Equipment specifications vary widely, with power consumption ranging from a few kilowatts in small-scale units to several hundred kilowatts for large offshore desalination plants. Flow capacities can span from 1,000 liters per day for residential systems to over 1,000 cubic meters per hour for industrial-scale applications.

3. The Role of Reverse Osmosis in Seawater Desalination Systems

In offshore and maritime contexts, freshwater availability is often limited and costly. Reverse osmosis system water technology reliably converts high-salinity seawater into potable water, meeting stringent safety and quality standards. The salt concentration in seawater (~35,000 mg/L) is reduced to below 500 mg/L, often near 200 mg/L, delivering water suitable for human consumption and industrial processes.

Operational advantages of RO desalination include:

• Compact footprint and modular scalability for shipboard or platform installation.
• Low chemical usage compared to thermal distillation methods.
• Energy recovery technology integration, such as pressure exchangers, significantly reducing the overall energy demand.
• High reliability and automated controls ensuring consistent water quality despite fluctuating feed water conditions.

4. Global Water Resource Challenges and the Strategic Importance of Desalination

The world faces an increasing freshwater shortage driven by population growth, urbanization, agriculture intensification, and climate change. Conventional freshwater sources are under pressure, with over two billion people experiencing water stress. Desalination via reverse osmosis system water has emerged as a strategic solution, particularly for water-scarce coastal and island regions.

Technological advances and cost reductions have accelerated adoption worldwide. Projections estimate the global RO market will reach nearly $15 billion by 2034, reflecting substantial investments in capacity expansion. Seawater desalination enables stable freshwater supplies for drinking, industrial processes, and agriculture, underpinning economic growth and social welfare in remote or arid zones.

5. Technological Innovations Driving Performance and Efficiency

Recent breakthroughs have reinforced RO system advantages while mitigating traditional drawbacks such as high energy consumption and membrane fouling. Notable innovations include:

• Advanced Membrane Materials: New composite membranes exhibit enhanced salt rejection, fouling resistance, and mechanical durability, extending operational lifetime and lowering replacement costs.
• Energy Recovery Devices: Integration of isobaric devices like pressure exchangers has slashed energy use by up to 60% in some plants.

6. Technical Principles of Seawater Desalination via Reverse Osmosis

The reverse osmosis process harnesses hydraulic pressure to push seawater across semi-permeable membranes, separating freshwater from dissolved salts. The key stages are:

1. Pre-Treatment: Removing suspended solids and organic materials prevents membrane fouling and extends membrane life.
2. High-Pressure RO Filtration: Feed water is pressurized typically between 50–80 bar, overcoming osmotic pressure to drive water molecules through membranes while rejecting salt ions and contaminants.
3. Post-Treatment: The permeate (clean water) undergoes pH balancing, disinfection, and mineral supplementation, ensuring compliance with drinking water standards.

This multi-step approach is critical for delivering high-purity water. Membrane technology has evolved to achieve salt rejection rates exceeding 99%, coupled with operational stability. Effective brine management is also essential for environmental compliance.

7. Expanded Application Scenarios: Offshore and Harsh Environment Usage

Reverse osmosis system water solutions are not confined to land installations.
