Compact screening and sand separation device type SPS
The interlocked device for mechanical removal of screenings and sand consists of a spiral screen for separating screenings, integrated with the screenings dewatering press and a sand separator for removing sand. The entire purification process is closed and airtight.
-
the device allows for effective simultaneous removal of screenings and sand
-
screenings and pen separation process is closed and hermetic
-
screenings dehydration and concentration to approx. 40% of dry matter
-
fully automatic device
-
the device is made entirely of acid-resistant steel
-
small dimensions
1. Sieve integrated with the screenings press.
The sieve is mounted on the front of the device. In this zone, there is an inflow trough with a spiral channel sieve. An overflow pocket is installed in the inflow trough, which protects the device against flooding. Screenings are removed by means of a shaft screw conveyor that transports them to the bucket. Before they are poured out, the screenings are flushed with pressure through nozzles and compacted. The cleaned sewage from the screenings falls into the sand separator chamber.
2. Sand separator.
The sand separator is mounted in the second part of the unit. After separating the screenings, the wastewater falls into the hermetic chamber of the sand separator, where sand particles are deposited (sand sedimentation and separation). Sand particles settling at the bottom of the funnel are moved to the bucket by a shaft screw conveyor. After separating the screenings and sand, the wastewater can be directed for further treatment.
