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.

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
