Quick-Purge : Une solution rapide et efficace pour la réhabilitation des sols et des eaux souterraines

Integrated Environmental Solutions, Inc. (IES) se spécialise dans la fourniture de solutions innovantes et durables pour la réhabilitation des sols et des eaux souterraines. L'une de ses technologies clés est Quick-Purge, une méthode rapide et efficace pour éliminer les contaminants du sous-sol.

Qu'est-ce que Quick-Purge ?

Quick-Purge est une technique d'extraction de vapeur de sol sous vide (SVE). Elle utilise une série de puits à vide spécialisés installés de manière stratégique dans la zone contaminée. Ces puits aspirent l'air du sol, créant une pression négative qui attire efficacement les composés organiques volatils (COV) et autres contaminants de la matrice du sol vers le système d'extraction.

Comment fonctionne Quick-Purge ?

Le processus implique :

  1. Installation de puits à vide : Les experts d'IES sélectionnent avec soin les emplacements optimaux pour le placement des puits en fonction des conditions spécifiques du site et de la distribution des contaminants.
  2. Génération de vide : De puissantes pompes à vide sont connectées aux puits, générant une pression négative constante qui aspire efficacement l'air du sol.
  3. Extraction et traitement : L'air extrait contenant les contaminants est acheminé à travers un système de traitement pour éliminer les polluants avant d'être relâché en toute sécurité dans l'atmosphère.
  4. Surveillance et optimisation : IES utilise des techniques de surveillance avancées pour suivre l'avancement de la réhabilitation et assurer un fonctionnement optimal du système Quick-Purge.
