To understand in a few lines how a micro-filtered water fountain works, visit the dedicated page: how a water filter fountain works.
Microfiltration is a membrane filtration process that removes particles from water that are around one micron in size (100 times finer than the thickness of a hair). At Castalie, the membrane mesh size is 0.5 microns, one of the finest microfiltration mesh sizes possible.
In addition to this membrane, Castalie activated carbon into its filters. The role of activated carbon is to remove chlorine from the mains water supply to stabilize the bacteriology. As a result, Castalie water Castalie completely neutral in taste. This carbon also plays an important role in adsorbing heavy metal residues, pesticides, pesticide metabolites, and PFAS, the infamous forever chemicals. Castalie microfiltration Castalie remove the minerals naturally present in water, in order to guarantee optimal sparkle.Castalie water fountains deliver still water (room temperature, chilled, or hot) as well as sparkling water, tailored to your preferences and the model selected.
We offer a wide range of water coolers to suit all your needs, based on several criteria such as: the type of water required (still, sparkling, hot, cold), the space available, the number of users, etc.
As each project is unique, we invite you to contact us or discover here which water fountain could be best suited to your needs.
With the Anti-Waste Law for a Circular Economy (AGEC), establishments open to the public (ERP) and premises for professional use (businesses, warehouses, factories, etc.) can no longer distribute free plastic bottles to their occupants or users. Practical, economical, and environmentally friendly, water coolers are the best solution to meet this requirement.
Public establishments that can accommodate between 301 and 600 people must also be equipped with at least one drinking water fountain. For more than 600 people, you will need to install one new fountain for every additional 300 people.

Installing a water fountain in your premises has many advantages.

You can also offer them still or sparkling water, ideal for quenching their thirst throughout the day. Microfiltration guarantees high-quality water with a great taste, free from impurities, numerous pollutants, and the taste of chlorine.
Unlike a beverage dispenser or a fountain supplied by bottles, a water fountain does not require restocking or storage space. Handling a 13-liter or 20-liter bottle can also be tiring and lead to accidents. On the other hand, servicing three times a year ensures that our Castalie water coolers continue to function properly over the long term. This is carried out by our technical department, giving you guaranteed peace of mind.
The total absence of plastic significantly reduces your environmental impact and aligns with your CSR commitments.
All businesses, government agencies, and local authorities can install a water fountain on their premises, regardless of their sector of activity or size. Small businesses can opt for a single unit, while larger organizations can deploy multiple units.

Our various models, whether indoor or outdoor, can be installed in a variety of locations such as offices, shopping centers, amusement parks, train stations, schools, tourist areas, and green spaces.
The filtration system is based on a membrane with a mesh size of only 0.5 microns, which is 200 times finer than the thickness of a single hair. Many unwanted particles are stopped by this mesh, and our filters also incorporate activated carbon, which adsorbs the chlorine added to stabilize drinking water. Activated carbon also retains some traces of pesticides, pesticide metabolites, and persistent pollutants (PFAS). Microfiltration allows minerals naturally present in the water to pass through.
