Stainless Steel Screw Screen For ETP Projector Wastewater Treatment
Moreover, the lack of a lower bearing considerably reduces maintenance problems. The
screened material, before being discharged and sacked in a suitable container, is submitted
to compaction and de-watering involving an about 50% decrease in weight. The screw filter
is able to totally eliminate the suspended solids having a diameter bigger than the size of the
filtering gap, and considerably cut down the polluting load. Moreover, the completely closed
body, which is a peculiarity of this equipment, avoids the diffusion of bad smells. On request,
the screw filter can be provided with a system for the screened material washing with
nozzles and pressurized water.

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.
