Abstract

L'invention vise un procédé et une installation pour l'épuration des eaux usées, notamment contenant des substances en suspension et en émulsion. Selon ce procédé on place une masse filtrante composée de grains élastiques dans une enceinte de filtrage et de l'eau brute à épurer est envoyée à travers cette masse filtrante de bas en haut à une vitesse assurant le degré d'épuration requis, tandis que la régénération de la masse filtrante s'effectue par écoulement de l'eau brute à travers la masse filtrante de haut en bas. L'enceinte d'épuration 4, 6, 8 de l'installation est divisée, par des plaques de filtrage 5a, 5b montées à demeure, en une enceinte inférieure de réaction 4, une enceinte médiane de filtrage 6 et une enceinte supérieure d'eau 8. L'admission de l'eau brute 22, l'alimentation des produits chimiques de floculation 25 et l'évacuation de l'eau boueuse rinçant les substances polluantes 22 se font du réservoir 33 tandis que l'évacuation de l'eau épurée s'effectue par le sommet du réservoir. La masse filtrante 7 qui est placée dans l'enceinte de filtrage se compose, avantageusement, de matériau au grand coefficient de cavité, souple et mousse.
