Water contamination caused by heavy metals, nutrients, and organic pollutants of varying particle sizes originating from domestic and industrial processes poses a significant global challenge. There is a growing concern, particularly regarding the presence of heavy metals in freshwater sources, as they can be toxic even at low concentrations, posing risks to human health and the… Continue reading Novel eco-friendly polylactic acid nanocomposite integrated membrane system for sustainable wastewater treatment: Performance evaluation and antifouling analysis
This study assesses the performance of waste sugarcane bagasse ash (SBA)-based ceramic membrane in anaerobic membrane bioreactor (AnMBR) treating low-strength wastewater. The AnMBR was operated in sequential batch reactor (SBR) mode at hydraulic retention time (HRT) of 24 h, 18 h, and 10 h to understand the effect on organics removal and membrane performance. Feast-famine… Continue reading Performance of Anaerobic Membrane Bioreactor (AnMBR) with Sugarcane Bagasse Ash-based Ceramic Membrane treating Simulated Low-strength Municipal Wastewater: Effect of Operation Conditions
The continued use of non-biodegradable polymeric-based membranes for water purification has led to an unsustainable accumulation of waste at disposal, resulting in various environmental problems. In this study, eco-friendly asymmetric ultrafiltration (UF) membranes were fabricated from polylactic acid (PLA) with different polymer concentrations using the phase inversion method. The fabricated membranes were characterized using Fourier… Continue reading Asymmetrical ultrafiltration membranes based on polylactic acid for the removal of organic substances from wastewater
This study focused on the surface modification of commercial TiO2 membranes with Fe3O4 decorated silver (Ag) nanoparticles (Fe3O4–Ag) via chemical attachment. Firstly, the Ag concentration on Fe3O4 was optimized, and different composites were prepared and characterized. Secondly, the optimal composite was used to prepare novel TiO2/Fe3O4–Ag ceramic membranes via surface coating through tetraethyl orthosilicate (TEOS)… Continue reading TiO2 ceramic membrane decorated with Fe3O4–Ag composite nanoparticles for produced water treatment
The effect of addition of algae to activated sludge as active biomass in membrane bioreactors (MBRs) and electro-MBRs (e-MBRs) for wastewater remediation was examined in this study. The performances of Algae-Activated Sludge Membrane Bioreactor (AAS-MBR) and electro Algae-Activated Sludge Membrane Bioreactor (e-AAS-MBR) were compared to those observed in conventional MBR and e-MBR, which were previously… Continue reading Wastewater treatment and fouling control in an electro algae-activated sludge membrane bioreactor
Water is needed for food processing facilities to carry out a number of tasks, including moving goods, washing, processing, and cleaning operations. This causes them to produce wastewa-ter effluent, and they are typically undesirable since it contains a high volume of suspended solids, bacteria, dyestuffs, salts, oils, fats, chemical oxygen demand and biological oxygen demand.… Continue reading Sustainable treatment of food industry wastewater using membrane technology: A short review

This paper focused on the combination of membrane ultrafiltration, adsorption and ultrasound processes in one hybrid process called USAMe for improving membrane wastewater treatment performance and membrane fouling control. Different tests were conducted at different ultrasound frequencies and recycle ratio. Improved permeate quality in the USAMe process. Membrane fouling reduction with the combined application of… Continue reading Influence of membrane flux, ultrasonic frequency and recycle ratio in the hybrid process usame
Membrane ultrafiltration is increasingly applied for wastewater treatment and reuse, even though membrane fouling still represents one of the main drawbacks of this technology. In the last years, innovative strategies for membrane fouling control have been developed, such as the combination of membrane processes with ultrasound (US). In present work, the application of membrane ultrafiltration… Continue reading Wastewater treatment by membrane ultrafiltration enhanced with ultrasound: Effect of membrane flux and ultrasonic frequency
Membrane bioreactors (MBRs) are a well established and mature technology with many full-scale plants around the world treating municipal and industrial wastewater (Krzeminski et al. in J. Membr. Sci. 527:207–227, 2017). © Springer International Publishing AG 2018.
