Martin and Nerenberg, 2012). MABRs behave differently to conventional biofilms due to the presence of gas exchange, adding a layer of complexity to the treatment process (Martin and Nerenberg, 2012).…”

The removal of phosphorus (P) from domestic wastewater is primarily to reduce the potential for eutrophication in receiving waters, and is mandated and common in many countries. However, most P-removal technologies have been developed for use at larger wastewater treatment plants that have economies-of-scale, rigorous monitoring, and in-house operating expertise. Smaller treatment plants often do not have these luxuries, which is problematic because there is concern that P releases from small treatment systems may have greater environmental impact than previously believed. Here P-removal technologies are reviewed with the goal of determining which treatment options are amenable to small-scale applications. Significant progress has been made in developing some technologies for small-scale application, namely sorptive media. However, as this review shows, there is a shortage of treatment technologies for P-removal at smaller scales, particularly sustainable and reliable options that demand minimal operating and maintenance expertise or are suited to northern latitudes. In view of emerging regulatory pressure, investment should be made in developing new or adapting existing P-removal technologies, specifically for implementation at small-scale treatment works.

“…The apparent volume of the granular and sponge carriers introduced into the MBRs was 5% of the reactor volume, which was determined based on the authors' previous research [7]. The rope carrier and sponge carrier used in this study are used in integrated biofilm activated sludge (IFAS) and moving bed biofilm reactor (MBBR) applications [19]. The rope carriers were fixed in the reactor to prevent contact with the membrane surface.…”

a b s t r a c tIt has been reported that the combination process of biofilm and submerged membrane bioreactors (MBRs) can mitigate membrane fouling. In this study, the influence of using three different biofilm carriers (fixed rope carrier, moving granular carrier and moving sponge carrier) on the operation and membrane fouling of MBRs was investigated. Using rope or sponge carriers with MBR processes improved the removal efficiency of nitrogen via the creation of an anoxic part inside the carriers. However, membrane fouling became very severe when rope carriers were used. Using granular or sponge carriers effectively mitigated membrane fouling because they mechanically cleaned the membrane surface. The cake/gel layer on the membrane surface was perfectly removed by granular or sponge carriers. However, the deterioration of the filterability of the mixed liquor suspensions was significant with granular carriers, leading to the evolution of physically irreversible fouling, whereas such deterioration was insignificant with the sponge carrier. The characteristics of the soluble microbial products (SMP) significantly varied depending on the types of carriers used, which could influence the filterability of mixed liquor suspensions and the development of irreversible membrane fouling.
