Japanese Patent JP2018153799
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce heating costs by using a heat pump to heat water supplied to a reverse osmosis membrane device.SOLUTION: Raw water is supplied from piping 1 to a heat exchanger 2 and heated, and then water vapor from piping 3 is supplied to a heat exchanger 4 as a heat source, further heated, and then supplied to an RO device 6. Permeated water from the RO device 6 is taken out from piping 7 as treatment water, and concentrated water flows out to piping 8 and passes to an evaporator 11 of a heat pump 10 as a heat source fluid of the heat pump 10. Medium water heated by a condenser 13 of the heat pump 10 is circulated in a heat source fluid flow path in the heat exchanger 2.SELECTED DRAWING: Figure 1
