Stainless Steel Screw Screen , Rotary Drum Screen In Wastewater Treatment Plant

Stainless Steel Rotary Drum Screen For Wastewater Treatment Plant
 
Screw Screen is designed for removal of screenings within wastewater prior to being received
 
by the main treatment process. Removal of such screenings minimises blockages of
 
downstream treatment processes. The inlet screw screen works by a screw mechanism which
 
rotates to lift the screenings out of the inlet channel and discharge them into a separate
 
container via a chute. ‘Screened,’ water then flows forward for further downstream treatment.
 
working principle
 
Screw screen to the horizontal equipment installed in the drains, the water from flowing into
 
the drum drum ends, the water flows through the grid gate slit, solid waste is filtered in the
 
grid baskets, cleaning arm with a finger in a circular motion when cleaning Grilling gap,
 
rake teeth extending into the grid, the solid was removed when the cleaning arm at the
 
highest point, by the action of water washing and slag plate, remove the garbage down from
 
the rake teeth, and fall into the garbage collection means a screw conveyor bucket, during
 
transport through the variable pitch action is dehydrated at the uppermost end of the
 
compression zone is squeezed, and squeezed the water is returned to the canal, and finally
 
into the garbage container or a successor device, and then processed.
