Seawater desalination
Water Island platform for seawater and brackish water
Product overview
Unconventional sources, the same factory-built platform
This offering applies the Water Island platform to unconventional water sources — especially seawater and brackish water — to supply high-quality water for industrial enterprises, industrial parks, and towns.
Equipment is manufactured, commissioned and trial-run in the factory, then quickly assembled on site.
- Capacity range 2,000–50,000 t/day; 5,000 m³/d type combinable into 10,000 / 15,000 / 20,000 m³/d
- Process: UF + RO, spiral-wound membrane, 1 stage / 3 sections
- 40 ft standard modules; AI unattended operation
Application architecture
Seawater and brackish water across three scenarios
The same Water Island architecture, with seawater and brackish water as the unconventional source path for water supply, alongside the resource-recovery path.
Industrial
Industrial park
Municipal / towns
Conventional water: reservoir, groundwater, river, lake.
Unconventional water: sewage, mine water, brackish water, seawater.
Typical performance (5,000 m³/d base type)
Published typical values; actual performance depends on influent quality.
| Parameter | Typical value |
|---|---|
| Product flow (base type) | 5,000 m³/d |
| Salt rejection | ≥97% |
| Recovery | ~75% |
| Product CODMn | ≤5 mg/L |
| Product TDS (1)(2) | ≤100 mg/L |
| Operating pressure | ≤16 bar |
(1) The TDS figure is stated in the product materials as better than China’s Standards for Drinking Water Quality GB5749-2006 and the WHO drinking-water guidelines.
(2) Better than GB/T 1576-2018 (industrial boiler water, softened water) and GB/T 19923-2005 (urban wastewater reuse — industrial water: boiler makeup and process/product water).
When the influent is WWTP effluent, it should meet Grade 1A or better of the integrated wastewater discharge standard; pretreatment modules are matched to actual project water quality.
These are typical water-quality indicators; actual results depend on incoming water quality.
