“…Although Ag concentration that meet drinking water quality standards is not determined by WHO or other water regulating authorities, immobilized Ag can be a good alternative as disinfectant because of higher surface area to volume ratio and its tremendous antimicrobial properties (Hossain, et al, 2014). Ceramic filter and Membrane or paper impregnated Ag nanoparticles can be applied in POU (point-of-use) water treatment process in case of emergency (Dankovich TA, 2011).…”

“…Furthermore, Ag nanoparticles can enhance the inactivation efficiency while reducing the time and nano disinfectant requirement for a system (Hossain, et al, 2014). The practical application of nanoscale silver, however, is limited by probable side-effects caused by the release of nanoscale silver particles and/or dissolved Ag species in water, which would play a detrimental effect on the impacted aqueous environment.…”

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.

RESUMENLa dispersión de nanopartículas antibacterianas en matrices poliméricas biocompatibles, no tóxicas y biodegradables permitirá el desarrollo de materiales más eficientes y efectivos para la conservación de alimentos, la eliminación de contaminantes y la protección contra microorganismos que comprometen la salud humana. Los materiales bactericidas nanométricos tienen una relación superficie / volumen muy grande que les permite interactuar con más copias de moléculas biológicas, y por lo tanto, mejorar la eficacia antimicrobiana. Más recientemente, se ha sugerido la actividad antimicrobiana del MgO amigable con el medio ambiente y químicamente estable. La incorporación de compuestos bactericidas en una matriz polimérica puede combinar la estabilidad física proporcionada por la matriz polimérica con las propiedades antimicrobianas de los agentes antimicrobianos dispersados como partıculas pequeñas sólidas. Sobre esta base, la presente investigación se centrará en el desarrollo de mezclas de partículas inorgánicas poliméricas biocompatibles, los denominados nanocompuestos, con actividad antimicrobiana sintonizable y mejorada. Se confirmó la actividad antimicrobiana de perlas de alginato cálcico -MgO (que oscilaban entre 0% y 40% p / p MgO) contra E. coli. Las perlas que contenían 20% p / p de MgO inhibían completamente el crecimiento bacterial de la E. coli ABSTRACTThe dispersion of antibacterial nanoparticles into bio-compatible, non-toxic and bio-degradable polymeric matrices will enable the development of more efficient and effective materials for food preservation, removal of contaminants, and protection against human health-compromising microorganisms. Nanometric bactericidal materials have a very large surface to volume ratio that enable them to attach more copies of biological molecules, and hence, enhance antimicrobial efficiency. More recently, the antimicrobial activity of environmental-friendly and chemically stable MgO has been suggested. The incorporation of bactericidal compounds into a polymeric matrix can combine physical stability provided by the polymeric matrix with the antimicrobial properties of antimicrobial agents dispersed as solid tiny particles. On this basis, the present research will be focused on the development of biocompatible polymer-inorganic particle mixtures, so-called nanocomposites, with tunable and enhanced antimicrobial activity. The antimicrobial activity of calcium alginate -MgO beads (ranging from 0% -40% w/w MgO) against E. coli was confirmed. Beads containing 20% w/w of MgO fully inhibited the E. coli. bacterial growth.

“…It decomposes dissolved organic impurities under UV irradiation (Colmenares et al, 2015) and exhibits antibacterial effects (Hossain et al, 2014), in particular in the case of E.coli and S.aureus (Jaisai et al, 2012). At the same time ZnO is considered safe to people, being added to breakfast cereals and nutrition drinks.…”

Hybrid filter material was obtained via modification of polypropylene (PP) nonwoven with nanosize zinc oxide particles of a high aspect ratio. Modification was conducted as a three-step process, a variant of hydrothermal method used for synthesis of nano-ZnO, adopted for coating three dimensional polymeric nonwoven filters. The process consisted of plasma treatment of nonwoven to increase its wettability, deposition of ZnO nanoparticles and low temperature hydrothermal growth of ZnO rods. The modified nonwovens were investigated by a high resolution scanning electron microscopy (HR-SEM). It has been found that the obtained hybrid filters offer a higher filtration efficiency, in particular for so called most penetrating particle sizes.
