About a decade ago, researchers started investigating the use of nanotechnology towards water processing and purification. The general size of the nanotechnology based water filtration products are smaller than traditional devices which leads to concerns regarding use and maintenance. Recently, graphene and plasma based devices and have also been investigated in a variety of areas of water purification. Research by Nobel Prize winner Andrei Geim with Rahul Nair has indicated that defects in graphene oxide result in a barrier that is highly impermeable to everything except water vapor. Additionally, plasma has been used to chemically treat water to reduce the number of harsh chemicals as well as destroy bacterial and viral organisms. The combination of these two technologies can be useful in water filtration applications. The following work deals with the development of a low cost graphene and plasma based hybrid water purification systems towards removal of organic water and salt based contaminants.
