Combined Pre-Treatment Unit type CC/Q
1. Technological Purpose
Combined Pre-Treatment Unit type CC/Q consists of a screw screen, a decanting tank, a sand
extracting screw and a grease scraper.
Sewage from civil or industrial waste water treatment plants has to be pre-treated before
being transferred to any purification system. The CC/Q carries out different processes: dewatering and compacting of screened solid waste in the screen compactor, separation of
sand by the sand classifier and removal of floating, greasy matter by air / mechanical
removal system. During the process solids, sand/grit and greasy matter present in the
sewage are removed in order to avoid overloading of the downstream treatment system.
Waste water enters the unit and is processed by means of separation by screw screen. The
separated debris are de-watered and compacted by the screen compactor. Subsequently, a
sedimentation process and the extraction of the sand or grit takes place. In the CC/Q 20model and above, an additional degreasing device works to remove fats and suspended
solids using an aeration system and a special mechanical scraper.
