The solutions that we offer adjust extremely well to variations in the quality of the water to be treated and the quantity of the load that it contains. Our treatment units are integrated into sea containers or mounted on SKIDs thereby reducing production times, installation times on site and civil engineering costs.
Sheet metal work and welding of the hydraulic structures are performed directly inside the container. Waterproofing is ensured by a seal made of special coatings that constitutes a perfectly monolithic block. It prevents water from coming into contact with the structures. The Coatings’ properties are always chosen in accordance with the project’s specifics (Health compliance certificate, WRAS, aggressiveness of reagents or water, etc.).


Whether in France or internationally, our water treatment experts are available to help you define the treatment unit that will best suits your needs.

Understanding how water disinfection works


After having been treated and filtered, water must undergo disinfection in order to maintain its properties and withstand colonization by micro-organisms.
Moreover, regulations often require that a minimum concentration of free chlorine be maintained throughout the distribution network.
The units can use one of several disinfection techniques depending on the objective:

  • Continual disinfection by injection of reagents (i.e. chlorine compounds)
  • Ozone disinfection
  • Ultraviolet (UV) disinfection


    Chlorine injection

    Chlorine is the most commonly used reagent for the continual disinfection of process water and in the production of drinking water. Chlorination is an easy to implement technique.
    When all pathogenic microorganisms (viruses, bacteria, algae, yeasts, …) have been eliminated, residual chlorine remains which ensures disinfection of water over time. This protects water during storage for example.

    Ozone injection

    Ozonation disinfects via trioxygen (O3 or ozone) induced oxidation. Several methods exist to produce ozone on site from ambient air or liquid oxygen. This technology has many advantages and is highly efficient. Ozone disinfection is generally picked for its cost effectiveness.

    UV radiation

    UV disinfection functions with lamps that emit UV-C rays into an irradiation chamber. These rays penetrate the nucleus of pathogenic microorganisms (germs, viruses, algae, moulds, bacteria, yeasts) present in the water and destroy them by stopping their DNA replication process.
    UV rays do not affect the water’s pH or its organoleptic characteristics such as odour, color or taste. The exposure intensity (a function of the lamps’ power, surface area and irradiation time, the water’s depth, …) is adjusted to the volume, flow rate and bacteria types.
