The Incline Bar Coarse Screen (IBCS) is used for `coarse screening’ where the removal of waste material between 15mm and 100mm in size is required in water  and wastewater treatment.

The screenings are collected against a taper bar screenfield and the waste is removed by means of a multiple rake system.  The rakes pass over the screenfield and in doing so remove the entrapped screenings waste which caught between the taper bar.  The screenings waste is then carried by the dual chain driven rake system up the debris plate and discharged at the top back end of the screen by the scraper system, moving down the discharge chute for further processing.

The screens are fitted with a single motor-gearbox drive mechanism.

As an electrical standard the screens are timer based or as an additional option the screen drive can be fitted with a differential level system, so that screens can be set to determine the frequency at which the rakes pass over the screenfield.

Under normal operating conditions the controller (be it a PLC or differential level controller) ensures that the screen is operated intermittently, based on timers set for raking and standing.

Due to the 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 PWWF.

Screening waste discharge is designed to suit further waste removal systems, namely conveyors, screw compactors or direct discharge into waste bins.
