Marine Water Purification Systems | RO Desalination Equipment
Intro: Facing freshwater scarcity? Our seawater reverse osmosis systems transform ocean water into high-quality drinking water. Advanced SWRO technology delivers 99.4% salt rejection with energy consumption as low as 1.8 kWh/m³.
Global Water Crisis & SWRO Solution
The Challenge:
- Freshwater resources continue to diminish globally
- Nearly 1 billion people lack access to clean drinking water
- Traditional water sources cannot meet growing demand
The Solution:
- Oceans cover 71% of Earth's surface, representing an abundant resource
- SWRO technology efficiently converts seawater to potable water
- Proven technology with thousands of successful installations worldwide
How SWRO Desalination Works
4-Stage Purification Process:
1. Seawater Intake & Pretreatment
- Raw seawater extraction and screening
- Turbidity reduction and suspended solids removal
- Biofouling prevention through chemical treatment
- SDI reduction to protect downstream membranes
2. High-Pressure Pumping
- Specialized corrosion-resistant pumps
- Operating pressures: 55-85 bar (800-1200 psi)
- Energy recovery system integration
- Stable pressure maintenance
3. RO Membrane Separation
- High-rejection seawater membranes
- 99.4%+ salt removal efficiency
- TDS reduction: 36,000 mg/L → 200 mg/L
- Continuous permeate production
4. Post-Treatment & Mineralization
- pH adjustment and corrosion control
- Remineralization for taste and health benefits
- Disinfection and stabilization
- Quality monitoring and distribution
