DRINKING WATER FROM DEEP SEA

Deep Sea Reverse Osmosis (DSRO) is a specialized water desalination process that uses reverse osmosis technology to produce fresh water, but instead of sourcing seawater near the shore, it taps into water from the deep ocean, typically at depths of 600 to 1,000 meters or more.

Advantages of DSRO

  1. Cleaner Source Water
    • Deep ocean water is very pure, with fewer organic materials, bacteria, and pollutants compared to surface seawater.
    • Less biofouling (clogging of membranes by organic matter), which improves membrane lifespan and lowers maintenance.
  2. Colder Water
    • Deep ocean water is naturally cold (~2–5°C), which helps in energy recovery and improves efficiency in certain system designs.
  3. Stable Quality
    • Surface seawater quality varies due to tides, runoff, or pollution, but deep ocean water is consistent in composition.
  4. Environmentally Friendly Intake
    • DSRO systems can use offshore intakes, reducing ecological disruption near coastal ecosystems.
