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
This study was carried out with the scope of resource recovery platform from the food waste-based organic materials in the presence of in situ microfiltration immersed anaerobic membrane bioreactor. Afterwards, ultrafiltration technology was adopted. These microfiltration and ultrafiltration processes successfully removed larger particles, i.e., suspended solids from the anaerobically digested effluent. Moreover, ultrafiltration membranes (50 kDa)… Continue reading Microfiltration and Ultrafiltration as Efficient, Sustainable Pretreatment Technologies for Resource Recovery
The potential of organic waste streams (i.e., food waste) for the sustainable production of precursor chemicals such as volatile fatty acids (VFAs) using anaerobic digestion (AD) has received significant attention in the present days. AD-derived VFAs have great market appeal if the challenges with their recovery and purification from the complex AD effluent is overcome.… Continue reading Double-stage membrane-assisted anaerobic digestion process intensification for production and recovery of volatile fatty acids from food waste
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
Ultrafiltration mixed matrix membranes were prepared using polyvinylidene fluoride (PVDF) with functionalized mesoporous amino nano-silica (NS). The prepared functionalized mesoporous amino nano-silica (NS) was characterized using X-ray diffraction, transmission electron microscopy, and Fourier transform infrared. The results indicate that the addition of amino-functionalized nano-silica improves the hydrophilicity of the membrane. Membranes M5 and M6 showed… Continue reading Amino-functionalized mesoporous nano-silica/polyvinylidene fluoride composite as efficient ultrafiltration membrane
The low-level presence of emerging contaminants (ECs) in the environment has raised a great concern due to their persistence, chronic toxicological, and endocrine disrupting effects on terrestrial and aquatic organisms. Wastewater treatment plants (WWTPs) have become hotspots for the spread of these contaminants to the environment as conventional processes are not efficient in removing them.… Continue reading Removal of contaminants of emerging concern from real wastewater by an innovative hybrid membrane process – UltraSound, Adsorption, and Membrane ultrafiltration (USAMe®)
Global consideration has been growing recently to tackle the toxic and carcinogenic effects of heavy metal presence in water streams. In this work, novel polyvinylidene fluoride (PVDF)/tin(IV) oxide (SnO2) ion exchange membranes were prepared via the phase inversion method and their performance and properties were analyzed. The results showed that the addition of SnO2 nanoparticles… Continue reading Preparation of novel polyvinylidene fluoride (PVDF)-Tin(IV) oxide (SnO2) ion exchange mixed matrix membranes for the removal of heavy metals from aqueous solutions
