| Brackett Green CF200®
Band Screens have been developed to meet the increasing
requirement of waste water fine screening. Based
on the Band Screen supplied for raw water applications
and utilizing features developed for the Brackett Sewage
Drum Screen, the CF200® Band Screen has proved to
be a reliable and efficient fine screen both as a retrofit
for new installations on raw sewage and storm water.
Effective Wastewater Screening
By utilizing the Brackett Green
Center Flow Band Screen, the problem of solids bypassing
or carrying over experienced with conventional in-channel
band screens is overcome. With the ever increasing
demand for the improvement of discharge standards and
membrane applications, all unacceptable solids need to
be retained by the wastewater screening system and this is assured
by the Brackett Green CF200 and CF100 Band Screen.
Endless Band
The Brackett Green CF200
Band Screen has an endless band of screening panels
through which the water passes, Debris collected
on the mesh panels is raised to deck level and
removed by back washing.
Main chains, supported by two sprockets
above deck, carry the screening band. Drive is
provided by an electric motor through a shaft-mounted
reduction worm gear unit. Underwater, the main
chains run in guide sections fitted with the wearing
strips, located in a self-supporting fabricated frame.
Patented Mesh Panel and Seal
The CF200 Band Screen incorporates
the thick, molded polyurethane mesh panels with round
tapered holes. Sizes range from 2mm. diameter
to 6mm. diameter apertures. (US Patent No. 5407563)
This design of mesh panel has become an
established feature of Brackett Green sewage screens
eliminating the problem of hair pinning and blinding
experienced with conventional mesh materials such as
perorated plate or wire mesh.
To prevent solids bypassing the Band Screen,
the Brackett Green contact seal (UK Patent No. 002661)
is utilized.
Purpose designed Brackett
Green CF200 Band Screens are designed to suit each individual
application, with alternative flow patterns and construction
enabling tailoring to fit existing arrangements.
CF200 Band Screens can be constructed
in a wide range of sizes up to 4m wide and channel depth
up to 20m and can be readily installed in existing channels
with the minimum of civil work change. |
