Product Description
500L/H RO System Seawater Reverse Osmosis Plant For Domestic Water Supply
The 500 L/H seawater reverse osmosis (SWRO) desalination system converts seawater into clean, safe freshwater for household supply, island communities, coastal homes, and small facilities. Using advanced reverse osmosis technology, this system effectively removes dissolved salts, minerals, bacteria, and other impurities to produce stable, high-quality freshwater for daily use.
This compact desalination unit is ideal for remote coastal areas, islands, marine vessels, resorts, and small communities where access to freshwater resources is limited.
Treatment Process Overview
Seawater Intake → Raw Water Pump → Sand Filter → Activated Carbon Filter → Cartridge Filter → High Pressure Pump → Seawater Reverse Osmosis Membrane → Freshwater Tank → Water Distribution
Detailed Process Components
Seawater Intake System
Draws seawater from the source and delivers it to the pretreatment system.
Multi-Media Sand Filter
Removes suspended solids, sediments, and turbidity to protect downstream equipment.
Activated Carbon Filter
Removes organic compounds, odors, and residual chlorine that may affect membrane performance.
Precision Cartridge Filter (5 μm)
Provides fine filtration to protect the seawater RO membranes from small particles.
High Pressure Pump
Supplies the required pressure for seawater desalination, typically 55-70 bar, enabling efficient salt removal.
Seawater RO Membrane System
The core desalination unit that removes over 99% of dissolved salts, bacteria, and microorganisms, producing freshwater.
Freshwater Storage Tank
Stores the desalinated water for stable household distribution.

Applications for Domestic Water Supply
This system addresses water shortages in coastal areas and islands where freshwater resources are scarce. Ideal for regions such as the Middle East, China's northwestern arid regions, Singapore, and remote islands including the South China Sea islands and the Maldives.
Small-scale desalination equipment producing dozens to hundreds of tons per day is essential for locations that cannot obtain freshwater through water diversion projects. These systems typically feature modular designs to accommodate limited space and can integrate with solar or wind energy sources.
Water Quality Results
After desalination, the produced freshwater typically achieves:
- TDS ≤ 500 mg/L
- Significant reduction of salts and minerals
- Removal of bacteria and microorganisms
- Clear, odor-free freshwater suitable for domestic use
This water quality meets basic household water requirements and can be further treated to achieve drinking water standards if required.
