Reverse Osmosis
At Barr + Wray, we specialise in the design, supply, and installation of high-performance Reverse Osmosis (RO) systems for a wide range of industrial and commercial applications.
Engineered Reverse Osmosis Solutions for Critical Applications
With decades of experience in water treatment engineering, we deliver fully integrated RO solutions.
Tailored to meet the specific needs of sectors such as pharmaceuticals, food and beverage, power generation, electronics, and wastewater reuse.
Reverse osmosis is a proven and efficient method for producing high-purity water by removing up to 99% of dissolved salts, minerals, and impurities. Water is pressurised and pushed through semi-permeable membranes that reject contaminants while allowing clean water molecules to pass. The result is consistently clean, demineralised water suitable for critical processes.
Our RO systems typically include:
- Pre-treatment units (to remove sediment, chlorine, and other harmful substances)
- High-pressure pumps for optimal membrane performance
- Membrane modules engineered for long life and high rejection rates
- Post-treatment options, such as UV disinfection, pH correction, or mixed-bed polishing
Barr + Wray’s RO solutions are designed for efficiency, reliability, and ease of maintenance. We also offer automated control systems and remote monitoring options to optimise performance and reduce operator workload.
In addition to supplying new RO systems, we provide ongoing maintenance, membrane cleaning, replacement, and system upgrades, ensuring long-term system health and performance.
Whether for demineralisation, desalination, or wastewater recovery, Barr + Wray delivers robust RO solutions that meet today’s stringent water quality demands across a wide range of industries.
