Discover the Aquadem demineralized water range, tailored for industrial applications, healthcare and laboratories.
Overview
Aquadem operates using demineralizer cylinders filled with regenerable cationic and anionic mixed-bed resins, based on simple hydraulic and chemical principles. The system’s availability is maximized thanks to the reliability of its components.
Aquadem’s procedures ensure final water quality above 14.5 megaohms-cm (MΩ.cm) for each regenerated resin batch. This is tested on calibration benches and quality curves provided upon request.
Although frequently used with mains water, Aquadem technology can also be deployed as a polishing step for pre-treated water (including reverse osmosis and electrodeionization), allowing for unmatched water quality for a wide range of industrial and scientific applications.
- The spent demineralizers are collected by local Veolia Water Technologies branches.
- The saturated resins are regenerated and tested at our specialized production centers, ensuring full traceability and performance.
- The regenerated demineralizers are then delivered through a standard exchange system (delivering the regenerated cylinder and retrieving the spent one), ensuring continuous demineralized water production.

FAQ about Aquadem
What is demineralized water?
Demineralized water is water from which dissolved minerals (such as calcium, magnesium, sodium, etc.) have been removed. It is used in applications requiring high-purity water to prevent interference with industrial and analytical processes.
How does mixed-bed demineralization work?
Ion exchange demineralization works by using resins that replace dissolved ions in water with hydrogen (H+) or hydroxide (OH-) ions, producing pure water with low electrical conductivity. In mixed-bed systems, both cationic and anionic resins are combined for more efficient ion removal and optimal pH control. However, during regeneration, the resins need to be separated.
What applications are suitable for demineralized water?
Demineralized water is used in various sectors:
- Laboratories: Demineralized water
- Cosmetics: Process water, environmental chambers, glass rinsing, photovoltaics
- Chemical manufacturing: Water rinsing and polishing
- Microelectronics: Water polishing
- Pharmaceuticals and biotechnology: Process and purified water
Do ion exchange resins need to be replaced regularly?
Ion exchange resins do not need to be replaced after each use but must be regenerated when their exchange capacity decreases. This is done using specific regenerating solutions (hydrochloric or sulfuric acid for cationic resins, caustic soda for anionic resins). However, if the resins are damaged or exhausted, they should be replaced to maintain optimal performance.
What are the essential maintenance tasks for water demineralizers?
To ensure optimal performance and prolong the lifespan of water demineralizers essential maintenance includes:
- Monitoring operational parameters
- Regenerating and replacing resins
- Cleaning and disinfecting
- Inspecting pre-filters
- Checking pumps and valves
- Monitoring consumables
- Recording data and interventions
- Verifying control systems
Case Studies
An industry leader in the waste treatment was struggling to achieve and maintain precise water quality standards for their demineralization systems at three of their waste recycling and recovery facilities.
The sites required exceptional water purity, with conductivity not exceeding 0.2 µS/cm and strict limitations on silica, iron, copper and alkali metals.
Our team implemented dual Aquadem mixed-bed units at each location with advanced monitoring equipment, featuring resistivity and silica meters for precise quality control.
Thanks to Aquadem we eliminated the need for storage or discharge facilities while maintaining consistent water quality. It also proved particularly effective for their steam boiler turbine applications and optimized the water treatment processes at the waste-to-energy facilities.
