World Water Day 2025 – How UV & Ozone Water Treatment assists Sustainability
21 March 2025World Water Day, celebrated every year on March 22, reminds us how important clean and safe water is and why we must take care of it. This year’s theme, “Glacier Preservation,” highlights how glaciers play a vital role in our water supply but are shrinking due to climate change.
As we reflect on water sustainability, it’s crucial to recognize the advancements in water treatment technologies, particularly ultraviolet (UV) and ozone treatments, which contribute significantly to preserving water quality and ensuring the safety of water supplies. These technologies offer efficient and eco-friendly solutions by effectively eliminating pathogens and contaminants without the use of harmful chemicals.
The Importance of UV and Ozone in Water Treatment
Traditional water treatment methods often rely on chemical disinfectants like chlorine, which, while effective, can produce harmful byproducts. In contrast, UV and ozone treatments offer alternative approaches:
UV Treatment
- Utilizes ultraviolet light to inactivate microorganisms by damaging their DNA, effectively neutralizing pathogens without introducing chemicals into the water.
Ozone Treatment
- Employs ozone gas as a powerful oxidizing agent to break down contaminants, including organic micropollutants and pathogens, enhancing water quality.
Environmental and Health Benefits
The adoption of UV and ozone treatments presents several advantages:
- Energy Efficiency: Continuous advancements in these technologies have led to enhanced energy efficiency, supporting sustainability objectives by reducing energy consumption while ensuring high performance in water treatment.
- Reduction of Harmful Byproducts: Unlike chlorination, these methods do not produce significant disinfection byproducts, thereby reducing potential health risks.
- Effective Contaminant Removal: Ozone-based advanced oxidation processes have demonstrated efficacy in degrading persistent organic pollutants, addressing contaminants that traditional methods may not effectively remove.
Case Studies Highlighting Effectiveness
We are proud to help communities and businesses solve water challenges with our advanced UV and ozone technologies.
Some of the cases where we sustainably solved water treatment challenges include:
Carlsberg Brewery in Denmark
Implemented an advanced water treatment plant that allows for 90% reuse of process water, reducing the beer-to-water ratio from 2.9 hl/hl to 1.4 hl/hl. This initiative positions Carlsberg ahead of its 2030 sustainability targets.
RESC – Rescue & Safety Center
Developed a full-scale treatment plant to remove PFAS from contaminated water streams, achieving reductions from approximately 25,000 ng/l to below detection limits.
Drinking Water Facility
The UV system ensured safe, chemical-free drinking water while doubling water capacity, reducing environmental impact, and supporting sustainable water supply for a growing population.
Our Commitment to a Clean Water Future
