SPIRAMATIC Fine Drum Screens VSA and VSA MBR - 1

Waste Water Treatment 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 in a fabricated tank. 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 a discharge chute into a container or compactor. Triple face seal for maximum capture efficiency of fine solids; Spray bar installed on the outside of the screen basket, thus enabling optimum capture of small solids; Cleaning brush fitted on the screen maintains screen surface clean; Durable brush attached to the flighting on the auger trough sweeping even smallest solids into auger trough for removal; 33 Large, robust, self-lubricating bronze bushing (no lubrication pump or maintenance required); 33 Low energy consumption and limited maintenance.
