People and data safety

Water on a site


is a complex system, which can not be summurized to its consumption, its direct cost or a snapshot of its quality.

It is an endangered resource, interdependent of the other utilities and all the processes inside the factory (to heat up, to cool down, to dilute, to carry, to cook, as an ingredient…)

Making this complexity and this value visible, is activating


A lever of industrial and environmental performance

Tested and approved, our clients testify

We have been looking for a long time for a partner who could understand our specific needs and helps us shape our concept. Aquassay's competencies and reactivity were key in achieving this first step of adding artificial intelligence into our reverse osmosis systems. We are very pleased with this first experiment and looking forward to further enhancing the model. Very soon our RO units will be able to guide the operators in executing the right preventive maintenance tasks.

Nous avons été très satisfaits de la prestation d’Aquassay durant toute les étapes de notre projet (définition du cahier des charges, appels d’offres et suivi des travaux). Aquassay nous a apporté une vraie valeur ajoutée en nous proposant des procédés ou des solutions techniques parfaitement adaptées à nos exigences. Nous avons également particulièrement apprécié le haut niveau de compétences des personnes rencontrées.

En 2018, un premier « démonstrateur » digital a été mené sur le site de Olsztyn, en Pologne, avec Aquassay. De l’acquisition des données à la modélisation de certains usages de l’eau comme la déminéralisation et la gestion des tours aéro-réfrigérantes (TAR), le digital nous permet d’entrevoir collectivement des nouvelles sources de progrès. Le digital accompagné d’experts de l’eau permet en effet de diffuser les enjeux au sein des organisations et de donner des moyens au plus près des utilisateurs afin qu’ils puissent exercer leurs responsabilités dans des conditions de succès.
