“…Asymmetric cellulose acetate (CA) hollow fibre membranes hold a distant second spot [27]. Although the latter has superior chlorine resistance, thereby allowing prevention of the growth of microorganisms and algae via chlorine injection, the former has higher salt rejection and net pressure driving force [28]. There are four major membrane module suppliers which provide RO membranes for large scale desalination plants, namely DOW, Toray, Hydranautics and Toyobo.…”

Reverse osmosis (RO) is currently the most important desalination technology and it is experiencing significant growth. The objective of this paper is to review the historical and current development of RO membrane materials which are the key determinant of separation performance and water productivity, and to define the targets for those who are developing new RO membrane materials. The chemistry, synthesis mechanism(s) and desalination performance of various RO membranes are discussed from the point of view of membrane materials science. The review starts with the first generation of asymmetric polymeric membranes and finishes with current proposals for nano-structured membrane materials. The review provides an overview of RO performance in relation to membrane materials and methods of synthesis. To date polymeric membranes have dominated the RO desalination industry. From the late 1950s to the 1980s the research effort focussed on the search for optimum polymeric membrane materials. In subsequent decades the performance of RO membranes has been optimised via control of membrane formation reactions, and the use of poly-condensation catalysts and additives. The performance of the state-of-the-art RO membrane has been highlighted. Nevertheless, the advances in membrane permselectivity in the past decade has been relatively slow, and membrane fouling remains a severe problem. The emergence of nano-technology in membrane materials science could offer an attractive alternative to polymeric materials. Hence nano-structured membranes are discussed in this review including zeolite membranes, thin film nano-composite membranes, carbon nano-tube membranes, and biomimetic membranes. It is proposed that these novel materials represent the most likely opportunities for enhanced RO desalination performance in the future, but that a number of challenges remain with regard to their practical implementation.

“…CA membrane has a high chlorine resistance; hence, chlorine can be injected in the CA membrane unit to deter the growth of microorganisms and algae. On the other hand, RO/Nanoiltration (NF) has signiicantly higher salt rejection capacity and net pressure driving force potential [30]. Within the industrial sector, there are four primary membrane module suppliers that provide RO membranes to large-scale desalination plants, and these include DOW, Toray, Hydranautics, and Toyobo.…”

As water scarcity continues expanding in regions around the globe, there is an everincreasing need to augment municipal, industrial, and agricultural water supplies through the puriication of unconventional water sources, such as seawater, industrial and municipal wastewater. Due to the inextricable linkage between water and energy consumption, often called the water-energy nexus, the augmentation of water supplies must not come with a high cost energy consumption. As such, the high energy eiciency and often superior eicacy of membrane-based technologies have gained widespread implementation in various water treatment processes. Membranes allow passage of water, but largely reject salt and most other solutes, play a critical role in the majority of these processes. These types of membranes lie at the heart of traditional reverse osmosis (RO) processes.
