Reverse Osmosis (RO) & Desalination Systems
Whether you're treating bore water at a remote mine site, desalinating seawater for a coastal facility, or supplying potable water to a regional community - Centurion Water designs, builds, installs, operates and services the complete treatment plant. Not just the equipment. The whole solution.

At a Glance
- BWRO (brackish reverse osmosis) and SWRO (seawater reverse osmosis) systems, 50–500 m³/day standard capacity
- Treat bore water, brackish water and seawater to potable or process water quality
- Typical recovery: 60–85% BWRO / 40–60% SWRO
- Skid-mounted, modular or containerised - built for remote and fast-deployment projects
- End-to-end delivery: design, build, commission, operate and service
- Available to purchase, rent, or rent-to-own
Which System Do You Need? BWRO vs SWRO
The right system comes down to how salty your source water is.
| Feed Water | Typical TDS | System | Recovery |
| Bore water/ brackish | Below 5,000mg/L | BWRO | 60-85% |
| Transitional salinity | 5,000-10,000mg/L | Assessment needed | Varies |
| Seawater/ high salinity bore | 10,000-45,000mg/L | SWRO | 40-60% |
A few other factors shape the final design: feed water TSS should generally be below 30 mg/L before entering the RO stage; operating temperature range is 15°C–40°C; and brine management needs to be factored into site layout from the start. SWRO also draws significantly more power than BWRO, which matters for remote or off-grid sites.
If your water has elevated iron, manganese, turbidity or oils, pre-treatment will be required before the RO membranes - Centurion assesses and integrates this as part of the full plant design rather than leaving it for someone else to solve.
What's Included
Centurion Water supplies complete, ready-to-deploy systems. Depending on your project, a system typically includes:
- Feed pumps, media filtration and cartridge filtration
- Antiscalant dosing and chemical cleaning (CIP)
- RO pressure vessels and high-pressure pumps
- MCC panel, PLC controls and HMI touchscreen
- Instrumentation and fail-safe devicesPre-treatment options (integrated where feed water quality requires it): settling tanks, lamella clarifiers or DAF; iron, manganese and heavy metal removal; pH adjustment; de-chlorination; ultrafiltration.
Post-treatment options (matched to your target water quality): remineralisation, pre- and post-chlorination, continuous electrodeionisation (CEDI), brine and reject water management.
Containerised systems can also include air conditioning, lighting, insulation and non-slip flooring.
Power Requirements (Indicative)
| Capacity | BWRO Power | SWRO Power |
| 50 m³/day | ~5 kW | ~20 kW |
| 500 m³/day | ~30 kW | ~80 kW |
SWRO runs at higher pressure than BWRO and uses more power. Energy Recovery Devices (ERDs) are available on suitable SWRO applications. Power supply is typically 3-phase, 50 Hz, 380–415V.

End-to-End Project Support
Centurion can manage the full lifecycle of your RO and desalination system, from initial water testing through to long-term operation and maintenance.
We can support:
- Design & Engineering - feed water analysis, system selection, full plant design
- Build & Install - fabrication, delivery, site installation and commissioning
- Operate & Maintain - operator training, on-site operators, scheduled servicing, emergency support, spare parts and chemicals
- Upgrade - retrofit or expand existing RO and desalination systems, including third-party equipment
Commercial options include purchase, rental, rent-to-own and integration with existing assets.
Frequently Asked Questions (FAQ)
Q: What's the difference between reverse osmosis and desalination?
A: Desalination is the goal - removing salt to produce usable water. Reverse osmosis is the technology most commonly used to achieve it. BWRO handles lower-salinity sources; SWRO handles seawater and high-salinity bore water.
Q: How do I know what information you need to size a system?
A: Feed water quality is the starting point. Useful information includes: TDS and water analysis results, target treated water quality, daily demand or peak flow, site location, power supply and brine disposal options. No need to have everything upfront — we can help work through it.
Q: Can Centurion service my existing RO system?
A: Yes. We service and maintain Centurion systems as well as third-party RO and desalination equipment — including spare parts, filters, chemicals and fault response.
Q: Can systems be expanded as demand grows?
A: Yes. Our modular design means capacity can be scaled up without replacing the whole plant.
