Globally, many people lack access to safe drinking water, and being that water-derived infections is a global cause for mortality, microorganisms that are resistant to disinfection must be removed. Although water-derived deaths […]

Even if we have a lot of water (71 percent of the earth’s surface), in some places on earth drinking water still remains an unsolved issue. Especially with the increasing population and industrial development, our clean water resources dropped drastically in recent years.
