Abstract

L'invention concerne un procédé de régénération de liquides de rinçage usés contenant des résidus de peinture, dans lequel a) on injecte du CO2 sous pression dans le liquide de rinçage usés pour abaisser le pH au point isoélectrique de façon à faire coaguler au moins une partie des résidus de peinture ; b) on sépare les résidus de peintures coagulés du liquide ; c) on récupère le liquide de rinçage débarrassé des résidus de peintures coagulés.
