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 a physico-chemical treatment unit functions


Decantation or sedimentation of the solids suspended in effluents is a standard procedure in the pre-treatment phase for the production of drinking water. This can be preceded by a coagulation and flocculation stage in order to increase the settlement of the suspended matter.
Settling may be static or lamella. Lamella sedimentation enables the settling surface area to be increased for a given unit.
This process is suitable for removing particles and suspended micro-organisms, certain heavy metals and organic chemicals with low solubility.


A coagulant and a chemical flocculant are injected into the raw water and mixed, forming flocs or precipitates that either settle or are trapped at a later stage of the treatment process. Effluent mixing is achieved in reactors equipped with pendulum agitators or directly on the production in line with static stirrers and mixing loops.
The different reactions use load neutralization, adsorption and, trapping mechanisms or chemical precipitation.
In the settling tank, flocs are transformed into diluted sludge that will be removed as a by-product.
