A model of design is provided in order to determine the most effective processes to fabricate and test a 2D Membrane for its effectiveness in water desalination. Water desalination with a 2D Membrane has already shown great theoretical results due to its energy efficiency that results from the thinness of the membrane. The 2D Membrane to be used in the model of design is Molybdenum Disulfide (MoS2) due to its thickness of 3 atoms and Molybdenum’s hydrophilicity. The need for water desalination is important, especially with the increased salt concentration in saline water. Current desalination plants cannot currently filter saline water. The process to be covered includes first fabricating the MoS2 into 2D membranes (mono layered sheets), transferring the 2D sheets onto a predesigned suspension system, drilling a pore in the membrane in order to allow water to flow through, and setting up a forward osmosis process to evaluate the effectiveness of the membrane in desalinating saline water.
