Abstract: A water treatment system includes a reverse osmosis membrane device, an electrodeionization device that is located downstream of the reverse osmosis membrane device, a first heat exchanger that is located upstream of the reverse osmosis membrane device and that adjusts the temperature of the water supplied to the reverse osmosis membrane device according to the temperature of raw water supplied to the water treatment system, and a second heat exchanger that is located between the reverse osmosis membrane device and the electrodeionization device and that cools the water supplied to the electrodeionization device. One of the first heat exchanger and the second heat exchanger is an internal heat exchanger that exchanges heat inside the water treatment system, and the other is an external heat exchanger that exchanges heat with the outside of the water treatment system.
