Abstract:

Membrane fouling is a major drawback in the membrane filtration industry for water treatment. Mixed-matrix membranes (MMMs) are well known for their enhanced antifouling and antibacterial properties, which could offer potential benefits for membrane filtration processes in the water treatment field. In this work, three electrospun nanofibrous MMMs (P, CP, and MCP, which were, respectively, the pristine polysulfone membrane and mixed-matrix membranes (MMMs) consisting of GO–ZnO and GO–ZnO–iron oxides) were studied for antifouling and antibacterial properties with respect to the arsenic nanofilt

Abstract:

Water shortage is a major worldwide issue. Filtration using genuine polymeric membranes demonstrates excellent pollutant separation capabilities; however, polymeric membranes have restricted uses. Nanocomposite membranes, which are produced by integrating nanofillers into polymeric membrane matrices, may increase filtration. Carbon-based nanoparticles and metal/metal oxide nanoparticles have received the greatest attention. We evaluate the antifouling and permeability performance of nanocomposite membranes and their physical and chemical characteristics and compare nanocomposite membranes to b

Abstract:

In general, the polysulfone (PSf) membranes are popular choices for water treatment because they have high thermal stability and good chemical resistance. On the other hand, the filtration capacity of the polysulfone membrane is limited because of its low water flux and poor antifouling ability, which are caused by the low surface hydrophilicity of the membranes. In this research, blending of graphene oxide (GO) or graphene oxide-titanium dioxide (GO-TiO2) mixture into the polysulfone matrix had been carried out through the phase inversion method to enhance the hydrophilic and antifouling prop

Membrane technology is an essential tool for water treatment and biomedical applications.

Abstract:

Membrane-based separation has gained increased popularity over the past few decades, particularly reverse osmosis (RO). A major impediment to the improved performance of membrane separation processes, in general, is membrane fouling. Fouling has detrimental effects on the membrane’s performance and integrity, as the deposition and accumulation of foulants on its surface and/or within its pores leads to a decline in the permeate flux, deterioration of selectivity, and permeability, as well as a significantly reduced lifespan. Several factors influence the fouling-propensity of a membrane, such

Abstract:

Industries in Indonesia significantly contribute to the economy by increasing foreign exchange earnings and creating job opportunities. However, industrial activities also negatively impact the environment, particularly water pollution caused by liquid waste containing oil emulsions. This research aims to develop a membrane based on cigarette filters as an alternative to cellulose acetate for separating oil emulsions in water. Cigarette filters were processed into membranes with tannic acid (TA) and ferric chloride (FeCl3) as additives using a vacuum-filtration coating technique. The resulting

Abstract:

Reverse osmosis and microfiltration are two membrane-based separation techniques that have gained popularity over the past few decades. A fundamental barrier to improving the overall efficiency of membrane separation is membrane fouling. The accumulation of foulants causes a reduction in permeate flux, a loss of selectivity and permeability, and a reduction in the membrane’s lifespan. Numerous chemical and physical surface changes have been studied to enhance membrane antifouling properties. Additionally, research has concentrated on creating membranes that use cutting-edge materials to improv
