Spiral Duct Sieve DF SSP/SSB

Spiral Duct Sieve DF SSP / DF SSB is used for mechanical separation of solid bodies contained in sewage and industrial wastewater. The sieve is assembled either in indoor or outdoor ducts systems. Depending on type selected it may be equipped with perforated filtration part or slotted rotary drum.

Spiral Duct Sieve DF SSP/SSB
The wastewater flowing into the filtration part which consists of either perforated plate, or slotted drum sieve. The clearance applied is between 1,0-10,0mm which ensures efficient separation of screenings meeting the investor’s demand.
SSP: Screenings held on the perforated sieve are swept by the brushes integrated with worm conveyor. The contaminated material is then transported up where it is flushed and drained by the compressing-draining segment. The screenings are transferred outside the sieve through the discharge duct.

SSB: The filtering part is the slotted sieve assembled on rotary drum integrated with the worm conveyor. After achieving assumed contamination level the drum starts rotating and water-mechanical cleaning process commences simultaneously. The screenings held are dropped to the worm conveyor which transports them up where they are flushed and drained in compressing-draining segment. Transferring screenings outside the sieve is performed through the discharge duct.
