Demineralised Water
Demineralised (demin) water treatment is the process of removing dissolved mineral salts such as calcium, magnesium, sodium, chlorides, sulphates, and bicarbonates from water.
Demineralised Water Systems for Precision and Purity
This high-purity water is critical in industries where even trace levels of minerals can interfere with processes, including pharmaceuticals, power generation, electronics manufacturing, and food and beverage production.
At Barr + Wray, we have extensive experience in delivering tailored demineralised water systems across a range of sectors, with particular expertise in the whisky and electronics industries.
In whisky production, water is used not only as a key ingredient but also throughout the mashing, fermentation, dilution, and cleaning stages. The mineral content of untreated water can significantly affect flavour, clarity, and product consistency. We provide demin systems that help distillers achieve the water quality needed for a consistently high-quality product.
In the electronics industry, ultra-pure water is essential to prevent contamination and defects. Barr + Wray supplies advanced multi-stage treatment systems that often combine ion exchange, reverse osmosis, electro-deionisation, and degassing to meet the ultra-high purity standards required.
We also support applications such as boiler feed water treatment, where the removal of minerals is essential to prevent scaling, corrosion, and reduced efficiency.
Our core demineralisation technologies include:
- Ion Exchange – Resin beds replace unwanted ions with hydrogen and hydroxide, producing pure water.
- Reverse Osmosis (RO) – Removes up to 99% of dissolved salts and impurities using semi-permeable membranes.
- Mixed-Bed Polishing – Used post-RO to achieve ultra-pure water, especially for electronics and high-spec applications.
Barr + Wray’s systems are engineered for performance, long-term reliability, and compliance with strict industry standards.
