Abstract

The present invention relates to a clean-water outlet, in particular for the discharge of clean water from SBR plants, having a float, a closable outlet element disposed thereon which possesses an inlet section for the supply of the clean water into the outlet element and having a discharge line connected to the outlet element for the discharge of the clean water. A reliably sealing clean-water outlet which possesses no mechanically actuated parts to close the outlet element, is provided in that the inlet section is designed in such a way that it can be closed by means of an air or gas cushion, that means are provided by means of which the air or gas cushion can be generated in the inlet section and that a deaerator is provided by means of which the air or gas cushion can be eliminated from the inlet section.
