The invention relates to an aeration device (20) for aeration of a liquid. The aeration device comprises a plate (30) of a first material, said first material being permeable to air, said plate having inlet means (31) for inletting air into the plate and means for creating a flow of liquid across the plate of the first material, when said aeration device is immersed or submerged in a liquid. The plate of first material is stationary within the aeration device. The aeration device may moreover comprise a disc (12) arranged for being placed in parallel to the plate, but leaving a gap between the plate and the disc member, and the means for creating a flow of liquid across the plate of the first material may comprise means for rotating the disc member around a central axis through the disc member. Small or very small bubbles of air may be generated by the combination of air permeable material and creation of a flow across the plate.
