    Carbon-based nanocomposite membranes for water and wastewater purification
    (Elsevier, 2018) Gnani Peer Mohamed, G.P.S.; Isloor, A.M.; Yuliwati, E.; A.F., A.F.
    The carbon-based nanocomposite membranes are developing core technology for water and wastewater purification. These materials are broadly used in the fabrication of ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO) and evolving forward osmosis (FO) nanocomposite membranes as an additive. In this chapter, performance enhancement of nanocomposite membranes using carbon nanotubes (CNTs) and graphene oxide (GO), especially in the field of desalination, dye removal, oil/water separation and natural organic matter removal, is discussed. © 2019 Elsevier Inc.

    Synthetic polymer-based membranes for dye and pigment removal
    (Elsevier, 2020) Gnani Peer Mohamed, G.P.S.; Isloor, A.M.; Lakshmi, B.
    The use of synthetic polymeric membranes to remove dyes and pigments from industrial wastewater is a growing technology. The toxic and nonbiodegradable nature of dyes and pigments in industrial wastewater influences the importance of the removal of those dyes and pigments. Conventional methods such as coagulation, the photocatalytic process, adsorption, ozonation, plasma treatment, electrochemical treatment, etc., are proposed. However, these methods are very time-consuming, use expensive catalysts, are difficult to scale up, and need secondary treatment. In recent times, a substantial number of attempts have been put forward to advance the performance of polymeric membranes for dye and pigment wastewater treatment. In this chapter, the recent progress on the use of polymeric membranes in processes such as nanofiltration, membrane distillation, and ultrafiltration for effective dye and pigment removal are discussed. © 2020 Elsevier Inc.

    Advances of membrane technology in wastewater treatment
    (Elsevier, 2024) Deepthi, P.V.; Viji, K.; Vijesh, A.M.; Isloor, A.M.; Kumar, V.
    Pure water scarcity is becoming a real threat to the modern world. Rapid growth in the textile, paper, and printing industries has caused the production of large quantities of dye effluents, and they must be treated before passing to the water bodies or lands to minimize pollution and environmental impacts. Polymeric membrane-based filtration has been established as an optimal and greener approach for removing hazardous dyes from polluted water. Superior thermal, chemical, and mechanical properties and convenient modifiability made polysulfone (PSF), polyethersulfone (PES), and polyphenylsulfone (PPSU) ideal for the production of membranes for the treatment of dye effluents from industries. This chapter emphasizes the recent developments in modified PSF, PES, and PPSU membranes and their dye rejection properties. © 2025 Elsevier Inc. All rights reserved.
