摘要:
A method to clean a treatment water containing brackish or sea water and further containing a veterinary product for aquatic animals, the method comprising the steps of: moving the treatment water, from a treatment aquatic area in which the aquatic animals are treated, toward a reaction vessel, performing a first degradation step of a portion of the veterinary product from the moved treatment water in the reaction vessel by an advanced oxidation process comprising introducing ozone and a basic substance, to obtain a reacting treatment water, performing a second degradation step of a remaining portion of the veterinary product in the reacting treatment water after the first degradation step, by retaining the reacting treatment water during a predetermined time and without introducing ozone, reducing the remaining oxidant species of the reacting treatment water, after the second degradation step, in order to obtain a clean treatment water.
