Date Apr. 14, 1994.A sewage water installation has a discharge basin in which is arranged a screening unit linked to a back-and-forth movable cleaning carriage. The discharge basin (20) is subdivided by a partition (24) and by the screening unit (30) into a storage chamber (25') and an outflow chamber (25''). The storage chamber (25') is linked to an inflow pipe (26) and to an outflow pipe (27) and the outflow chamber (25'') is linked to an outflow pipe (28). In order to increase the storage volume and to reduce the throughflow speed, a retaining element (40) is arranged on the back-side of the screening unit (30), as seen in the direction of flow, inclined so as to form an angle therewith.</p> |
