Flottation naturelle. Elle est réalisée très simplement en faisant traverser de haut en bas une capacité, à faible vitesse, par la suspension à traiter. [...] Les matières flottantes se rassemblent à la surface sous le seul effet de leur faible densité, alors que le liquide interstitiel est évacué par le bas au moyen d’une cloison siphoïde. 1, record 2, French, - flottation%20naturelle
