Abstract

Installation d'épuration d'eaux usées selon le brevet principal. Selon l'invention, cette installation est caractérisée en ce que le décanteur comporte une enveloppe pourvue de moyens d'évacuation de la phase liquide et entourant une enceinte amovible qui reçoit les eaux usées traitées par le réacteur et qui est susceptible de retenir lesdites boues, mais de transmettre ladite phase liquide vers l'extérieur. Epuration d'eaux usées.
