Abstract

L'invention concerne un procédé pour dissoudre un gaz dans un liquide aqueux. Selon l'invention, on soumet d'abord le liquide à une pression réduite pour en éliminer les gaz préalablement dissous, entraînés ou produits in situ, et on dissout ensuite ledit gaz dans le liquide désorbé. Application : dissolution d'oxygène dans les eaux d'égouts pour leur épuration microbiologique.
