The SWPE energy recovery unit consists of an APP high-pressure 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.
The SWPE are available in sizes from 4-30 m3/day with recovery rates between 20%-32%. Other sizes are available upon request.
