Removal of bulky screenings and sediments such as sand, grit and debris in pumping stations or in the inlet area of wastewater treatment plants to protect downstream installations.

The Passavant® Cable Operated Bar Screen COB, supplied by Aqseptence Group, is employed as a coarse or fine screen for the mechanical pre-treatment of wastewater. It is an outstanding solution due to its high cleaning performance and its intelligent PLC control system. As the cleaning process can be repeated as often as necessary in any position, the machine is able to efficiently remove even extremely bulky screenings, sand deposited in front of the screen, or screenings trapped between the screen bars, which impede the downwards movement.
