APPLICATION DESCRIPTION
This is the sewage treatment works for the small town of Ballivor in County Meath, and is sited on the edge of the town. A full range of SKE Solutions equipment, as used in a typical works, is supplied, fulfilling all the screening and grit removal requirements. There are 2-off elevating spiral screens that remove screenings from the pumped flow, using a 6mm screen resolution. Screenings are washed, and elevated using shaftless spirals. The screenings are then discharged to a common conveyor, before delivery to a small hydraulic compactor. This compactor in turn discharges clean, dry screenings to a skip. Two Grit Traps elevate wet grit using air blower systems. The grit is then classified, and clean, dry grit is also discharged to the skip.

This plant is very similar to that used nearby at the village of Longwood. All equipment is well integrated and giving reliable operation on a daily basis.
