This paper aims to establish a new sustainable membrane with antifouling properties by developing a structured porous membrane with a honeycomb-like surface fabricated by blending polymers and additives via immersion precipitation and using a thermally induced phase inversion method coupled with exposure time to vapor. The hydrophilic properties, surface charge, and pore size of the membrane were… Continue reading Fabrication of a polyethersulfone/polyethyleneimine porous membrane for sustainable separation of proteins in water media
To enhance the green polylactic acid (PLA) membrane’s efficiency for removing organic materials, self-assembled functionalized graphene oxide carboxylic multi-walled carbon nanotubes (f-GO/MWCNTs-COOH) was incorporated into the membrane matrix followed by immersion precipitation. The successful formation of the negatively charged f-GO/MWCNTs-COOH nanohybrid was verified by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and zeta potential analyzer. The effect of… Continue reading High-performance f-GO/MWCNTs-COOH nanohybrid-based polylactic acid mixed matrix membrane for wastewater treatment
The treatability of synthetic textile wastewater containing model dyes, such as reactive black and direct black dye (25.0 ± 2.6 mgdye/L), with chemical oxygen demand (COD, 1000 ± 113 mg/L), ammonia‑nitrogen (NH3-N, 140 ± 97 mg/L) and sulphate ions (SO₄2−, 1357 ± 10.86 mg/L) was investigated in this study using an innovative living membrane bioreactor… Continue reading Living membrane bioreactor for highly effective and eco-friendly treatment of textile wastewater
Graphene oxide and multi-walled carbon nanotubes have recently attracted attention, as they have proved to have potential in various applications. Therefore, in this study, a positively charged functionalized multi-walled carbon nanotubes (f-MWCNT)-graphene oxide (GO) composite was prepared by the electrostatic attraction approach, as they are oppositely charged, to test for its potential in wastewater treatment… Continue reading Self-assembled Positively Charged MWCNT-GO Composites for Wastewater Treatment
This study presents the synthesis of a novel graphene oxide-manganese oxide (GO-MnO2) nanohybrid and its incorporation into sulfonated polyethersulfone (SPES) ultrafiltration (UF) membranes for wastewater treatment applications. The nanohybrid was first prepared by grafting ethylenediamine (ED) onto the edge of GO followed by direct mixing with the MnO2 nanosheets. The composite membranes were prepared via… Continue reading Highly selective heavy metal ions membranes combining sulfonated polyethersulfone and self-assembled manganese oxide nanosheets on positively functionalized graphene oxide nanosheets
The integration of nanoparticles in wastewater treatment technologies has become an attractive topic to improve the membrane’s hydrophilicity, which is a vital membrane property needed for the efficient removal of contaminants. Functionalized graphene oxide (FGO) and oxidized multi-walled carbon nanotubes were used to synthesize FGO/MWCNT-COOH nanocomposite. The components of the nanocomposite were characterized through thermogravimetric… Continue reading Self-assembled Negatively Charged GO-MWCNT Composite for Wastewater Filtration
The discharge of large volumes of oily wastewaters without sufficient treatment poses a huge risk on the environment. The main objective of this study was to investigate the capability of electro-coagulation/flotation (ECF) process for the removal of oil from industrial oily wastewater via different electrodes’ configuration. These included anode-cathode-anode-cathode (ACAC), anode-cathode-cathode-anode (ACCA), and cathode-anode-anode-cathode (CAAC)… Continue reading Impact of electrodes’ configuration in an electrokinetic cell for oil-water separation
The whey is a by-product rich in organic substances; the system, as conceived, is self-learning. © Springer Nature Switzerland AG 2020.
It is well known that wastewaters from the food industry are a potential source of valuable compounds, such that these wastewaters may be considered by-products awaiting the development of appropriate treatment methodologies. Whey is one of the most important polluting effluents from the milk industry because of its very high biological oxygen demand (BOD). Nevertheless,… Continue reading Fuzzy-assisted ultrafiltration of whey by-products recovery
Persulfate (PS)-activated, iron-based heterogeneous catalysts have attracted significant attention as a potential advanced and sustainable water purification system. Herein, a novel Fe3O4 impregnated graphene oxide (Fe3O4@GO)-activated persulfate system (Fe3O4@GO+K2S2O8) was synthesized by following a sustainable protocol and was tested on real wastewater containing dye pollutants. In the presence of the PS-activated system, the degradation efficiency… Continue reading New sustainable approach for the production of Fe3O4/Graphene oxide-activated persulfate system for dye removal in real wastewater
