“…5 depicts the new concept of embedding molecular sieve nanoparticles in the top selective layer in the preparation of thin film nanocomposite (TFN) membrane. The new concept was first started by Hoek et al [48] in early 2007. In their pioneering work, it is experienced that the super-hydrophilic and negatively charged zeolite-A embedded throughout PA thin film was able to dramatically improve the permeability of the TFN membrane and remained equivalent salt rejection when compared with the pure PA composite membrane.…”

As freshwater resource decreasing rapidly due to high rate of human population growth, many researchers have done studies to develop methods for producing freshwater supply. Seawater desalination is one of the method that has the credibility to be implemented. However, conventional seawater desalination processes suffer from a number of problems related to energy efficiency and cost. In spite of this, nanotechnology has been applied to the process. In this paper, we give an overview and explanations concerning the roles of nanotechnology in seawater desalination processes which consist of pretreatment, reverse osmosis (RO), and disinfection. In addition, the comparisons between conventional and nanotechnology-applied processes as related to its efficiency and effectiveness are also provided.

“…Thin film nanocomposite membrane has become a frequently selected RO membrane [6].This membrane is prepared by interfacial polymerization (IP) process and incorporation of nanoparticles into polyamide (PA) active layer with the aim of improving membrane characteristics including the hydrophilicity and surface charge. The term TFN membrane was first introduced by Hoek and his coworkers in 2007 [7]. In their work, they used zeolite NaA nanoparticles as filler in PA active layer during interfacial polymerization between m-phenylenediamine (MPD) and trimesoyl Chloride (TMC).…”
