Comparing Energy Recovery Devices: HPB Turbochargers vs Pelton Wheels

There are many benefits of replacing a Pelton Impulse Turbine with a Hydraulic Pressure Booster or HPB. Energy savings realized in the range of 6-20%. Total costs of HPB are typically 50% less than the cost of the Pelton Impulse Turbine. The HPB is much more compact and lower weight resulting in easier installation and maintenance.

This paper compares the cost factors of the Hydraulic Pressure Booster (HPB) energy recovery device manufactured by Fluid Equipment Development Company (FEDCO) with the Pelton Impulse Turbine (PIT) in seawater reverse osmosis (SWRO) applications.
