Sulfonated polyethersulfone/sulfopropyl methacrylate membranes impregnated with the polysulfopropyl acrylate coated ZnO nanoparticles were developed using a non-solvent-induced phase separation recipe. The composite offered much-enhanced hydrophilicity and improved porosity, which are critical for excellent antifouling performance high permeate flux. By adding modified ZnO, it achieved maximum ...

In this study, flat sheet asymmetric polyphenylsulfone (PPSU) ultrafiltration membranes with enhanced antifouling properties were prepared with a non-solvent induced phase separation (NIPS) method through compound additives containing a polymeric pore-forming agent, a small molecular non-solvent and a surfactant. The formation processes of the porous asymmetric membranes with different kinds of...

Porous permeable films materials have very broad prospects in the treatment of sludge-containing waste water due to their large surface area and good microfiltration. In this work, highly ordered porous membranes have been prepared successfully on ice substrates using a poly(phenylene oxide) (BPPO)-SiO₂ nanoparticle (NP) mixture by the brePorous permeable films materials have very broad prospec...

Application of nanoparticles as additives in membrane synthesis for improving the resistance of membranes against fouling has triggered recent interest in new membrane types. However, most nanoparticle-enhanced membranes suffer from the tradeoff between permeability and selectivity. In this study, nano-WS2 was explored as the additive in membrane synthesis by non-solvent induced phase separatio...

Graphene exhibits fascinating prospects for preparing high-performance membranes with fast water transport, due to its low friction and extreme thinness. However, graphene-assembled membranes, each molecule passing through the membrane should bypass many graphene sheets, which lengthens molecular pathways increases mass transfer resistance. Herein, a nanomesh (GNM) is fabricated that inspired b...

Water contaminated with low concentrations of pollutants is more difficult to clean up than that high pollutant content levels. Membrane separation provides a solution for removing from water. However, membranes are prone fouling, losing performances over time. Here we synthesized neutral (IM-NH2) and positively charged (IL-NH2) imidazole derivatives chemically functionalize membranes. With dis...

Organic fouling hinders the application of membrane treatment alternative water. In this study, polyethyleneimine (PEI), titanium dioxide (TiO2) nanoparticles, and graphene oxide (GO) nanosheets were used for modifying cation-exchange membranes to enhance anti-organic desalination performance during electrodialysis synthetical water municipal wastewater. Fouling propensity unmodified modified w...

Marine structures such as platforms, jetties and ship hulls are subject to diverse and severe biofouling. Methods for inhibiting both organic and inorganic growth on wetted substrates are varied but most antifouling systems take the form of protective coatings. Biofouling can negatively affect the hydrodynamics of a hull by increasing the required propulsive power and the fuel consumption. This...

Two coatings have been developed for petrochemical compressor antifouling and corrosion resistance purposes. One is a multilayer composite coating with a modified polytetrafluoroethylene (PTFE) impregnated organic topcoat, which gives it superior antifouling performance to the similar coating that has been used by the compressor original equipment manufacturers (OEMs). The other is a high-phosp...

The scarcity of freshwater resources in many regions the world has contributed to emergence various technologies for treating and recovering wastewater reuse industry, agriculture, households. Deep treatment from oils petroleum products is one difficult tasks that must be solved. Among known technologies, UF membranes have found wide industrial application with high efficiency removing pollutan...
