Abstract

An overflow device for a tank of liq. of the type which comprises an intake funnel mouthpiece in a horizontal plane with the funnel outlet pipe to a downstream outflow channel. The mouthpiece is constantly supported, pref. by a float assembly, at a level very near to the surface of the liq. The mouthpiece can be adjustably submerged below the surface to a predetermined depth related to the rate of overflow required. Used for adjusting the level at which a tank discharges by overflow. Partic. for periodic take-off from a combined aeration and settlement tank for treating waste water. Overflow discharge can be restricted to non-aeration periods so that there is no danger of discharging turbid water.
