Abstract

The waste water enters at a feed tank from which it is pumped to an aerator of the activated sludge type. After treatment the water is directed to a decanter which separates the residual materials and the mineral particles from the liquid phase; the mineral particles are sent by a drain pipe to the sludge beds. Taking up of the water in the aerator is effected by a tubular body, the upper portion of which has the shape of a reversed cone; it is fitted with a pliable tube leading to the decanter. The tubular body is connected to a low density flotation body. The picking up of the treated water and its removal to the decanter takes place at a constant rate so that the level in the decanter, and the dwell time are constant.
