Pretreatment filtration | Main filter: 5 μm absolute filtration; pre-filter: 1 μm nominal filtration |
Feed-water conditions | The page describes seawater feed. It notes that direct feed or temporary feed-tank storage depends on intake distance and seawater turbidity |
Temperature, pH, and other feed-water limits | Not specified on the supplied page content |
Cleaning conditions | CIP equipment is listed, but cleaning pressure, temperature, pH, and procedure are not specified |
4. Key Features & Benefits
Integrated containerized configuration: Pretreatment, RO, chemical cleaning, and dosing equipment are housed in a standardized container.
Model-specific membrane capacity: The series uses 5–12 Type 8040 membrane elements, depending on model, helping buyers compare configurations.
Variable-frequency high-pressure pump: The listed high-pressure pump includes a VFD.
Seawater pretreatment stages: The listed 5 μm absolute main filter and 1 μm nominal pre-filter provide staged filtration before RO.
Container options: The page lists a commonly used 20 ft container and an optional 40 ft container.

5. Key Applications
Freshwater supply for island communities
Water supply for coastal hotels and resorts
Freshwater production for coastal or remote construction sites
Emergency and temporary water supply
Treatment of high-salinity groundwater, subject to feed-water analysis and system configuration
