An apparatus and a process for separating substances from an influent fluid by means of dissolved-gas flotation, in which a flotation tank has at least one fixed fluid inlet for the influent fluid and at least one mixture inlet for a fluid-gas mixture. Associated with the mixture inlet is a depressurization element for at least partial decompression of the fluid-gas mixture directly into the flotation tank, with the depressurization element being arranged essentially below the influent liquid inlet. The essential advantages of the invention are that, owing to the direct decompression directly below the flow of the influent liquid, a more efficient flotation process is effected. The losses after decompression can be kept low, and the gas bubbles formed can be immediately employed for flotation. |
