The WASTEMASTER TSF2/3 Combined Pre-Treatment Plant consists of a screw screen, a decanting tank, a sand/grit 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 kind of purification system. The WASTEMASTER TSF carries out different processes: de-watering and compacting of screened solid waste, separation of sand/grit and removal of floating, greasy matter.
Function
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 plant and is processed by means of separation by screw screen. Subsequently, a sedimentation process and the extraction of the sand or grit takes place. In the TSF3-model an additional degreasing device sees to the removal of fats and suspended solids using an aeration system and a special floating scraper.
