DESCRIZIONE
A system for removing parasites on fish flowing in a transport pipe from an inlet to an outlet, said system comprising a main pump (3), at least one treatment chamber (6a, 6b), a separation unit (12) fluidly coupled to a filter unit (14) and an intermediate pipeline (11), said intermediate pipeline (11) is arranged between the treatment chamber (6a, 6b) and the separation unit (12), said treatment chamber (6a, 6b) comprising at least one outlet for drainage of fluid (26a, 26b) and at least one inlet (44a, 44b) for injection of fluid, said inlet (44a, 44b) is arranged downstream said outlet (26a, 26b) The system is distinctive in that the separation unit (12) is situated in a plane (60) and said at least one treatment chamber (6a, 6b) is situated in a plane (61), said plane (60) is higher than said plane (61)so that the intermediate pipeline (11) having an upward inclination in the downstream direction. The invention also relates to a system for removing of parasites on fish with an injection unit (10a, 10b) having a plurality of slots (43a, 43b) arranged in said at least two slots zones (45a, 45b) around the circumference of the injection unit (10a, 10b), said slots (43a, 43b) being staggered relative to each other in the circumferential transverse direction, and to a method for removing parasites from the surface of fish using such a system.
