Mechanical Treatment of Wastewater at Sewage Pumping Stations

Summary

The most widespread methods of protection of pumping units against the ingress of large size garbage delivered to sewage pumping station with a wastewater flow are considered. An example of operation of the mechanized rake type screens RKE EKOTON® at the main sewage pumping station of the city of Seversk is made. The screens ensure the reliable removal of large size garbage from wastewater, owing to it the interrepair time of pumping unit operation increases. If before the reconstruction of the technological section 15–20 kg of garbage were removed from wastewater, after the adoption of new equipment this figure increased up to 50 kg/day. To compensate the costs of garbage evacuation the waste collected on screens is transported to the hydro-press for wringing that makes it possible to reduce it volume.
