Item 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. All rights reserved..Item Fundamentals and basics of reverse osmosis(Elsevier Inc., 2019) Gnani Peer Mohamed, G.P.S.; Isloor, A.M.; Farnood, R.This chapter endows an inclusive introduction to the fundamentals and basics of the reverse osmosis (RO) process. It starts from the short history, plants, and theoretical contextual of RO. A concise summary of the recent advances in RO membranes and materials then follows. Lastly, the usage of different types of modules such as spiral wound prepared from flat sheet membranes and hollow fiber membranes used in RO desalination is discussed. © 2020 Elsevier Inc.

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.
