Containerized RO Systems
Last updated: July 15, 2026
A containerized RO system is a complete reverse osmosis water treatment plant built inside a shipping container or purpose-built enclosure, ready to transport and connect on site. It houses pretreatment, membranes, pumps, and controls in one weatherproof unit, so a site gets treated water without building permanent infrastructure. AMPAC USA's mobile/containerized line spans from 50 GPD man-portable backpack units up to 100,000 GPD containerized plants housed in standard 20-foot ISO containers (AMPAC USA, 2026).
Remote sites, disaster zones, and temporary operations rarely have time to build a water treatment plant from scratch. A containerized unit ships pre-assembled, gets set on a pad or trailer, and can be producing treated water within days of arrival rather than months.

What's Inside a Containerized RO Unit?
A containerized RO unit packs pretreatment, RO membranes, a power system, and protective housing into a single enclosed footprint that's ready to run at delivery. Everything is pre-plumbed and pre-wired at the factory, which cuts on-site installation down to hookup and startup.
Pretreatment Stage
Before water reaches the membranes, it typically passes through sediment filtration and often carbon or antiscalant dosing to protect the membranes from fouling. The exact pretreatment train depends on the source water - AMPAC's containerized line is configured for surface water (rivers, lakes, ponds with high turbidity), brackish groundwater (1,000-10,000 ppm TDS), and open-ocean seawater (up to 45,000 ppm TDS, depending on configuration) (AMPAC USA, 2026).
Membrane and Pump Skid
The RO membranes and high-pressure pumps sit on an internal skid, isolated from the elements by the container shell. This skid is where raw or pretreated water is forced through semi-permeable membranes to strip dissolved solids and produce permeate. AMPAC doesn't publish exact membrane count/array configuration per capacity tier - that detail scales with the specific GPD size ordered and would need product-team confirmation for a spec table.
Power and Controls
Containerized systems can typically run on grid power, generator power, or a hybrid setup, with a control panel monitoring pressure, flow, and water quality in real time. AMPAC's line specifically supports four configurations: solar panels with MPPT controller and battery bank, diesel or gasoline generator, shore power (120/240V single-phase or 208/480V three-phase), or a hybrid solar-plus-generator setup (AMPAC USA, 2026). Remote monitoring capability matters most for sites without a full-time operator on hand.
Housing and Transport
The container itself is the deployment advantage: a standard 20-foot ISO container footprint means the whole plant moves by truck, ship, or cargo plane, and drops into place without a construction crew (AMPAC USA, 2026). Insulation and climate control inside the housing protect equipment in extreme hot or cold environments.
Where Are Containerized RO Systems Deployed?
Containerized RO systems get deployed anywhere a permanent treatment plant isn't practical but treated water is still urgently needed - disaster relief zones, military bases, construction sites, and temporary municipal supply gaps. Each use case shares the same requirement: fast setup with no fixed civil works. AMPAC USA specifically cites its systems deployed for disaster relief after Hurricane Maria, the Haiti earthquake, and Typhoon Haiyan, and aboard U.S. Navy vessels (AMPAC USA blog, 2026).
Disaster relief operations need clean water fast after floods, hurricanes, or infrastructure failures, and a containerized plant can be trucked in and running while permanent repairs are still underway.
Military and defense sites often operate in locations with no reliable water infrastructure, where a self-contained plant supports a base without depending on local utilities.
Construction sites with long project timelines sometimes need a temporary water source for dust control, concrete mixing, or worker facilities before permanent utilities are connected.
Temporary municipal supply situations - a water main failure, a contamination event, or a seasonal population surge - can call for a bridge solution while the permanent system is repaired or expanded.
The main tradeoff buyers underweight is logistics, not treatment performance - a containerized unit is only as fast to deploy as the crane, flatbed, and pad prep it needs on arrival, so site access should be scoped before the unit ships.

Frequently Asked Questions
How fast can a containerized RO system be deployed?
Deployment speed depends on transport logistics and site prep, but the core advantage is skipping construction - units are pre-assembled and tested before shipping. AMPAC's own figures: under 30 minutes for man-portable units, 2-4 hours for trailer-mounted systems, and 4-8 hours for full containerized plants once on site (AMPAC USA, 2026).
Can a containerized RO plant run off-grid?
Yes - AMPAC's containerized line supports solar (with MPPT controller and battery bank), diesel or gas generator, or hybrid solar-plus-generator configurations for sites without grid access, alongside standard shore power options.
What feed water sources can a containerized RO unit treat?
AMPAC's containerized units are configured for surface water (rivers, lakes, ponds with high turbidity), brackish groundwater (1,000-10,000 ppm TDS), and open-ocean seawater (up to 45,000 ppm TDS depending on configuration), with pretreatment adjusted to the source.
Does a containerized system need a permanent foundation?
No - most containerized RO plants are designed to sit on a prepared pad, trailer, or level ground without permanent civil works, which is the core reason they suit temporary and emergency deployments.
