Abstract

PRECIS DE LA DIVULGATION :

L'invention se rapporte à un procédé pour le traitement de liquides, notamment d'eaux, par décantation à lit de boue pulsé. Le liquide à traiter est en contact avec le lit de boue et traverse ce dernier avec une vitesse ascensionnelle. On confère au liquide à traiter, à son entrée dans l'appareil et lors de sa progression dans le lit de boue une direction d'écoulement inclinée sur l'horizontale. L'inclinaison est telle que les boues constituant le lit sont amenées à se déposer en donnant naissance à des courants préférentiels du liquide et des boues. Les courants favorisent la tendance au tassement des boues. Le procédé permet, suivant les cas, soit d'opérer sans modifier la vitesse ascensionnelle moyenne du liquide à traiter, avec un lit de boues de forte concentration en matière de suspen-sion et donc d'obtenir une qualité d'eau traitée supérieure, soit d'augmenter sensiblement la vitesse ascensionnelle du liquide à traiter, sans obtention d'une qualité d'eau équivalente, soit de combiner ces deux possibilités.
