Abstract

L'invention concerne un procédé de traitement de l’eau salée d’un élevage aquacole, dans lequel : on réalise une première filtration de l’eau salée (7) pour en extraire des polluants sélectionnés dans le groupe comprenant des matières organiques, des solides en suspension, des phosphates,on réalise une deuxième filtration de l’eau salée (21) plus fine que la première filtration (7), pour en extraire des sulfates et des micropolluants sélectionnés dans le groupe comprenant des métaux lourds, des pesticides, des polluants présents à l’état de traces, eton renvoie l’eau ainsi traitée dans ledit bassin (1). (Fig. 1)The invention relates to a method for treating salt water from an aquaculture farm, in which: a first filtration of the salt water (7) is carried out in order to extract therefrom pollutants selected from the group comprising organic matter, suspended solids, phosphates, a second filtration of the salt water (21) finer than the first filtration (7) is carried out, in order to extract sulphates and micropollutants selected from the group comprising heavy metals, pesticides, pollutants present in trace amounts, andthe water thus treated is returned to said basin (1). (Fig.1)
