A concentration difference driven sea water desalination apparatus comprises a low pressure evaporating chamber, a pump, a pressure permeating tank and a plurality of tubes. The low pressure evaporating chamber may be arranged on the ground. The pump and the pressure permeating tank are disposed in a compartment under the low pressure evaporating chamber and connects to the tubes in series or communicates with the tubes. The apparatus may convert potential energy into kinetic energy to drive the pump to pump sea water for desalination purpose based on the salt concentration difference among various layers of sea regions, providing the advantage of energy saving.
