Filtering Wastewater Bar Screen , Mechanical Bar Screen Wastewater Long Service Life
Description:
Mechanical Bar Screen also called as rainwater screen, is widely
used to block and get rid of floating debris in rainwater pump
station, wastewater pump station, water supply pump station and
influent pump station of sewage treatment plant municipal
wastewater treatment. Residue sizes larger than bar spacing get
blocked by the screening surface while sewage flowing by, the tines
of rake tooth plate go deep into the screen space. Residue blocking
the screen surface will be raked up to the top by rake tines, under
driven of driving chain and get discharged by gravity as they reach
the top of the discharge outlet. Residues dropped from discharge
outlet will fall into the conveyor or trash car for further
processing.
Applications:
· rainwater pump station
· wastewater pump station
· water supply pump station
· influent pump station of sewage treatment plant municipal
wastewater treatment

Advantages:
· Resistance to mechanical and hydraulic overloads due to high
tensile design in comparison with other types of mechanized
screens;
· High hydraulic efficiency achieved by using tear shaped bars that
cause a pressure gradient to the mesh and across the bar spacing;
· Tear shaped profile as well protects the screen from waste
jamming inside the filtering mesh. By using this design, such
blockages can be removed by rakes allowing the screen operate
freely;
· High reliability achieved by the absence of the rotating parts in
the submersible part;
· Submersible parts like casing, bars, chains and rakes are made of
stainless steel to improve corrosion resistance in aggressive
environments of wastewater;
· Improved ergonomics: maintainability of the screen due to
accessibility of the main units in operation and screen lifting
without demounting.
