Emergency seawater desalination units

Emergency seawater desalination units 2000L/h

Emergency seawater desalination unitsIn case of natural disaster or war, well water or surface water can be quickly contaminated by human wastes. Seawater becomes the safest solution.

When seawater is available it provides the safest and most reliable water source compared to surface or underground water

  • Less risk of cross contamination from destroyed sewage pipes, dead bodies
  • Endless water availability
  • Easy to find water source
  • Easy waste disposal: brine goes back to sea
  • Less concentrated effluent due to lower process recovery

Lenntech has designed ready-to-use skid mounted desalination plants that can produce up to 2 m3/h of drinking water according to WHO standards.

Our systems are manually to fasten the start up and ease operation


  • Seawater resistant self priming feed pump with intake strainer
  • Multi-media filtration at low velocity with manual multi valve
  • 5-micron police cartridge filter
  • High pressure pump
  • High quality seawater RO membranes (Filmtec or Hydranautics)
  • Manual Cleaning In Place (CIP) station
