RTV Internally Fed Rotating Drum Screens are suitable for pre-treatment of both municipal and industrial waste water treatment, as well as MBR plants.

RTV Internally Fed Rotating Drum Screens are suitable for pre-treatment of both municipal and industrial waste water treatment, as well as MBR plants. RTV Drum Screens are made up of a tank and a spiral connected to the drum for conveying of screenings. The drum is manufactured from a perforated stainless steel sheet.

Function :

• The filter is fed through a nozzle placed on the machine inlet. It is cleaned by means of a washing system made up of a tube equipped with pressurized water spray nozzles.
• During operation, water is conveyed towards the outlet placed in front of the machine, while screenings are conveyed by the spiral to the outlet at the back of the screen.
• A special 5-degree incline angle towards the outlet contributes to dewatering the screenings while they are conveyed. The screen is equipped with by-pass nozzles which protect the filter from overflow.

Features :

• 11 different sizes available
• Standard perforated media spacing: 1 ~ 6mm
• Recommended spacing for MBR application: 1 ~ 3mm
• Full covering ensuring safe, dry, odour-free operation
• Screen manufactured from 304 L / 316 L SS

Benefits :

• High solids capture efficiency
• Appropriately placed flight segments constantly conveying solids towards discharge point
• External spray bar and brush preventing solids accumulation on external screen surface
• Pivots fully adjustable and replaceable without removing screen cylinder
• Screen design without running seals
• Low energy consumption and reduced maintenance
