<p>A dehydrator using gravity, mechanical compression, electroosmosis is proposed. The dehydrator includes: a gravity dewatering unit dewatering sludge by gravity; a press dewatering unit that is disposed at an outlet of the gravity dewatering unit and presses and dewaters the sludge subjected to the gravity dewatering; and an electroosmotic dewatering unit dewatering the sludge and including an electric drum that is disposed at an outlet of the press dewatering unit and relays or induces current to the sludge,and a caterpillar that is isolated from the electric drum by an insulator disposed along an outer circumference of the electric drum and has a side pressing and contacting the outer circumference of the electric drum.</p> |
