Abstract This study endeavors to augment the antibacterial and anti‐biofouling properties of thin‐film composite polyamide membranes by subjecting them modification with chitosan silver nanoparticle materials through UV‐induced graft polymerization technique. Various surface assessment methods were employed, efficiency membrane performance was demonstrated flux retention filtration process, whi...

This study aimed to investigate the performance of composite photocatalytic membranes fabricated by incorporating multiple nanoparticles (TiO2, carbon nanotubes, BiVO4) into polyvinylidene fluoride membrane material for real dairy wastewater treatment. The exhibited superior antifouling behavior, lower filtration resistance, better flux, and higher flux recovery ratio than pristine membrane. Sa...

Biofouling is a worldwide phenomenon plaguing mariners and accounting for economic burden on shipping, aquaculture and various other maritime industries. The fouling organisms cause extensive damage to commercially important marine structures causing increased drag of marine surface and submarine vessels incurring increased fuel penalties. . Antifouling is the phenomenon of preventing biofoulin...

The tributyltin-based products and organic biocides which are incorporated into antifouling paints have had a negative impact on the marine environment, and the ban on tributyltin-based antifouling products has urged the industry to find substitutes to prevent the development of fouling on ship hulls. Natural antifouling agents could be isolated from marine resources, providing an alternative o...

Antifouling biocides such as organotin compounds and their alternatives are potent toxicants in marine ecosystems. In this study, we employed several molecular and biochemical response systems of the Pacific oyster Crassostrea gigas to understand a potential mode of action of antifouling biocides (i.e. tributyltin (TBT), diuron and irgarol) after exposure to different concentrations (0.01, 0.1,...

Biofouling is the undesirable growth of organisms on artificial and natural structures immersed in either seawater or freshwater. It causes huge economic loss and also the global prohibition on known antifouling agents has led to increase hunt for safe and effective antifouling agents. In the past, marine natural products have shown tremendous potential by providing new skeletons which could be...

Cellulose-based materials have been advanced technologies that used in water remediation. They exhibit several advantages being the most abundant biopolymer nature, high biocompatibility, and contain functional groups. Cellulose can be prepared derivatives including nanomaterials such as cellulose nanocrystals (CNCs), nanofibrils (CNFs), TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-medi...
