High-Capacity RO Seawater Desalination Plant
Our industrial RO seawater desalination plants provide a capacity range of 2m³/hour to 2500m³/day. For lower capacity needs, check out our commercial RO desalination machines.
How Does an Industrial RO Seawater Desalination Plant Work?
All RO desalination systems begin with a booster pump, which feeds raw water into pretreatment tanks. Depending on capacity, the size and number of pretreatment tanks can vary. Since seawater has a high TDS (Total Dissolved Solids) and is highly corrosive, we use FRP (Fiber Reinforced Plastic) or carbon steel materials for durability.
Key Pretreatment Components:
- Sand Media Filter Tank – Removes suspended solids, sediment, and turbidity.
- Activated Carbon Filter Tank – Eliminates chlorine, organic contaminants, odors, and unwanted colors.
- Softener Tank with Ion Exchange Resin – Prevents scaling by reducing hardness.
Reverse Osmosis Seawater Purification System
The RO purification system removes: ✅ Dissolved salts
✅ Heavy metals
✅ Bacteria & viruses
✅ Organic & inorganic solids
✅ Proteins, dyes, and unwanted particles
Step-by-Step Water Filtration Process
-
Pretreatment Stage: Filters out large suspended solids and organic contaminants.
-
Cartridge Filter Housing (Security Filter): Uses 1µm or 5µm PP filters to remove finer particles before entering high-pressure pumps.
-
High-Pressure Pump & Membrane Filtration:
- We offer Grundfos, Danfoss, CNP, or Chunke high-pressure pump options.
- RO membranes from DOW Filmtec, Toray, Vontron, Hydranautics, and LG ensure 99% salt rejection.
- Membranes available in 4040 and 8040 sizes based on system capacity.
-
Post-Treatment & Chemical Dosing:
- Anti-scalant & anti-fouling agents prevent membrane clogging.
- pH adjustment, sterilization, and disinfection chemicals for improved water quality.
- Optional CIP (Clean-In-Place) System extends membrane lifespan.

What is a Reverse Osmosis (RO) Desalination System?
A reverse osmosis (RO) desalination system is designed to remove salt from seawater, making it usable for industrial, municipal, and drinking water applications. Our industrial seawater desalination plants use RO membrane technology, which ensures 99% salt removal, delivering fresh and clean water efficiently.
Why Choose Reverse Osmosis for Seawater Purification?
- ✅ High Salt Removal Efficiency – Over 99% salt rejection.
- ✅ No Chemical Phase Change – Operates at normal temperature, reducing energy costs.
- ✅ Compact Design – Requires minimal space while providing high-capacity filtration.
- ✅ Automation & Monitoring – Programmable PLC control ensures ease of operation.
- ✅ Cost-Effective & Energy-Efficient – Lower operating costs compared to thermal desalination.

Industrial RO Desalination Machine – Cost Considerations
The cost of an industrial seawater desalination system is higher than that of a regular freshwater RO system. This is because:
- High-pressure pumps are required to handle seawater’s high salinity.
- Corrosion-resistant materials (FRP, stainless steel) increase longevity.
- Advanced filtration membranes are used for high-recovery desalination.
Why Choose Our Industrial Seawater RO Desalination Systems?
✅ Customizable to Your Water Analysis – Tailored design based on your specific water quality.
✅ Global Quality Standards – We use ISO, FDA, and NSF-certified components.
✅ Low Maintenance & Long Lifespan – Equipped with CIP (Clean-In-Place) system to extend membrane life.
✅ Competitive Pricing & Cost-Efficiency – Best balance of affordability, performance, and durability.
