An intake distributor for a settling tank filter with horizontally arranged filter elements which are located one above the other on a vertical hollow shaft arranged centrally in the tank while at the upper end of the inner tank chamber there is provided an annular chamber which is coaxial with the axis of the tank. This annular chamber on one hand communicates with the inlet and, on the other hand, through a coaxial annular slot or gap communicates with the interior of the tank. A suspension comprising a carrier liquid and a filter substance or an auxiliary filter means is passed through the annular chamber or annular slot in the interior of the tank, and the filter substance or auxiliary filter means while being circulated is settled on the filter elements. The inlet to the annular chamber is divided into at least two branches which lead at equal angular distances into the annular chamber. The flow cross section of the annular slot is considerably less than the flow cross section of the inlet. In the inner tank chamber outside the annular slot there are provided deflector members for the suspension leaving through the annular gap which deflector members serve for reducing the energy and speed of the flow.
