Abstract

The study investigated the effect of nanocomposites on water treatment. The modifications of sodium aluminum silicate hydrate by 3-bromo-5-chlorosalicylaldehyde to form a new composite. The synthesized composite was utilized for the removal of Acinetobacter baumannii cells from water samples. The maximum adsorption capacity of the synthesized composite towards Acinetobacter baumannii cells is 98.7%. These results suggest that nanocomposites could be a good adsorbent system for the removal of bacteria.The highest inhibition was at 50 % concentration. Acinetobacter baumannii were reduced in nanocomposite treated water sample, because of adsorption of bacteria on the nanocomposite surface.studies suggested physical disruption of bacterial membrane and oxidative stress as the major mechanisms. Therefore, the cells in contact with this nanomaterial were probably inactivated by one or both mechanisms.Nanocomposite is effective in treating microorganisms from water. These nanomaterials can be used to improve water quality and the availability and viability of water resources, such as through advanced filtration, which enables sustainable water reuse.
