<p><P>PROBLEM TO BE SOLVED: To provide a purified water feed device capable of producing purified water while suppressing its operating cost. <P>SOLUTION: A pressure feed pump 32 for feeding raw water to a water purification apparatus 30 having a reverse osmosis membrane 31 under pressure is driven by the electric power generated by a thermoelectric cogeneration apparatus 20, and raw water fed to the water purification apparatus 30 is heated to a prescribed temperature by waste heat from the thermoelectric cogeneration apparatus 20. The warm water purified by the water purification apparatus 30 exchanges heat with raw water before heating to preheat the raw water, and simultaneously to obtain purified normal temperature water. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
