Overview: High-Efficiency Seawater Reverse Osmosis (SWRO)
As global demand for fresh water intensifies, industrial and municipal sectors require robust, scalable solutions to treat seawater. The Veolia SeaPRO Series stands as a premier line of skid-mounted Seawater Reverse Osmosis (SWRO) systems, engineered to convert seawater into high-quality permeate for potable use, industrial processes, and utility applications.
At Purecowater, we supply the complete range of Veolia desalination technology. The SeaPRO series is designed to tackle high-salinity challenges with integrated energy recovery devices, ensuring operation is both reliable and cost-effective.
Product Configurations: SeaPRO vs. SeaPRO-E
The SeaPRO platform is available in two distinct configurations to meet varying capital expenditure (CAPEX) and operating expenditure (OPEX) requirements.
1. The Premium SeaPRO System
The standard SeaPRO line is the flagship solution tailored for maximum energy efficiency and flexibility. It is capable of handling flow rates ranging from 100 to nearly 2,750 m³/day (20 to 500 gpm).
- Energy Recovery: Utilizes turbochargers for smaller units (SeaPRO-8 through SeaPRO-28) and highly efficient pressure exchangers for larger systems (SeaPRO-42 through SeaPRO-210).
- Feed Water Flexibility: Options for 35% recovery (designed for 45,000 ppm TDS) or 45% recovery (designed for 35,000 ppm TDS).
- Control: Equipped with Variable Frequency Drives (VFD) on high-pressure pumps for precise flow control.
2. The SeaPRO-E (Economy) System
The SeaPRO-E series is engineered for projects prioritizing lower capital investment without sacrificing core reliability. It covers flow rates from 500 to 2,500 m³/day (92 to 460 gpm).
- Optimized Design: Features a reduced feature set to lower upfront costs.
- Energy Recovery: Utilizes turbochargers across the entire range.
- Performance: Designed for 45% recovery on feed water up to 45,000 ppm TDS.

Key Features & Benefits
- Skid-Mounted Design: Pre-configured and assembled off-site to reduce installation time and footprint requirements.
- Global Compatibility: Power options available for both 50 Hz and 60 Hz operations, making these units suitable for international maritime and land-based facilities.
- Advanced Hydraulics: The inclusion of VFDs protects high-pressure pumps and allows for “soft starts,” extending equipment lifespan and reducing mechanical stress.
- Durability: Constructed to withstand the corrosive nature of heavy seawater environments, ensuring long-term asset protection.
Typical Applications
The Veolia SeaPRO series is ideal for a wide range of applications where freshwater scarcity is a pressing issue:
- Municipal Drinking Water: Supplemental water supply for coastal cities and island communities.
- Resorts and Hospitality: Ensuring consistent potable water for hotels in remote locations.
- Industrial Process Water: Providing treated water for cooling towers, boilers, and manufacturing in coastal industrial zones.
- Offshore & Key Marine: Reliable freshwater production for platforms and vessels.
Contact Purecowater for System Sizing
Selecting the right desalination system requires analyzing your specific feed water chemistry (TDS, temperature, fouling indices) and your required permeate quality. As a distributor for Veolia Water Technologies & Solutions, Purecowater can assist in specifying the correct SeaPRO model for your facility.
