FORWARD OSMOSIS WATER MAKING SYSTEM AND OPERATION METHOD OF FORWARD OSMOSIS WATER MAKING SYSTEM

Japanese Patent JP2017113675

A

PROBLEM TO BE SOLVED: To provide a forward osmosis water making system and an operation method of the forward osmosis water making system, in which a solute is suppressed to a minimum when mixing in a produced fresh water, a large scale distillation apparatus or a large scale solute dissolving unit is unnecessary, and energy consumption is small.SOLUTION: According to the embodiment, a forward osmosis water making system is provided, that includes a forward osmosis device having a forward osmosis membrane that partitions a supply liquid flow path through which raw water is supplied and a first absorption liquid flow path through which an absorption liquid containing a solute is supplied, a first heat exchanger, a first condenser, a second heat exchanger, and a gas-liquid separator. In the forward osmosis water making system, the first absorption liquid flow path, the first heat exchanger, the first condenser, the second heat exchanger and the gas-liquid separator are connected by a first absorption liquid line. The gas-liquid separator, the first heat exchanger,and the first absorption liquid flow path are connected by a second absorption liquid line. The gas-liquid separator and the first condenser are connected by a vapor line.SELECTED DRAWING: Figure 2
