چکیده

Abstract Anti-fouling properties and chlorine resistance nature are highly desirable features for membranes used in nanofiltration (NF). Conventional polymeric NF often suffer from fouling issues poor stability under based chemicals. Therefore, this work, a thin film composite (TFC) membrane was modified by coating binding agent polydopamine (PDA) graphene oxide (GO) using simple scalable inkjet printing process where the GO deposition controlled number of cycles. The test results revealed PDA-GO printed exhibited higher salt rejection while achieving slightly lower permeate flux compared to control membrane. Moreover, enhanced anti-fouling only 20% reduction observed displayed significant up 48%. Furthermore, showed effectively suppressed chlorination time 1 3 h. Our work demonstrates an effective strategy mitigate as well validate versatile technique formation advanced nanomaterial with high controllability properties.

Nanofiltration and Tight Ultrafiltration Membranes for Natural Organic Matter Removal—Contribution of Fouling and Concentration Polarization to Filtration Resistance

Nanofiltration (NF) and tight ultrafiltration (tight UF) membranes are a viable treatment option for high quality drinking water production from sources with high concentrations of contaminants. To date, there is limited knowledge regarding the contribution of concentration polarization (CP) and fouling to the increase in resistance during filtration of natural organic matter (NOM) with NF and ...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Preparation and Characterization of an Antifouling Polyethersulfone Nanofiltration Membrane Blended with Graphene Oxide/Ag Nanoparticles

Graphene oxide/Ag nanoparticles (Ag/GO) was prepared and employed to synthesize antifouling polyethersulfone (PES) mixed matrix membranes. The performance of the membranes was evaluated in terms of flux, hydrophilicity and anti-biofouling properties. With increment of the Ag/GO from 0 to 0.1 wt.%, the pure water flux increased from 24.7 up to 54.1 kg/m2 h. The flux recovery ratio (FRR) of the m...
