PROBLEM TO BE SOLVED: To provide an energy recovery apparatus capable of constituting a chamber using an inexpensive ready-made article having a large flow amount and an inside diameter of 8 inches (200 mm) or less while making use of the characteristics of a piston-free type energy recovery chamber and capable of increasing a treating flow amount.SOLUTION: An energy recovery apparatus comprises: a plurality of cylindrical chambers 20-1, 20-2 and 20-3 having spaces to store concentrated seawater and seawater inside and arranging longitudinal directions to be vertical; concentrated seawater ports P1 being arranged at the lower part of each chamber and supplying and discharging the concentrated seawater; seawater ports P2 being arranged at the upper part of each chamber and supplying and discharging the seawater; and concentrated seawater supplying and discharging valves 6 connected to the concentrated seawater ports supplying and discharging the concentrated seawater. In the concentrated seawater supplying and discharging valves 6, supplying and discharging ports CP are branched and connected to the concentrated seawater ports P1 of a plurality of the chambers 20-1, 20-2 and 20-3. |
