<P>PROBLEM TO BE SOLVED: To provide a water making system by a membrane distillation, by which freshwater can be recovered from seawater or others without needing burdensome operation with simple facilities comprising simple structure and running cost is low. <P>SOLUTION: The water making machine has a liquid phase part through which treating water flows, a gas phase part in air tight condition, a vaporizing part comprising a hydrophobic porous membrane dividing the liquid phase part and the gas phase part, a condensation part in higher pressure than the gas phase part, a pump blowing air in the gas phase part to the condensation part, and a liquid sending means sending the treating water to the liquid phase part. Water in the treating water is taken out as vapor in the gas phase part, is condensed in the condensation part, and is recovered as the water. <P>COPYRIGHT: (C)2012,JPO&INPIT |
