Water treatment

In a hospital or a health facility, water is omnipresent: care, patient hygiene, food, operation of medical equipment, cleaning of premises … Its quality therefore has a direct impact on health security.

Insufficiently treated water can become a vector of contamination and cause serious nosocomial infections, especially in the most fragile patients (immunocompromised, elderly, patients in resuscitation).

To meet these challenges, several technologies exist. They often complement each other in order to ensure safe water that complies with the highest sanitary standards.

Terminal filtration: secure every sensitive water point

Terminal filtration consists of installing filters directly on the taps, showers or water outlets used in sensitive areas.
These filters, usually in 0.2 μm, effectively retain pathogenic bacteria, including Legionella pneumophila and Pseudomonas aeruginosa, two germs responsible for serious infections.

This solution is particularly indicated:

in the services of resuscitation, oncology or transplants,
to protect immunocompromised patients,
in all areas where exposure to infectious risk is high.

Terminal filters have the advantage of being easy to install and replace, without any major network modification. They offer immediate protection, but require rigorous follow-up: the lifespan is limited (a few weeks to a few months depending on the model), and inadequate maintenance can reduce their effectiveness.

Filtration in retirement homes: prevention of Legionella

In retirement homes, controlling the risk of Legionella is a priority. Legionella develops particularly in domestic hot water networks when the temperature is poorly controlled or when deposits form in the pipes.

Anti-legionella filters constitute a barrier complementary to thermal or chemical disinfection. They prevent the passage of bacteria to distribution points (showers, sinks, kitchens).

This protection is essential for residents, often elderly or suffering from chronic diseases, who have increased sensitivity to respiratory infections. Their implementation also makes it possible to meet the regulatory requirements imposed on health and medical-social institutions.

UV treatment: effective disinfection without chemistry

Ultraviolet radiation (UV-C) disinfection is a technology known for its effectiveness against microorganisms (bacteria, viruses, fungi, protozoa).
UV light acts directly on DNA and RNA, preventing germs from reproducing and therefore contaminating water.

Its main assets :

immediate disinfection, without the addition of chemicals,
no change in the taste or smell of water,
absence of undesirable residues or by-products (unlike chlorine).

Modern UV lamps offer high power, an optimized spectrum and an extended lifespan. They are often used in addition to mechanical filtration to ensure maximum microbiological safety.

Prefiltration kits: limit the fouling of fine filters

The water of a network can contain many solid particles: sand, algae, limestone, sludge…
These impurities, while not dangerous to health, can quickly cradle terminal filters and reduce their lifespan.

Prefiltration kits are a first barrier. Equipped with cartridges of 5 μm, 1 μm or 0.5 μm, they effectively remove these particles and ensure:

better longevity of the terminal filters,
reduction of maintenance costs,
clearer and better quality water at the exit of the network.

These devices are delivered ready to install (wall mounting, simple connection) and designed for easy maintenance. Some cartridges are washable or removable, which facilitates regular maintenance.

Custom Prefiltration Chains (skids)

For large hospitals or establishments with specific needs, it is possible to set up pre-filtration skids.

These are compact modules grouping several filtration steps (large filters, multiple prefilters, activated carbon filters, etc.), dimensioned according to the quality of the inlet water and the uses, on the latter, we can also add a part with automatic chlorination to have bacteriologically controlled water (EBM).

The advantages :

• a turnkey solution that is easy to install,
• tailor-made design, adapted to the constraints of the site,
• an evolving system that can integrate new processing steps.
• These centralized installations make it possible to protect the entire internal network and to guarantee high quality water from the main distribution.

Maintenance and monitoring: a pillar of health security

No treatment device is effective without rigorous monitoring.

Regular maintenance of equipment is essential to ensure its performance over time:

• periodic replacement of terminal filters,
• cleaning and changing the prefiltration cartridges,
• verification and replacement of UV lamps,
• Microbiological and physico-chemical control of water.

Good monitoring not only ensures health safety, but also cost optimization: a filter well protected by pre-filtration lasts longer and requires fewer replacements. We can accompany you on the management of filter changes, do not hesitate to contact us.

Water treatment in hospitals and healthcare facilities is a global system that combines several complementary technologies: terminal filtration, anti-legional filters, UV disinfection, simple prefiltration or custom-made skid.

Well-sized, maintained and integrated in a comprehensive prevention approach, these devices ensure quality water, reduce infectious risks and contribute to the safety of both patients and staff.
