“…The removal of COD with all membranes is presented in Figure 3 , where the RO percentage removal of 92% and 99% for uncontrolled and controlled pH, respectively, were significantly higher than the UF and NF membranes ( p = 0.018 for UF, p = 0.013 for NF and p = 0.009 for RO; α = 0.05). This is consistent with a similar study of MBR/NF and MBR/RO membrane effluent rejection [ 26 ]. MBR is considered a relatively improved treatment process for the exclusions of COD compared to conventional activated sludge processes as a pre-treatment for NF and RO reuse [ 10 ].…”

“…The earth may appear wet, but if the EC is high, then the available water to the vegetations will be less. The acceptable EC limits for effluent discharge and domestic water supply usage, according to South African guidelines, are 250 µS•cm −1 and 70 µS•cm −1 , respectively [26]. The results in Table 5 show that the removal of phosphate, phosphorous, and ammonia with MBR/NF270 and MBR/XLE membranes is within the specification guidelines for cooling and irrigation applications.…”

“…As expected, the MBR/UF effluent with an EC of 471 µS•cm −1 is only suitable for cooling system reuse application. Falizi et al (2018) [26] cautions that water salinity (measured by EC) is the primary factor threatening crop productivity and quality with the usage of irrigation water at a pH between 6 and 9. The earth may appear wet, but if the EC is high, then the available water to the vegetations will be less.…”

Membrane technology has advanced substantially as a preferred choice for the exclusion of widespread pollutants for reclaiming water from various treatment effluent. Currently, little information is available about Ultrafiltration (UF)/Nanofiltration (NF)/Reverse Osmosis (RO) performance at a pilot scale as a practical engineering application. In this study, the effluent from a full-scale membrane bioreactor (MBR) municipal wastewater treatment works (MWWTWs) was treated with an RO pilot plant. The aim was to evaluate the effect of operating conditions in the removal of selected inorganics as a potential indirect water reuse application. The influent pH, flux, and membrane recovery were the operating conditions varied to measure its influence on the rejection rate. MBR/RO exhibited excellent removal rates (>90%) for all selected inorganics and met the standard requirements for reuse in cooling and irrigation system applications. The UF and NF reduction of inorganics was shown to be limited to meet water standards for some of the reuse applications due to the high Electron Conductivity (EC > 250 μS·cm−1) levels. The MBR/NF was irrigation and cooling system compliant, while for the MBR/UF, only the cooling system was compliant.

“…MBR processes are usually considered as a pre-treatment step for NF and RO processes, because they exhibit high tolerance at total suspended solids of influent composition variation, and production of high effluent quality ( Table 3 in Refs. [47,48]) However, the membrane fouling is a major hurdle on applying MBR processes at larger scale. An approach to circumvent this hurdle is to increase the membranes' hydrophilicity via incorporating inorganic nanocrystals (nanofillers) in polymeric membranes, also named organic-inorganic mix-matrixed membranes (MMM) [49].…”

The global agricultural sector consumes a large amount of fresh water for irrigation. Less than half of agricultural wastewater is properly treated before discharging to environment or recycling. Treatment of agricultural wastewater for reuse in irrigation can alleviate burden on water resources as well as protect the environment from detrimental effects caused by various organics, pesticides, and soluble ions in the wastewater stream. This work reviews several current membrane technologies that are applied at removing the pollutants in agricultural wastewater. Subsequently, several strategies to further improve membranes' performance are highlighted. The advancement of materials science at the nanometer scale can assist the fabrication of membranes with higher selectivity of pollutant removal, higher permeate flux, and lower membrane fouling.

“…Based on the literature, it is evident that in recent years, remarkable progress has been made in wastewater treatment via MBR technology. Wastewater reuse has been targeted 11,12 and a range of industrial wastewaters have been tested 13,14 . Of particular interest are highly polluting effluents from sectors, such as tanneries 15 and textiles 16,17 , as well as wastewaters with high salinity 18 .…”

View full text Add to dashboard Cite

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.
