SWRO 500

SWRO 500 Seawater Desalination Plant

The SWRO 500 Seawater Desalination Plants by I’mWATER are designed to produce 500 m³/day of potable water, ensuring maximum energy efficiency, reliability, and ease of operation.

Available in both containerized and skid-mounted versions, they can be adapted to any project, from temporary installations to permanent infrastructure.

These plants are part of our EcoMarine range — robust solutions for marine environments and applications requiring a continuous and reliable supply of desalinated water.

The SWRO 500 is positioned as an ideal intermediate solution between small-capacity compact units and large-scale desalination plants, offering an excellent balance between investment cost, energy consumption, and production capacity.

The SWRO 500 is a seawater reverse osmosis plant designed for:

Small coastal municipalities
Medium-sized hotels, resorts, and tourist complexes
Industries with moderate water demand
Ports and yacht clubs
Agricultural facilities near the coast
Campgrounds, residential developments, and remote sites

Its modular design allows the supply of plug & play systems, fully factory-tested and ready for operation in minimal time.

Additionally, its configuration allows future expansion through additional 500 m³/day lines, enabling progressive plant growth.

SWRO 500 Containerized – EcoMarine 500

A fully integrated solution housed within one or more maritime containers, adapted and equipped in our own manufacturing workshops.

Advantages:

Immediate installation: connect and start producing water for human consumption, irrigation, etc.
Reduced civil works
Scalable for future expansions
Simple operation and maintenance
Solar, hybrid, or photovoltaic-assisted energy options available

SWRO 500 Skid-Mounted

Ideal for installations with an available technical room or integration into larger treatment plants.

Features:

Easy access for operation and maintenance
Flexible configuration in modules manufactured and assembled in our facilities
Perfect for existing civil works
Direct integration with auxiliary plant systems

1. Pretreatment

Chemical dosing (biocides, antiscalants)
Media filtration (anthracite, silica sand, or other media)
Final cartridge microfiltration

2. High-Pressure Pumping

Equipment designed to operate between 55 and 70 bar, optimized to ensure efficiency and extend membrane lifespan.

3. SWRO Reverse Osmosis

High-pressure membrane modules
High recovery rate (40–50%)
Design optimized for low energy consumption
Stable production with high permeate quality

4. Energy Recovery

Optional, via pressure exchangers or turbochargers.

The SWRO 500 can achieve optimized energy consumption levels within competitive ranges for seawater applications, particularly when energy recovery systems are integrated.

5. Post-Treatment

Remineralization adjustment
Disinfection control
Conditioning according to final application
CIP & flushing system

6. Auxiliary Systems

PLC with automatic control
Intuitive HMI touch screen
CIP cleaning systems
Optional remote monitoring and control
