De Menu Ventilation Ventilation of sewage treatment plants According to DIN 1986 sewage treatment plants are to be deaerated above the roof. This is usually done via the feed line to the sewage treatment plant. The minimum cross-section is DN 150. In the building, the pipe merges into the downpipe with a minimum cross-section of DN 100. The pipe is led out over the roof for ventilation. The higher the vent opening, the better the suction in the line. The air outlet opening should be protected with a hood. The ventilation takes place via the suction of air through the drain line. It is important to ensure that the run-out is free. In the case of downstream infiltration or the installation of non-return valves, an additional outlet for air intake must be created. If the installation is professional, there is a well-functioning ventilation system. An interruption of the ventilation, an open siphon or blockages can lead to unpleasant odors in the house. Concrete corrosion can occur if the ventilation is not carried out properly. An impairment of the cleaning performance is also possible. If ventilation over the roof is not possible or too far away, ventilation lines DN 100 must be led out from the tanks as short as possible to a suitable point at a maximum distance of 10 m and at a height of at least 2-3 m above the ground level. Alternatively, a wind-driven fan can be connected. An impairment of the cleaning performance is also possible.
