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

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.

2.Key features

• Designed for any size reverse osmosis desalination plant
• 98% efficiency
• Scalable solution for our customers who need premium performance energy recovery with a larger unit capacity
• Lowest lifecycle cost of any energy recovery device on the market

4. Applications

• Seawater RO plant, seawater desalination equipment, seawater reverse osmosis system
• Oil drilling rig
• Landfilled leachate treatment
• Fire extinguisher (extinguishing) system spray
• Sepcial separation RO membrane system
• Other membrane system for highly TDS water treatment

​6. Competitive advantage

This rotor energy recovery coaxial boosting device is made of anti corrosion Super Duplex which provides unmatched durability in even hardest working condition. The simplicity and modularity of this design allows for optimum scalability, quick startup, and no required maintenance. The PI series Pressure Exchanger device captures hydraulic energy from the high pressure reject stream of seawater reverse-osmosis processes and transfers this energy to low pressure feed water with over 95% efficiency.
