Water Island
Factory-built integrated water-treatment equipment
Product overview
Factory manufactured, commissioned and trial-run — then quickly assembled on site
Water Island is manufactured, commissioned and trial-run in the factory, then quickly assembled on site to supply high-quality water for industrial enterprises, industrial parks, and towns.
It addresses water shortage, limited environmental capacity, water safety, and high cost.
- Capacity range 2,000–50,000 t/day
- 40 ft standard modules; other scales can be extended modularly
- Water sources: surface water, groundwater, WWTP effluent, etc.; unconventional sources include seawater and brackish water

Typical performance (5,000 m³/d base type)
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.
The product series is listed in the National Catalogue of Encouraged Industrial Water-Saving Processes, Technologies and Equipment (2025), compiled by MIIT and the Ministry of Water Resources (per the product materials).
