ASTIM - Model SAP - Sewage Acceptance Plant
Septic sludge is delivered to treatment plants by sewage trucks. Solid content must be separated from the septic sludge before it is discharged into the treatment plant. It is necessary to clean the sludge in order to keep the load for the treatment plant as low as possible during discharge of the septic sludge. Sewage Acceptance Plant “SAP” is used for mechanical treatment of septic sludge received from sewage trucks. After mechanical treatment, the sludge is directly discharged into the digester or into the inlet channel of the treatment plant.
The truck discharge is connected to the inlet flange of SAP. As sludge flows into the tank and through the rotating drum screen. All solids are kept by this screen and transported by the conveying system. Screenings press zone at the end of this conveyer dewaters the screenings in order to reduce the weight and volume. In addition, the screenings are washed and the press water flows back into the channel.
The whole cleaning process takes place in a closed system avoiding odor annoyance outside.
