An Overview of Photocatalytic Membrane Degradation Development

Abstract

Environmental pollution has become a worldwide issue. Rapid industrial and agricultural practices have increased organic contaminants in water supplies. Hence, many strategies have been developed to address this concern. In order to supply clean water for various applications, high-performance treatment technology is required to effectively remove organic and inorganic contaminants. Utilizing photocatalytic membrane reactors (PMRs) has shown promise as a viable alternative process in the water and wastewater industry due to its efficiency, low cost, simplicity, and low environmental impact. PMRs are commonly categorized into two main categories: those with the photocatalyst suspended in solution and those with the photocatalyst immobilized in/on a membrane. Herein, the working and fouling mechanisms in PMRs membranes are investigated; the interplay of fouling and photocatalytic activity and the development of fouling prevention strategies are elucidated; and the significance of photocatalysis in membrane fouling mechanisms such as pore plugging and cake layering is thoroughly explored.

The function of microbial enzymes in breaking down soil contaminated with pesticides: a review

“…As an example, Vitola et al proposed the biocatalytic membrane reactor that was based on covalently immobilizing a triple mutant of the SsoPox on polymeric membranes. The study outcome showed significant paraoxon degradation and long-term stability of the free enzyme [ 59 ]. Other PLLs, such as that derived from Geobacillus kaustophilus (GkaP), have been found to have capability as OP-degrading enzymes.…”

Effect of Chitosan-TiO2 Membrane Performance for the Degradation of Batik Waste with a Photocatalytic Hybrid System

“…The uniform distribution of TiO2 particles and strong bonding between TiO2 and the chitosan matrix are crucial for maintaining membrane stability during the photocatalysis process and enhancing pollutant degradation efficiency. The advantage of the Chitosan-TiO2 membrane in this hybrid photocatalytic process is its ability to integrate the filtration process with photocatalytic treatment (Hashemi & Lai, 2023), making batik wastewater treatment more efficient in a single step. This reduces the use of hazardous chemicals in the wastewater treatment process and produces wastewater that is safer for the environment.…”

Application of coal fly ash based ceramic membranes in wastewater treatment: A sustainable alternative to commercial materials

“…Membranes are primarily categorized into organic (polymeric) and inorganic (ceramic) types [ 16 ]. Organic membranes are those that are made up of nonporous polymeric materials, such as cellulose acetate, polyethersulfone, polyimide, polysulfone, polymethylpentene, polycarbonate, polydimethylsiloxane, and polyphenylene oxide [ 19 , 20 ]. Ceramic membranes are fine artificial porous membranes made from sintering inorganic materials, such as alumina, zirconia oxide, titanium, silicon oxide, silicon carbide, and silicon nitride or a combination of these materials under high temperatures [ 21 , 22 ].…”
