“…However, the biggest drawback of using membranes is their susceptibility to fouling during filtration (Baitalow et al, 2021; Sreedhar et al, 2018). This phenomenon occurs due to the formation of a polarization layer on the membrane surface (Guo et al, 2012), which results in the deposition of various components on the membrane surface and in the pores (Aslam et al, 2022), leading to adsorption or blockage and a significant reduction in their efficiency (Tanudjaja et al, 2022). Significant efforts have been made by scientists to mitigate or prevent the occurrence of this phenomenon; at the same time, recent technological advancements have introduced 3D printing to the field of water and wastewater treatment, revolutionizing traditional manufacturing methods (Ng et al, 2021; Thomas et al, 2019).…”

The article evaluates the effectiveness of two new designed module‐integrated 3D printed spacers in enhancing wastewater ultrafiltration efficiencies using Vibratory Shear Enhanced Processing (VSEP). The study investigates the star‐shaped spacer filled module channel (Star spacer) and the column‐shaped herringbone spacer filled module channel with the same position as the flow direction (Column spacer) and with the opposite position as the flow direction (Rev column spacer). It compares the VSEP module‐integrated spacers with membrane module vibration (Module vibration) and empty membrane module channel (Control) configurations. The results show that the module integration of the 3D printed spacers can greatly improve the specific, average and constant permeate fluxes and can contribute to reducing the total, reversible and irreversible resistance values and specific energy consumption of the ultrafiltration membrane separation experiments. Overall, this study provides valuable insights into improving the performance of wastewater ultrafiltration systems and fouling mitigation through the module‐integration of 3D printed spacers and membrane module vibration.

“…Despite intensive research and the promising potential of membrane separation processes, fouling remains a severe problem in membrane filtration and can prevent continuous and large-scale operation of membrane separation processes [13][14][15]. Numerous studies have been carried out to identify the organic compounds responsible for membrane fouling and to gain a better understanding of the fouling mechanism.…”

“…Despite the extensive research that has been conducted, there is still much to be learned about the nature of organic fouling and the factors that contribute to it. More research is needed to develop effective fouling mitigation strategies and to improve the performance and efficiency of membrane-based water treatment processes [13][14][15][16].…”

Membrane separation processes have become increasingly popular in many industries because of their ability to treat wastewater and purify water. However, one of the main problems related to the processes is organic fouling, which can significantly reduce their efficiency and cause membrane damage. This review provides a summary of the various forms of organic fouling that can occur in membrane separation methods and examines the factors that lead to their development. The article evaluates the progress made in different techniques designed to manage and reduce organic fouling, such as physical cleaning methods, chemical cleaning agents, and modifications to the membrane surface, including ultrasonic and membrane vibration methods. The review also highlights recent advances in emerging 3D printing technology to mitigate membrane fouling. Finally, the review provides a brief summary of the conclusions and future directions for research in the field of organic fouling control and mitigation in membrane separation processes.

“…Water hammers can cause cavitation, as shown by Jansson et al [16] by means of a high speed camera. Aslam et al [17] have shown that the water hammer effect can be used to prevent membrane fouling. Considering whey protein ultrafiltration they achieved up to 84% flux enhancement.…”

Energy Intake Models for Intermittent Operation of Dead-End Microfiltration Filling Line

et al. 2022

View full text Add to dashboard Cite

In filling lines equipped with membrane separation devices in the form of filters energy, consumption is only one of the important working parameters, the other being sustainable filter performance in terms of separation efficiency. As the filling line is typically equipped with a valve, intermittent operation of the filter is an important form of its use. Whereas the overall energy consumption of the filtration process is governed by the continuous operation mode, the intermittent mode, characterised by opening/closing of the valve, contributes most to problems of filter failure, i.e., the breakthrough of filtered particles through the membrane. A model for determination of the energy intake of a microfiltration membrane during the opening and closing of a valve is presented in this work. The model is based on computational analysis of the pressure wave signals recorded during the opening/closing of the valve using Fourier transform, and expressed in a nondimensional filter area specific energy intake form. The model is applied to a case of constant pressure dead-end microfiltration with three filter types: a single membrane filter, a stacked filter and a pleated filter with filtration surface areas ranging from 17.7 cm2 to 2000 cm2. Both clean filters, as well as partially clogged filter cases are taken into account. Second order polynomial models of the energy intake are developed and evaluated based on extensive analysis of the experimental data. The analysis of energy intake results show that the largest energy intake was observed for the clean filter case. When membrane fouling occurs at the constant flow rate values it leads to larger energy intake, however, due to a decreasing specific flow rate during fouling these values do not exceed the clean filter case.
