High screenings capture efficiency

Ideal solution for MBR process

Proprietary face seal design eliminates bypass of hair and other fibrous materials

SPIRAMATIC VSA Fine Drum Screens consist of a rotating drum screen, a conveyor screw, and a compaction zone. Depending on the application, the fine screen drum can be made up of a set of steel bars – in which case the distance between the bars determines the desired slot width – or of a perforated sheet filter. The cylindrically shaped drum can be placed inside a channel or a fabricated tank.

Function

SPIRAMATIC VSA Fine Drum Screens wash, convey and dewater waste water screenings all in one unit. They are designed to wash out organic matter from screenings. Both screen basket and dewatering zone are self-cleaning. Rotating around its axis, the cylindrical filter conveys the screenings to a loading hopper placed in the centre. A set of spray nozzles washes the filter during operation. A screw, placed inside the conveying pipe, with its top in the discharge hopper, conveys the screenings towards the following treatment stages during which organic substances are washed out. Subsequently, solids are compacted and dewatered in the compacting and drainage area. Finally, solids are discharged through an discharge chute into a container or compactor.
