PURPOSE: A spiral type membrane distillation module is provided to be able to prevent heat loss, thereby being able to minimize the heat energy waste by directly heating inflow water within the module. CONSTITUTION: A spiral type membrane distillation module (100) comprises a central tube (110); and a membrane leaf (120) wound along the outer periphery of the central tube in a spiral shape. The membrane leaf is composed by laminating a treated water passage, a membrane, an inflow water passage, and a heater. The central tube has a penetration part in one area. |
