High pressure exchanger for energy recovery in seawater RO plant 95% efficiency

1.  Description of Rotor energy recovery coaxial boosting device

This pressure exchanger device has been widely applied in high TDS seawater, waste water, landfill leachate RO treatment system. It adopts "Rotor energy recovery coaxial boosting technique" to realize energy recovery and pressure increase, it transfer the high pressure energy from the concentrate flow from reverse osmosis system to low pressure raw feed water, so the raw feed water pressure has been increased to high pressure, then pressure boosted by impeller pump to meet pressure requirement for seawater RO plant, it reduce raw water flow to high pressure pump, hence save energy consumption. This pressure exchanger device can help significantly reduce operation cost of seawater desalination RO plant, minizie the interconnecting piping, valves and instruments requirement, simiplize the high pressure piping design for energy recovery device, easily and space saving.
