Desalination Performance of Nano porous Mos Membrane on Different Salts of Saline Water: A Molecular Dynamics Study
The freshwater crisis is a growing concern and a pressing problem for the
world because of the increasing population, civilization, and rapid industrial
growth. The water treatment facilities are able to supply less than 1% of the
total water demand. Water desalination can be a potential solution to deal with
this alarming issue. Researchers have been exploring for quite some time to
find novel nano-enhanced membranes and manufacturing techniques to increase the
efficiency of the desalination process. Graphene and graphene modified
membranes showed huge potential as desalination membranes for comparatively
easier synthesis process and higher ion rejection rate than conventional filter
materials. Currently, single-layer Mos has been discovered to have the same
potential of water permeability and ion rejection rate as graphene membrane in
a more energy-efficient way. For almost analogous nano porous structure of the
graphene membrane, almost 70% of the higher water flux is obtained from the
Mos membrane. In this work, it has been shown that nano porous Mos
membranes provide a promising result for desalinating other salts of seawater
alongside NaCl. We have also observed the effect of variations in ions, pore
size, and pressure on water permeation and ion rejection rates in the water
desalination process. In this study, water permeation increased significantly
by increasing the pore area from 20{\AA} to 80{\AA}. The rate of water
filtration increases in proportion to both applied pressure and pore size,
sacrificing the ion rejection rate for the type of ions studied. A combination
of salt ions in the saline water for desalination has also been studied, where
the rejection rates for the different ions are separately represented for
various applied pressures. For seawater, the Mos membrane has showed quite
promising performance in the study of ion variation
