A Review of Nanotechnology Application for Seawater Desalination Process. SOIJST Vol. 1 (1):155-179

Abstract

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.

Effective removal of proteins using carbon‐based nanoadsorbent: relevancy to the application of membrane‐driven pre‐water treatment

“…Recent advances in nanotechnology have led to the development of new multifunctional nanomaterials with excellent adsorption capacity for proteins and heavy metals with inherent antimicrobial activity that might be suitable for pre-treatment of wastewater before membrane and biological treatment. [13][14][15][16][17][18][19] Such nanomaterials have the potential for preventing organic fouling resulting from the deposition of protein over the membrane surface as well as its biofouling, along with reducing the oxygen requirement during tertiary biological treatment of wastewater. 12 Graphene oxide (GO) has been demonstrated as one of the most promising nanomaterials, having a large surface area and multiple functional groups that find various applications in biomedicine, 20,21 and environmental applications such as wastewater treatment.…”
