ANDRITZ rotating drums – Girapac and Girasieve - are enclosed, compact, and stand-alone units, mainly for full pre-treatment of wastewater entering municipal and industrial WWTPs. This type of rotating drum screen provides high solid/ liquid separation, as well as sieving, desanding, degreasing, and additionally, Girapac allows compacting and bagging of waste in one unit.
