Applications

Applications

  • Auxiliary applications
    The complex processes performed on a typical FPSO rely on the performance of dozens of pumps handling a variety of liquids under widely varying process conditions.

  • Auxiliary services
    In each desalination plant there is a number of pumps providing auxiliary services at the different stages: filter backwash, membrane flushing, membrane cleaning, etc. Due to lower head and flow requirements, typically theses auxiliary services will require end suction, single stage pumps.

  • Municipal clean water supply and distribution
    Getting drinking water to all parts of a distribution network involves many challenges along the way. From the water treatment plant through pumping stations and beyond, Sulzer pumps lift and move the drinking water to bring it to its destination at sufficient flow and pressure.

  • Pre-treatment
    Before reaching the RO Island, where specifically the desalination process will take place, raw water needs to be treated to ensure the required quality of the raw water to avoid fouling the RO membranes.

  • RO-Island HPP 2nd pass
    This is the heart of the SWRO desalination process, where the desalination effect takes place. The treated sea water is fed by means of the high pressure pumps into the RO membranes, obtaining permeate or product water and high pressure brine rejection, whose high pressure energy is recovered by selected Energy Recovery Device.

  • Water intake
    Raw water to be desalted, either sea water or brackish water will be taken from natural resource and pumped to pre-treatment stage. For sea water abstraction, different intake arrangements can be considered, which will define the pump type to be installed.
