The Ultra-Fine Incline Bar Screen is used for ‘ultra- ne screening’ where the removal of waste
material from 0.5mm up to 4mm in size is required in water and wastewater treatment.
The screenings are collected against a wedge wire screen eld and the waste is removed by means
of a multiple brush or rubber insertion rake system. The rakes pass over the wedge wire screen- BAR SPACING (E) (liters/sec)
eld and in doing so remove the entrapped screenings waste. The screenings waste is then MODEL
carried by the dual chain driven rake system up the debris plate and discharged at the top back 0.5 1 2 3 ϰ
end of the screen via the scraper system, and is expelled down the discharge chute for further IBUFS400 96 160 240 280 286
processing. IBUFS600 180 300 457 530 544
The screens are tted with a single motor-gearbox drive mechanism. IBUFS800 263 414 673 784 803
As an electrical standard the screens are timer based or as an additional option the screen drive
can be tted with a di erential level system, so that screens can be set to determine the frequency IBUFS1000 277 470 727 889 911
at which the rakes pass over the screen eld. IBUFS1200 352 601 932 1145 1170
Under normal operating conditions the controller (be it a PLC or di erential level controller) IBUFS1400 432 734 1137 1397 1430
ensures that the screen is operated intermittently, based on timers set for raking and standing. IBUFS1500 468 802 1242 1530 1559
Due to minimal maintenance, great reliability and ease of operation, this screen is extremely
popular in water plants wherever there is a diminutive allowance for technical operators. The
sizing of this screen is calculated to suit max Peak Wet Weather Flow. STANDARD
Screening waste discharge is processed to suit further waste removal systems, namely conveyors, CHANNEL CHANNEL INSTALLED
screw compactors or direct discharge into waste bins. MODEL WIDTH (A) DEPTH (B) DISCHARGE HEIGHT ( C) SCREENING ZONE POWER kW
