Screen Compactors and Screen Extractors

Description and Working Principle

The Screen Compactor is a slimline combined machine consisting of:

• Screen: a drilled or wedge-wire metal screen section with mesh sizes 0.25 mm to 10 mm
• Conveyor: to elevate the captured solids out of the effluent and de-water by gravity conveying them towards the pressing zone
• Press: de-watering and compressing the screenings to give a volume reduction of up to 40%

The Screen Extractor comes without the pressing section.
The special design and structural simplicity of the Screen Compactor and Screen

Throughput rates up to 1000 m³/h.

Performance and Technical Features

RANGE AND PERFORMANCE

• Screen mesh size ranging from 0.25 mm to 10 mm
• Screen width ranging from 200 mm to 700 mm

Volume reduction up to 40%

DESIGN FEATURES

• Stainless steel housing
• Shaftless spiral screw made of carbon steel or stainless steel
• SFC = screen press for channel installation
• SFC/T = screen press installed in a self-supporting container
• SF = screen without press for channel installation
• ST/T = screen without press in a self-supporting container

ACCESSORIES

• Continuous bagging unit
• Heating for cold regions
• Screenings washing for faecal removal

SPECIAL SCREENS

High Solids Handling Screen Poultry Screen Screen with Bypass/Overflow

APPLICATIONS

Municipal waste water treatment plants:

• At entrance of plant with average mesh size of 5 mm
• As fine screen after coarse screen with average mesh size of 2 mm

Industrial effluent screening in:

• Tanneries at discharge (mesh size ranging from 0.5 mm to 5 mm depending on the application)
• Tomato processing at discharge before the reutilization of the water (mesh size ranging from 0.5 mm to 5 mm)
• Vegetable processing (peas, beans, potatoes) at discharge (mesh size ranging from 5 mm to 7 mm)
• White fish processing at discharge (mesh size ranging from 0.5 mm to 5.0 mm)
• Paper mills for removal of plastics, fibre, wood chips (5.0 mm or less)
• Airport services for discharging aircraft lavatories (mesh size 5 mm)
• Motorway services for lavatory discharge (mesh size ranging from 3 mm to 5 mm)
• Cattle and pig abattoirs before discharge (mesh size 5 mm)
• Dairy processing before discharge (mesh size 5 mm)
• Breweries before discharge (mesh size 5 mm)
• Drinks processing before discharge (mesh size ranging from 3 mm to 7 mm)
• Wineries before discharge (mesh size 2 mm)
• Textiles before discharge (mesh size 2 mm)
• Supermarkets before discharge (mesh size 5 mm)
• Alpine resorts before discharge (mesh size ranging from 2 mm to 5 mm)
• Tourist villages before the discharge (mesh size ranging from 2 mm to 7 mm)
• Chemicals before discharge (mesh size ranging from 1 mm to 7 mm)
• Cattle breeding before the discharge
• Pig farms (using a low flow rate of 5 to 10 l/s with mesh size of 0.5 mm Screen Press works as a sludge thickening unit)

Winery wastes at 0.5 mm to 3.0 mm

OPTION – (see related links at the top right of page)
– SF model, without compacting zone, has been developed mainly to be used in industries where solids do not require any forced dewatering (e.g. plastics)

Advantages and Innovative Features

• Absence of bearings
• No mechanical components in contact with the product handled
• Low speed
• Shaftless spiral, therefore no jamming or blocking even if with fibrous products
• Volume reduction up to 40% and more depending on the product
