Sewage treatment plant SBFC

The sewage pre-treatment station with screw filter is installed for the treatment of sewage deriving from cesspools, Imhoff tanks and industrial plants, transported by means of tank trucks. The station, completely closed to ensure the maximum hygiene and safety, consists of a structure which is also used as sewage storage tank and a screw filter FC type. The operation is easy: the sewage entering the tank from the tank truck passes through a filtering screen and deposits on it the suspended solid matters and undergoes to a micro-screening. The trapped solid matters are lifted by a multifunction screw - consisting of a first scraping section and a second conveying & compacting section – and discharged into a specific container through a hopper. During the compaction, the drain waters are recycled to the tank.
