    Reverse osmosis pretreatment techniques, fouling, and control strategies
    (Elsevier Inc., 2019) Gnani Peer Mohamed, G.P.S.; Isloor, A.M.; Farnood, R.
    In recent times, many commercial-scale seawater desalination plants have been constructed in water-stressed countries, which are expected to increase in the near future to increase the availability of potable water. In spite of many developments in the desalination technologies, seawater desalination using reverse osmosis (RO) membrane is being considered as the state-of-the-art technology. However, there are also some limitations to the RO membrane desalination such as the unavoidable membrane fouling, which increase the operating cost and transmembrane pressure. Here, we review the potential way to the RO membrane fouling control strategies, which includes the role of advanced materials, surface modification and feed water pretreatment that are emphasized based on the extensive up-to-date literature. © 2020 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.
