“…MBRs are being employed in this application 176,177 and thus NMs-MBRs also have potential. With the increasing shift from waste treatment to resource recovery, nutrients (nitrogen and phosphorus) recovery is another key area; in this context, hybrid systems including MBRbased hybrids have been recommended 178 . With an emphasis on reducing energy use and recovering resources, anaerobic MBRs are being investigated extensively 179 .…”

The concept of nanomaterials membranes (NMs) promises to be a sustainable route to improve the membrane characteristics and enhance the performance of membrane bioreactors (MBRs) treating wastewater. This paper provided a critical review of recent studies on the use of membranes incorporating nanomaterials in membrane bioreactor (NMs-MBR) applications for wastewater treatment. Novel types of nanomaterials membranes were identified and discussed based on their structural morphologies. For each type, their design and fabrication, advances and potentialities were presented. The performance of NMs-MBR system has been summarized in terms of removal efficiencies of common pollutants and membrane fouling. The review also highlighted the sustainability and cost viability aspects of NMs-MBR technology that can enhance their widespread use in wastewater treatment applications.

“…These membranes facilitate the conversion of ammonium into ammonia or enhance the mass transfer of the target compound. The use of electrochemical cells such as CDI, ED, and BDI can efficiently produce nutrients or rare element-enriched streams from wastewater or seawater [ 85 , 86 , 105 , 106 , 107 , 108 , 109 , 110 ], primarily because most of the nutrients in wastewater are present in ionic forms, and the electrochemical process separate (or intercalate) the charged ions using electrostatic (or Faradaic) reactions. For instance, a three-staged BDI system successfully produced an ammonium-enriched stream from 5 mM to 32 mM using synthetic wastewater [ 85 ].…”

Membrane and Electrochemical Processes for Water Desalination: A Short Perspective and the Role of Nanotechnology

2020

In the past few decades, membrane-based processes have become mainstream in water desalination because of their relatively high water flux, salt rejection, and reasonable operating cost over thermal-based desalination processes. The energy consumption of the membrane process has been continuously lowered (from >10 kWh m−3 to ~3 kWh m−3) over the past decades but remains higher than the theoretical minimum value (~0.8 kWh m−3) for seawater desalination. Thus, the high energy consumption of membrane processes has led to the development of alternative processes, such as the electrochemical, that use relatively less energy. Decades of research have revealed that the low energy consumption of the electrochemical process is closely coupled with a relatively low extent of desalination. Recent studies indicate that electrochemical process must overcome efficiency rather than energy consumption hurdles. This short perspective aims to provide platforms to compare the energy efficiency of the representative membrane and electrochemical processes based on the working principle of each process. Future water desalination methods and the potential role of nanotechnology as an efficient tool to overcome current limitations are also discussed.

“…Moreover, the presence of aquaporins in the examined membranes is further confirmed with phosphodiester groups, found in membrane phospholipids (1240 cm -1 ) [55]. The specific functional groups of the PSf substrate layer in the TFC membranes appear at peaks 1150 cm -1 (symmetric SO 2 stretching vibration), at 1321-1296 cm -1 (asymmetric SO 2 stretching), 1240 cm -1 (asymmetric C-O-C stretching vibration), 1487 cm -1 (CH 3 -C-CH 3 stretching C-C in-ring bond in aromatic compounds) and 1410-1400 cm -1 (C=C aromatic ring stretching) [30], [46], [49]. Moreover, the presence of band 1583-1545 cm -1 (amino scissoring groups of primary amines), could further reveal protein deposits as part of fouling residues in rinsed membranes [58].…”

Forward osmosis is a low-energy water treatment emerging technology, which has demonstrated improved solute rejection and low fouling propensity. In this study, the applicability of aquaporinbased forward osmosis membranes during separation of biogas digestate liquid fractions was investigated. The results showed that Total Ammonia-Nitrogen rejection was higher than 95.5% in all experiments, independently of the type of draw solution (NaCl and hide preservation effluents), experimental period and the use of feed acidification. The results also confirmed that high draw osmotic pressures (i.e. 3.5M sodium chloride and hide preservation wastewater) combined with feed acidification had a negative effect on the membrane water permeability. Membrane rinsing after fouling was also successful in recovering the membrane initial water flux as well as removing 2 the remaining foulants on the membrane surface. The membrane inspection results from Scanning-Electron Microscope, Energy-Dispersive X-Ray analysis and Fourier Transform Infrared-Attenuated Total Reflectance showed that fouling in this application was mild and reversible after membrane rinsing. The applicability of aquaporin-based forward osmosis membranes during separation of biogas digestate liquid fractions has been demonstrated. The results showed the potential of this technology to achieve enhanced ammonia-nitrogen rejections and low-fouling propensity.
