Containerized RO seawater desalination plant system
Need reliable fresh water anywhere? Our containerized RO solutions turn seawater into safe, usable water—fast. Fully assembled inside 20ft or 40ft containers, these mobile units are ready to go where you need them most. Whether it’s a coastal village, a desert worksite, or an offshore rig, just plug in and start producing clean water for people, plants, or processes.
Containerized RO systems are compact, fully integrated desalination solutions designed for treating seawater, brackish water, or borehole sources. These mobile units are ideal for producing clean water for drinking, irrigation, or industrial use—especially in remote or space-constrained environments.
Source Water: Direct seawater, drilled saline water, or borehole sources
Application: Drinking water, agricultural irrigation, industrial processing

Why Choose a Containerized RO Desalination System?
A containerized RO (Reverse Osmosis) system offers a compact, mobile, and efficient solution for seawater desalination. Compared to traditional built-in plant rooms, containerized units provide multiple operational and logistical advantages:
-
Ready-to-use design – fully pre-assembled and tested
-
Rapid deployment – minimal setup time on-site
-
Reduced civil works – only requires a simple container foundation
-
Compact footprint – ideal for space-limited environments
-
Flexible mobility – perfect for remote areas, construction sites, or temporary facilities
-
Complete integration – includes piping, wiring, and optional climate control
-
Turnkey delivery – just connect inlet and outlet, and it’s ready
