SIRION™ Seawater

Complete package for seawater desalination

The SIRION™ Seawater reverse osmosis systems are specifically designed to treat seawater.

They reject over 99% of the salt contained within the feed water and include a flushing and chemical cleaning system which removes salt deposits, prevents scaling and maintains system performance.

  • From 25 to 890 m3/d
  • 16 models available
  • Feed water TDS up to 36000 ppm
  • Complete PLC control with touch screen interface
  • Raw water pump control & Multimedia pre-treatment filter control
  • 8" membranes
  • High pressure pump with Variable Frequency Drive (VFD) 
  • Energy recovery device, 35-55% energy saving
  • Limited maintenance

Flushing and chemical cleaning: The SIRION™ Seawater includes the Cleaning-In-Place (CIP) system to form a complete package and to avoid the contamination of the membranes and incrustation of minerals, organic matter, biological matter and colloidal particles.
