Seawater Pump With Energy Recovery Type SWPE

Seawater Pump With Energy Recovery Type SWPE

The Danfoss SWPE is a high-efficiency energy recovery unit for reverse osmosis filtration of sea water. Energy recovery is achieved by feeding high-pressure brine from membranes into the recovery device (APM) that converts the energy in the pressurized brine into mechanical energy for reuse by the electric motor.

Design:

The SWPE energy recovery unit consists of an APP pump and an APM motor, both connected to a double-shafted electric motor.The permeate flow and recovery rate depend on the difference between the size of an APP and an APM, as they have a fixed volumetric displacement.

Energy recovery is obtained when high-pressure brine from the membranes is fed to the APM that converts the energy in the pressurized brine to mechanical energy to be re-used by the electric motor. As the APM has a fixed volumetric displacement, the recovery rate will be fixed.

Capacity:

SWPE are available in sizes from 4-30 m3/day with recovery rates between 29-32%. Other sizes are available upon request.
