What is being procured?

Scope of work

La déshydratation des boues digérées de la STEP de Troistorrents date de la construction de la STEP et n’a jamais été renouvelée. Avec 34 ans, la presse à bandes et tous les équipements annexes (pompes, installation de floculation, tableaux électriques,..,) ont largement dépassés la durée de vie de 25 ans généralement admise pour les équipements électromécaniques. Actuellement, le degré d’automatisation peu élevé de la déshydratation implique pour chaque campagne de déshydratation (lancement, surveillance et arrêt) de nombreuses heures d’exploitation. De plus, la capacité de déshydratation étant faible (2m3/h), les campagnes de déshydratation sont longues, et il n’est pas possible de laisser fonctionner l’installation sans surveillance. En termes d’entretien et de maintenance, les coûts sont élevés car les équipements sont obsolètes. Les presses à bandes ne sont plus produites depuis longtemps et les pièces de rechange sont difficilement disponibles.

Le projet prévoit le renouvellement complet de l’installation de déshydratation y compris les

équipements annexes.

L'objet de la soumission consiste, au démontage des installations existantes, au dimensionnement, à la fourniture, au montage et à la mise en service d’un système complet de déshydratation des boues.
