Solving the global water crisis using deep ocean water

By 2030, global freshwater water demand will exceed supply by 40%. We have abundant amounts of seawater available for freshwater production through Seawater Reverse Osmosis (SWRO). However, conventional SWRO plants are large and power-hungry. And due to high biological activity in the surface intake water, 60-70% of a SWRO plant is pre-treatment processes. These involve use of chemicals which later follow the salty, brine-stream back into surface waters, negatively affecting corals and other marine organisms.

There is another way.

Using predictably clean seawater at depths where sunlight does not reach. Where water is naturally pressurized to 40 to 50 bar, ideal for SWRO.

Enter FSubsea, a team based in Oslo, Norway who has deployed more than 50 subsea pumping systems. A team that helped develop the world’s first subsea water treatment plant (NOV's "Seabox").

This team is now launching the FLOCEAN (flow-from-the-ocean) subsea SWRO desalination system harnessing the natural qualities of the deep ocean. Leveraging Norway's 5 decades of experience with subsea equipment, the team uses unique skills, proven technology and is cooperating closely with global water leaders.

- Low energy (40-50% less than conventional RO)
- Affordable
- Chemical-free
- Storm resilient
- No harm to the marine ecosystem

Is the 40-50% increase in efficiency compared to on-shore desalination for the time of installing the system or during the entire life of the system?

Isn't the cost of the water transfer system and pumping from the deep ocean to residential areas more than the efficiency of this system?

This is not a new idea
and was abandoned because the idea wasn't recognized as an optimal design in the past.
