UV disinfection plays a crucial role in clinical water treatment for demineralized (DI) water, especially in hospitals, laboratories and dialysis centers. Here are the main reasons:
- effective germ reduction - UV-C radiation destroys microorganisms such as bacteria (e.g. Legionella, Pseudomonas), viruses and fungi by damaging their DNA/RNA and preventing them from reproducing.
- chemical-free disinfection - In contrast to chemical disinfection methods (e.g. chlorine, ozone), no harmful by-products or residues are produced, which maintains the water quality.
- prevention of biofilm formation - Clinical water treatment systems are susceptible to biofilms, which protect germs and colonize pipes. UV disinfection interrupts this process.
- ensuring water quality - demineralized water must meet high purity requirements, e.g. for dialysis, laboratories or sterile processing. UV treatment ensures that no microbial impurities contaminate the system.
- compliance with hygiene standards - Hospitals and medical facilities are subject to strict regulations (e.g. DIN EN 285, ISO 15883). UV disinfection helps to meet these standards.
- cost efficiency & environmental friendliness - UV systems have low operating costs, require no chemicals and cause no disposal problems due to disinfectant residues.
Overall, UV disinfection is an essential part of hospital water treatment to ensure patient safety and the highest standards of hygiene.
Water sterilisation by UV irradiation The development of water sterilisation using UV radiation has made considerable progress in recent years due to its simplicity and efficiency. The UV-C rays generated, which are significantly more intense than sunlight, are therefore used to disinfect water in order to counteract water contamination. They make it possible to remove legionella, microbes, bacteria, viruses and protozoa while respecting the environment. The irradiation process is therefore an ideal solution for killing microorganisms in water and helps to make it drinkable from a bacteriological point of view. However, it is important to note that water is only considered drinking water once the chemical parameters have been checked and deemed satisfactory. Applications - Origin of the water Rainwater: UV treatment extends the range of applications and offers increased safety during use Well water: Avoidance of possible contamination by pathogens Spring water, surface water: Guarantees constant water quality that is flawless from a bacteriological point of view. Storage water in containers (caravan, boat...): Use of stored water for sanitary purposes. Areas of application General nutrition, bath and shower Cooking Large-volume refrigerators Cold water fountains Aquarium Cleaning food Advantages Quick and easy installation Completely physical sterilisation through UV radiation Natural water treatment without additives and without the risk of chemical overdose No unpleasant taste or odour Effective methods for combating microorganisms that cause disease in humans No toxic by-products Low maintenance Notice: The product is not approved for use in drinking water systems and does not hold the corresponding DVGW drinking water certification. Therefore, it must not be used in applications where drinking water approval is required. Frequently Asked Questions Why do I need UV water disinfection in the first place? It helps to reduce bacteria and germs in the water – without any chemicals or additives. What is the difference between the UV2100 and the UV4100? The UV4100 is designed for larger volumes of water, whilst the UV2100 is more suited to smaller systems or households. Can I simply install the system into my existing water pipe? In many cases, yes. The units fit standard 3/4″ and 1″ connections. Does UV treatment change the taste of my water? No. UV disinfection works without chemicals and does not alter the taste of the water. How often do I need to replace the UV lamp? Usually once a year to ensure the system works reliably. Do I also need a water filter upstream of the UV system? This is often advisable to prevent dirt particles from impairing the effectiveness of the UV disinfection. Is the system also suitable for well water? Yes, it is frequently used to hygienically treat well water.
