“…They have been employed in analyzing the experimental results in oily wastewater treatment using membranes. [13,28,35,59,65] In these fouling models, the foulant particles which enter the pores of the membrane or strongly adsorb on the membrane surface can contribute to irreversible fouling. Otherwise, they can be easily washed away and contribute to the reversible fouling.…”

Oily wastewater is an extensive source of pollution to soil and water, and its harmless treatment is of great importance for the protection of our aquatic ecosystems. Membrane filtration is highly desirable for removing oil from oily water because it has the advantages of energy efficiency, easy processing and low maintenance cost. However, membrane fouling during filtration leads to severe flux decline and impedes long-term operation of membranes in practical wastewater treatment. Membrane fouling includes reversible fouling and irreversible fouling. The fouling mechanisms have been explored based on classical fouling models, and on oil droplet behaviors (such as droplet deposition, accumulation, coalescence and wetting) on the membranes. Membrane fouling is dominated by droplet-membrane interaction, which is influenced by the properties of the membrane (e.g., surface chemistry, structure and charge) and the wastewater (e.g., compositions and concentrations) as well as the operation conditions. Typical membrane antifouling strategies, such as surface hydrophilization, zwitterionic polymer coating, photocatalytic decomposition and electrically enhanced antifouling are reviewed, and their cons and pros for practical applications are discussed.

“…For these reasons, membrane processes are often recognized as the best available technology (BAT) in the food industry [ 2 , 3 , 4 ]. Among pressure-driven membrane processes, ultrafiltration (UF) has been extensively applied in the treatment of industrial effluents [ 5 , 6 , 7 , 8 , 9 , 10 ], oil-based emulsions [ 11 , 12 , 13 , 14 ], biological macromolecules [ 15 , 16 , 17 ], milk [ 18 , 19 , 20 ], sugar cane [ 21 , 22 ], extracts of soybean flour [ 23 ], clay suspensions [ 24 ], black kraft liquor [ 25 ], and fruit juices [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ] among others. Within the fruit juice industry, bergamot, kiwifruit, and pomegranate have great importance in the market, not only for their volume of production, but also because they are characterized by a high concentration of phytochemicals which are recognized to be associated with antioxidant activities within others.…”

Prediction of Permeate Flux in Ultrafiltration Processes: A Review of Modeling Approaches

et al. 2021

View full text Add to dashboard Cite

In any membrane filtration, the prediction of permeate flux is critical to calculate the membrane surface required, which is an essential parameter for scaling-up, equipment sizing, and cost determination. For this reason, several models based on phenomenological or theoretical derivation (such as gel-polarization, osmotic pressure, resistance-in-series, and fouling models) and non-phenomenological models have been developed and widely used to describe the limiting phenomena as well as to predict the permeate flux. In general, the development of models or their modifications is done for a particular synthetic model solution and membrane system that shows a good capacity of prediction. However, in more complex matrices, such as fruit juices, those models might not have the same performance. In this context, the present work shows a review of different phenomenological and non-phenomenological models for permeate flux prediction in UF, and a comparison, between selected models, of the permeate flux predictive capacity. Selected models were tested with data from our previous work reported for three fruit juices (bergamot, kiwi, and pomegranate) processed in a cross-flow system for 10 h. The validation of each selected model's capacity of prediction was performed through a robust statistical examination, including a residual analysis. The results obtained, within the statistically validated models, showed that phenomenological models present a high variability of prediction (values of R-square in the range of 75.91–99.78%), Mean Absolute Percentage Error (MAPE) in the range of 3.14–51.69, and Root Mean Square Error (RMSE) in the range of 0.22–2.01 among the investigated juices. The non-phenomenological models showed a great capacity to predict permeate flux with R-squares higher than 97% and lower MAPE (0.25–2.03) and RMSE (3.74–28.91). Even though the estimated parameters have no physical meaning and do not shed light into the fundamental mechanistic principles that govern these processes, these results suggest that non-phenomenological models are a useful tool from a practical point of view to predict the permeate flux, under defined operating conditions, in membrane separation processes. However, the phenomenological models are still a proper tool for scaling-up and for an understanding the UF process.

“…Controlling membrane fouling and minimizing accumulation of foulants fall within four main strategies involving membrane modification, membrane cleaning, optimization of operating parameters and feed water pre‐treatment (Figure 2) (Zoubeik et al, 2018). Several studies related to oily wastewater have been reported and reviewed different fouling prevention strategies, for example, physical and chemical pre‐treatment options (Allen, 2008b; Fakhru'l‐Razi et al, 2009; Kharoua et al, 2010; Zheng et al, 2015), properties of oily wastewater related to membrane fouling (Alzahrani & Mohammad, 2014; Dickhout et al, 2017), effects of operating parameters on the membrane performance (Padaki et al, 2015; Reyhani & Mashhadi Meighani, 2016; Seyed Shahabadi & Reyhani, 2014), membrane cleaning techniques (Burnett & Vance, 2007; Drewes et al, 2008; Patil et al, 2021) and membrane materials and modification (Huang, Wang, et al, 2015; Padaki et al, 2015; Pagidi et al, 2014; Salahi, Mohammadi, Behbahani, & Hemati, 2015; Salahi, Mohammadi, Mosayebi Behbahani, & Hemmati, 2015; Zoubeik et al, 2018).…”

While oil sands production plays a significant role in Canada's economy, the rise in oil sands production leads to increasing water withdrawal, consumption, storage and contamination that threaten the sustainability of water sources, biodiversity, ecosystem and public health. Effective treatment and reuse of oil sands process‐affected water (OSPW) can be a strategic solution for these issues. Membrane technology has emerged as a favourite choice for OSPW treatment with high removal and energy efficiency, small footprint and facile operation, installation and scale‐up. However, challenges also exist for membrane technologies related to fouling that causes a rapid decline in membrane performance. Mixed matrix membranes (MMMs) prepared by mixing superhydrophilic zwitterionic materials and inorganic nanoparticles into host membranes are anticipated as next‐generation membrane designs with significant potential for OSPW treatment by achieving multifunctionalities including fouling resistance, improved water permeability, selectivity and mechanical strength. Reproducibility and feasibility for large‐scale industrial applications remain important research questions for the production of MMMs for OSPW treatment. This study provides new insight on the performance, stability and durability of MMMs, outlooking to the commercialization prospect of MMMs. The research outcomes therefore can provide valuable knowledge for the design and development of high‐quality membranes with the required characteristics for OSPW treatment applications.
