CST Rotary Screen

Tuesday, 07 August, 2012 | Supplied by: CST Wastewater Solutions

The latest CST Rotary Screen is suitable for high-efficiency screening of industrial and municipal wastewaters.

The design features all-stainless construction including base frame and it is fully enclosed for OHS odour and aerosol control. Advantages of the screen, enhancing durability, hygiene and serviceability, include: non-lubricated chains and nonmetallic drive sprockets; upgraded running wheel design; no mechanical parts in contact with screened solids; corrosion resistant; designed to handle high fat and grease loadings; self-cleaning; and optional wedgewire slots or perforated holes screening.

Typical industries to use the rotary drum screen include: general food processing (vegetables, fruit, coffee, starch processing), beverages (beer, wine, juice, soft drinks), slaughterhouses and abattoirs, tanneries, pulp and paper mills, textile plants, plastic manufacturers and many more industries.

Municipal treatment plants also use the screens for fine screening of raw sewage, pre MBR (membrane bioreactor) screening and sludge thickening.

The internally fed screen can use wedgewire or perforated hole drums. Wastewater passes into the internal feed tank before overflowing the weir onto the screen face of the drum. Solids are collected on the screen face, while the screened water passes through the screen face under gravity. Collected solids are discharged via the screen drum mouth.

The internal feed tank controls inlet velocities and distributes the flow evenly onto the screen face.
