Seawater Desalination Based on a Bubbling and Vacuum-Enhanced Direct Contact Membrane Distillation

Figure 1

Flow chart of the seawater desalination process based on BVDCMD. T₁∼T₆: the temperature of feed inlet, feed outlet, permeate outlet, permeate inlet, and inlet and outlet of heat exchanger 2, respectively. P₁∼P_3: the pressure of freshwater, seawater, and gas. Q₁∼Q_5: the flow rate of feed inlet, feed outlet, permeate inlet, permeate outlet, and gas inlet.
