If you’re a homeowner, there are a number of things you should always consider. Maintenance, minor repairs… One thing most people take for granted is the quality and cleanliness of their water. But without UV disinfection for homes and cottages, it’s difficult to guarantee potability, especially when the source is not the mains water supply.

These days, there are many ways to ensure that the water you drink from your tap is clean, germ-free and safe to drink. You could certainly get a filter for your tap, or filter your drinking water with a special jug, but even these household items cannot guarantee that your water will be completely free from harmful germs. The price may be higher, but it is possible to guarantee clean water in your home.

By using a UV water steriliser, you can effectively purify all the water that enters your home. These devices cover a wide range. They can be a little tricky to install and require some modifications to your home’s existing water system, but they can make all the difference if clean water is your goal.

You’ll need to pre-treat your water so that it’s already clean enough, free from sediment and taint, for the ultraviolet systems in these devices to work properly. They also require annual or bi-annual maintenance. However, these are small prices to pay for peace of mind when it comes to your water.

Water purification system for the home

Ultraviolet treatment is the safest method for disinfecting water intended for human consumption. The reactors selected by 1H2O3 are used for :

make untreated water from local resources (wells, boreholes, water intakes, etc.) drinkable.
ensuring the safe use of mains water, particularly after dechlorination with activated carbon
make recycled rainwater safe to use, for sanitary purposes only

1H2O3 UV sterilisers guarantee compliance with bacteriological water quality limits (in accordance with the FR decree of 25/12/2003) and comply with the Ministry of Health Directive on UV treatment. Prior filtration may be necessary depending on the quality of your source. As each country has different rules, it is advisable to check and comply with the standards in force in your country.

Advantages of UV disinfection for human consumption

1H2O3 UV-C treatment for disinfecting water and making it fit for drinking has a number of advantages. In addition to technology that guarantees exemplary water quality for drinking water, the UV disinfection system is highly reliable and easy to use.

Excellent UV disinfection performance thanks to advanced optimisation of ultraviolet emissions and hydraulic flow,
Compact water treatment units for easy installation,
Use of specific UV-C lamps for water sterilisation,
Optional UV sensor or monitor with LED alarm and dry contacts for reporting,
Very long life of UV lamps for water treatment
Easy-to-use treatment. Does not alter the physico-chemical characteristics of the water: no change in taste, odour, etc.
No disinfection by-products harmful to human health.
No risk of under- or overdosing
No need to monitor or handle chemical products
Can be combined with other treatment processes (filtration, softening, etc.)

Design advice: UV disinfection for human consumption

Go to the UV sizing page:

Select ” Drinking water / Sterilization “.
Select the water source to be potabilized, e.g. “Potabilization of well water”.
Enter the flow rate to be treated (for example 2 m3/h, which is more than enough for a house of 4 people).
Adjust the cost of electricity in your country (for example 0.09€ for France; 0.23€ for Germany)
Enter 40 mJ / cm² (the basic value is 30 mJ/cm²)
Specify the water temperature (normally, between 5 and 40°C is sufficient, unless you are pumping your water from a well in Canada).
Please enter your email address, we will send you the design right away

In any case, to ensure optimal disinfection and to determine whether prefilters are necessary, it is recommended that a source water analysis be performed with these parameters:

Iron
Hardness
Turbidity
Manganese
Suspended solids (TSS)
UV Transmittance

FAQ

La désinfection UV est-elle efficace contre les virus comme le norovirus ou le rotavirus ?

Oui, la technologie UV-C est efficace contre de nombreux virus, y compris le norovirus, le rotavirus et l’hépatite A. Ces rayons UV désactivent les virus en perturbant leur matériel génétique, ce qui les empêche de se reproduire ou de provoquer une infection. Toutefois, pour une efficacité maximale, l’eau doit être claire et sans particules, car les matières en suspension peuvent limiter la pénétration du rayonnement UV.

Peut-on utiliser un système UV pour l’eau de pluie destinée à la consommation ?

Oui, un système UV peut parfaitement être utilisé pour désinfecter de l’eau de pluie, à condition qu’elle soit d’abord correctement filtrée. L’eau de pluie peut contenir des particules fines, des bactéries ou des virus. Un prétraitement (filtres à sédiments) est donc indispensable pour garantir une transmission suffisante des rayons UV et assurer une désinfection complète.

Quelle est la durée de vie d’une lampe UV et quand faut-il la remplacer ?

La plupart des lampes UV ont une durée de vie comprise entre 8 000 et 10 000 heures, ce qui équivaut à environ un an d’utilisation continue. Même si la lampe fonctionne encore visuellement après ce délai, son efficacité germicide diminue progressivement. Il est donc fortement recommandé de la remplacer tous les 12 mois pour garantir un traitement optimal de l’eau.

Un système UV nécessite-t-il une maintenance régulière ?

Oui, un entretien minimal mais régulier est nécessaire. En plus du remplacement annuel de la lampe, le manchon de quartz qui protège la lampe doit être nettoyé pour éviter toute accumulation de dépôts (calcaire, fer, biofilm) qui réduirait l’efficacité du rayonnement. Un contrôle visuel mensuel et un nettoyage semestriel suffisent généralement pour un usage domestique.

Le traitement UV altère-t-il le goût ou l’odeur de l’eau ?

Non, l’un des grands avantages du traitement UV est qu’il n’altère en rien les qualités organoleptiques de l’eau. Il ne modifie ni le goût, ni l’odeur, ni la composition chimique de l’eau, car il ne fait appel à aucun produit. C’est une méthode de désinfection totalement naturelle et respectueuse de l’environnement, idéale pour ceux qui souhaitent éviter l’utilisation de chlore ou d’autres additifs.
