An apparatus and a method for removing a carbonate from a zinc-nickel plating solution are provided to prolong the life of the plating solution, minimize loss of the plating solution, increase productivity, and reduce an environmental load by cooling the plating solution, separating a carbonate from the plating solution, and reusing the carbonate separated plating solution. An apparatus(100) for removing a carbonate from a zinc-nickel plating solution comprises: a cooling tank(110) for receiving a plating solution from a plating tank(10) to cool the plating solution; a solid-liquid separator(120) for receiving a plating solution discharged from the cooling tank to separate a carbonate contained in the plating solution by the action of centrifugal force; a plating solution storage tank(130) and a carbonate storage tank(140) for respectively storing the plating solution and carbonate separated in the solid-liquid separator; and first and second control parts installed in the cooling tank and the solid-liquid separator respectively to control supply of the plating solution of the cooling tank, and control the operation and discharge of the solid-liquid separator. The apparatus further comprises a water level gauge(116) which is installed on the cooling tank, senses a level of the plating solution supplied, and is closely connected with the first control part.
