A method and equipment for removing ammonia from effluent, flue or waste fluids that include oxygen. The method includes at least the following stages: Part of the fluid () is conveyed to a decomposition/oxidation unit () and part of the fluid () is conveyed to a by-pass unit (); part of the fluid () including ammonia is oxidized in the decomposition/oxidation unit () of ammonia; the fluid (H) that was oxidized in the decomposition/oxidation unit () and the fluid () that was conveyed to the by-pass unit are mixed in a mixing unit () to form a fluid mixture (S), and the fluid mixture (S) is conveyed to a selective reduction unit ().
