Abstract

L'invention a pour objet des procédés pour épurer l'eau, notamment l'eau des bassins d'aquaculture. Un bassin 1 d'aquaculture selon l'invention comporte une rangée de générateurs de bulles 3, par exemple de tuyères, qui injectent dans le bassin une émulsion d'eau et de bulles d'air et qui créent un courant horizontal. Une goulotte 5 recueille par écrémage la mousse 7 formée par les bulles qui remontent en surface en entraînant des déchets. Une application est l'épuration continue des bassins d'aquaculture permettant d'utiliser ceux-ci en cycle fermé, avec un apport d'eau très réduitThe subject of the invention is processes for purifying water, in particular water from aquaculture ponds. An aquaculture basin 1 according to the invention comprises a row of bubble generators 3, for example nozzles, which inject into the basin an emulsion of water and air bubbles and which create a horizontal current. A chute 5 collects by skimming the foam 7 formed by the bubbles which rise to the surface, entraining waste. One application is the continuous purification of aquaculture ponds making it possible to use them in a closed cycle, with a very reduced water supply.
