Comprehensive Analysis of Spinel-Type Mixed Metal Oxide-Functionalized Polysulfone Membranes toward Fouling Resistance and Dye and Natural Organic Matter Removal

Nanostructured polymeric membranes are of great importance in enhancing the antifouling properties during water filtration. Nanomaterials with tunable size, morphology and composition, surface

Removal of high concentration Congo red by hydrophobic PVDF hollow fiber composite membrane coated with a loose and porous ZIF-71PVDF layer through vacuum membrane distillation

Although membrane distillation (MD) technology has the outstanding advantages of almost 100% solute retention and mild operation conditions, its further development is limited by low permeate flux.

Removal of anionic dye Congo red from aqueous environment using polyvinyl alcohol/sodium alginate/ZSM-5 zeolite membrane

Experimental studies suggest that PVA/SA/ZSM-5 zeolite could be a promising candidate for the removal of Congo red from aqueous solution.

Removal of Congo red dye by ultrafiltration composite membrane of PpPD/PVA on flat pozzolan/micronized phosphate ceramic support

A new composite ultrafiltration membrane made of poly(p-phenylenediamine) and poly(vinyl alcohol) as a selective layer on flat ceramic support fabricated from pozzolan and micronized phosphate was

Preparation of a composite membrane made of PoPD/PVA ultrafiltration layer on ceramic pozzolan/micronized phosphate support for removal of Congo red dye

This work presents the development of a composite ultrafiltration membrane based on poly (o-phenylenediamine) and poly(vinyl alcohol) on flat ceramic support made from pozzolan and micronized

Comparative adsorption of anionic dye Congo red and purification of olive mill wastewater by chitin and their derivatives

In this study, chitin (CH), chitosan (CS) and epichlorohydrin cross-linked chitosan beads were applied to remove Congo red (CR) from an aqueous medium. The same materials were used for olive mill



Enhancement of antifouling properties using rice husk silica particles in polysulfone membrane and optimization of its operating condition

This study investigates the effects of rice husk silica (RHS) as additive in the polysulfone membrane to enhance antifouling properties in membrane separation process. The flat sheet PSf/RHS membrane

Effect of different additives on the fabrication of hydrophilic polysulfone ultrafiltration membranes

AbstractPolysulfone ultrafiltration membranes have been widely applied, especially for water and wastewater treatment. Polysulfone as membrane material presents several advantages, such as good

Investigating the Usability of Alkali Lignin as an Additive in Polysulfone Ultrafiltration Membranes

The effects of natural and synthetic polymer additives on the properties of ultrafiltration membranes were studied. The use of NaOH to remove the residual additive remaining in the membranes during

Probing the morphology and anti-organic fouling behaviour of a polyetherimide membrane modified with hydrophilic organic acids as additives

A facile approach for the preparation of an organic antifouling polymer membrane has been developed using low molecular weight organic acids as additives. The presence of these additives in the

Effect of various additives on pore size of polysulfone membrane by phase‐inversion process

The phase-inversion process was used to prepare integrally skinned asymmetric polysulfone (PSf) membranes with different pore sizes. Membranes were prepared from a casting solution of PSf;

Polysulfone–Chitosan blend ultrafiltration membranes: preparation, characterization, permeation and antifouling properties

Biocompatible and naturally occurring chitosan was used as an additive for the preparation of a polysulfone ultrafiltration membrane. Two different compositions of polysulfone in N-methylpyrrolidone
