“…Mg 2+ and Ca 2+ sources and pH adjustment methods would be required to achieve the initial conditions for the precipitation process, while the performance of these systems could be affected by several parameters. Influent quality, hydraulic load, salinity, membrane fouling (organic, inorganic, or biological fouling) are the most important ones [60,74].…”

Abstract:Phosphorus is an essential nutrient for every organism on the Earth, yet it is also a potential environmental pollutant, which may cause eutrophication of water bodies. Wastewater treatment plants worldwide are struggling to eliminate phosphorus from effluents, at great cost, yet current research suggests that the world may deplete the more available phosphorus reserves by around 2300. This, in addition to environmental concerns, evokes the need for new phosphorus recovery techniques to be developed, to meet future generations needs for renewable phosphorus supply. Many studies have been, and are, carried out on phosphorus recovery from wastewater and its sludge, due to their high phosphorus content. Chemical precipitation is the main process for achieving a phosphorus-containing mineral suitable for reuse as a fertilizer, such as struvite. This paper reviews the current status and future trends of phosphorus production and consumption, and summarizes current recovery technologies, discussing their possible integration into wastewater treatment processes, according to a more sustainable water-energy-nutrient nexus.

“…Forward osmosis has recently been implemented in osmotic MBRs (Wang et al, 2016), which show effectiveness in combating membrane fouling. Novel membrane types that are designed to pose minimum fouling propensity is also effective Kharraz et al, 2015;Marbelia et al, 2016).…”

Membrane bioreactors (MBRs) have recently become widely accepted as an advanced technology for treatment of domestic and industrial wastewaters. The objective of this review is to provide overview on MBR technology for wastewater treatment application. It includes discussions on the fundamental, core problems (membrane fouling), recent effective development approach (dynamic filtration systems) and future research direction of MBRs. Since MBRs integrate a conventional activated sludge process with membrane filtration, and both fundamental aspects are discussed first. Later, a comprehensive discussion about membrane fouling, the main problems in MBR, is provided, including fouling control strategies. The discussion on the MBR membranes and relation between membrane properties and MBR performance is also provided. This review also includes one of the most promising MBR technologies that specifically design to manage membrane fouling: dynamic filtration systems. Lastly, insight into an approach to address MBRs challenges and recent research and developments are provided.

“…For instance, the low SRSF values of SOA, KH 2 PO 4 and MAP are most likely related to their low B parameters (i.e., 0.022, 0.029 and 0.024 kg·m 2 ·h −1 , respectively). A draw solution exhibiting a lower SRSF would be the preferred option for this hybrid MF-FDFO-MBR system since the accumulation of inorganic salt ions in the bioreactor could potentially inhibit the aerobic microbial activity [14]. For that reason, SOA or KH 2 PO 4 would be more suitable for this process.…”

“…The high rejection of FO membrane can therefore provide a better rejection of contaminants and retain a significant portion of suspended solids; which is another advantage of this OMBR system compared to the conventional ones. However, OMBR also has some limitations such as salinity build-up (i.e., accumulation of dissolved salts inside the bioreactor), internal concentration polarization and the energy associated with the draw solution recovery process [13][14][15]. This is due to the combination of high rejection of FO membrane which rejects the salts already present in the bioreactor and those coming from the wastewater feed solution and the reverse transport of salt from the draw solution to the bioreactor passing through the FO membrane [16,17].…”

In this paper, three different fertilizer draw solutions were tested in a novel forward osmosis-microfiltration aerobic membrane bioreactor (MF-FDFO-MBR) hybrid system and their performance were evaluated in terms of water flux and reverse salt diffusion. Results were also compared with a standard solution. Results showed that ammonium sulfate is the most suitable fertilizer for this hybrid system since it has a relatively high water flux (6.85 LMH) with a comparatively low reverse salt flux (3.02 gMH). The performance of the process was also studied by investigating different process parameters: draw solution concentration, FO draw solution flow rate and MF imposed flux. It was found that the optimal conditions for this hybrid system were: draw solution concentration of 1 M, FO draw solution flow rate of 200 mL/min and MF imposed flux of 10 LMH. The salt accumulation increased from 834 to 5400 µS/cm during the first four weeks but after integrating MF, the salinity dropped significantly from 5400 to 1100 µS/cm suggesting that MF is efficient in mitigating the salinity build up inside the reactor. This study demonstrated that the integration of the MF membrane could effectively control the salinity and enhance the stable FO flux in the OMBR.
