“…The shrinkage proportion is under 60% in these membranes, which is more effective for filtration. [35] The performance of the synthesized membrane in water purification was measured by calculating their solvent content. Different solvents in polarity from propanol to water were selected to determine the solvent absorption capacity of the hybrid membrane.…”

Hybrid PVDF/PANI Membrane for Removal of Dyes from Textile Wastewater

et al. 2021

Treatment of textile wastewater has been a matter of considerable interest because of the potential toxicity, colloidal stability, and deformable nature of dyes. Herein, a novel polyaniline (PANI)/polyvinylidene fluoride (PVDF) hybrid membrane is developed to remove textile wastewater dyes. The hybrid membrane's contact angle decreases by increasing the concentration of polyaniline in the PVDF matrix, enhancing the hybrid membrane's hydrophilicity. Membrane properties, including porosity, antifouling property, solvent content, and pure water flux, are improved in the hybrid membrane compared with neat PVDF membranes. The purified water flux is enhanced from 28 to 47 L m−2 h, which indicates the impact of PANI on the hydrophilicity of the hybrid membranes. Among the hybrid membranes, 3P exhibits 85% dye rejection at 0.1 MPa operating pressure. Hence, the incorporation of PANI in the PVDF matrix is proposed to enhance the hybrid membrane's dye rejection and antifouling properties.

“…They used wet-phase inversion method with polysulfone and graphene nanoplatelets modified with poly (styrene) to obtain their membranes. ZnO was deposited on one surface of the membrane with polymers that are soluble in water [39]. In the study reported by Igbinigun and others, the modified GO-membrane showed 2.6 times better flux recovery compared to the unmodified membrane and this shows that it is wise to modify membrane with GO to increase flux recovery.…”

Wastewater and Water Quality

View full text Add to dashboard Cite

Water contamination by heavy metals, cyanides and dyes is increasing globally and needs to be addressed as this will lead to water scarcity as well as water quality. Different techniques have been used to clean and renew water for human consumption and agricultural purposes but they each have limitations. Among those techniques, membrane technology is promising to solve the issues. Nanotechnology present a great potential in wastewater treatment to improve treatment efficiency of wastewater treatment plants. In addition, nanotechnology supplement water supply through safe use of modern water sources. This chapter reviews recent development in membrane technology for wastewater treatment. Different types of membrane technologies, their properties, mechanisms advantages, limitations and promising solutions have been discussed.
