Le terme "hydro-nettoyant" englobe une variété de technologies utilisées dans le traitement environnemental et de l'eau, toutes visant à éliminer les impuretés et les contaminants des sources d'eau. Un exemple notable est le système de flottation par air dissous (DAF), un procédé très efficace utilisé dans un large éventail d'applications, du traitement des eaux usées municipales au nettoyage des effluents industriels.
Baker Hughes Process Systems, un fournisseur leader de solutions environnementales, propose un système DAF sophistiqué réputé pour son efficacité et sa fiabilité.
Comprendre la flottation par air dissous (DAF)
Le DAF utilise le principe de la flottation à l'air pour éliminer les solides en suspension et autres impuretés de l'eau. Le procédé consiste à saturer un courant d'eau sous pression avec de l'air, formant de minuscules bulles d'air. Lorsque la pression est relâchée, l'air dissous forme des microbulles qui se fixent aux particules dans l'eau, les rendant flottantes et leur permettant de remonter à la surface. Un mécanisme d'écrémage élimine ensuite les solides concentrés, laissant un courant d'eau plus propre.
