Design and development of a Nanomembrane for filtering arsenic from drinking water

Abstract

In rural areas the contamination of drinking water with heavy metals such as Arsenic, Cadmium, Lead and Mercury due to agricultural fertilizers and chemicals poses a significant health risk. Arsenic, in particular, is known to cause severe kidney problems and has a high impact on cancer incidence. According to the previous literature adsorption, ion exchanges, electrokinetic processes, electrocoagulation, chemical precipitation, phytoremediation, nano phytoremediation, membrane technology and phytobial remediation are the methods that have been used in removing arsenic from water. To address this critical issue this project focuses on developing advanced nanomembrane technology specifically designed to filter out arsenic from drinking water. Nanomembrane technology is highly effective and suitable for use in as other existing methods are time consuming, cost-prohibitive and sludge forming while these nanomembranes(NM) depicts higher specific area, nanoporous structure, easy tuneable surface functionalities and affordable. This technology will enhance the filtration process by removing arsenic ion from the drinking water.
