Industrial Seawater Ro Treatment Systems Reverse Osmosis Desalination Solutions - China

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.
