SPIRAC has experience in wastewater treatment for the pulp and paper sector including aspects of system design and complete sludge management systems. 

Our products and solutions will take care of :

  • Coarse rejects conveying and dewatering
  • Pulp and sludge conveying
  • Waste stream separation
  • Grit classification and conveying
  • Various effluent screening systems
Inks or adhesives have an effect on the wastewater characteristics in corrugating plants and different methods of production or raw products in pulp mills can change the nature of the wastewater stream. 
 
We know that accidents do happen and armed with this knowledge, our robust products and solutions are designed to consistently perform. 
 

Technical details

  • Shaftless screw conveyor
    The unique design of the shaftless screw allows for higher filling rates and lower RPMs - resulting in less wear, and consequently less demands for repair and down time. The spirals themselves can be made of many different materials, however the primary material is high tensile micro-alloyed steel (HTMAS) - a special steel from Sweden with mechanical properties that deliver incredible strength to the SPIRAC spiral.
  • No intermediate or end bearings
    The more moving parts in a piece of equipment, the more faults that can occur. By eliminating intermediate and end bearings, the need for major maintenance work is reduced. It also allows for more efficient and direct transfer into another conveyor - whether that be horizontal, inclined or vertical.
  • DURAFLO® Type SPX liners
    SPIRAC's proprietary liner - DURAFLO® Type SPX - has been designed specifically to ensure low wear and a long life. A combination of material thickness and formulation gives DURAFLO® Type SPX its unique wearing characteristics. DURAFLO® Type SPX has been developed over many years, and is one of the key features which ensures that SPIRAC conveyors stand as the industry leader. The DURAFLO® Type SPX liner also has a built-in wear indicator with a snap-in, snap-out feature, making it as painless as possible when the time comes to replace it.
  • Totally enclosed troughs
    SPIRAC shaftless screw conveyors come in horizontal, vertical and inclined configurations, and options for either a U-trough or octagonal (OK) trough. All varieties are totally enclosed with elastomeric seals and gaskets, ensuring there is no spillage of the material being conveyed and that odours are completely contained.
  • Direct drive
    Further reducing the downtime and expense that comes along with regular repairs and service, SPIRAC's direct-drive design allows a clean and efficient transmission - without the required maintenance of belt and chain drives.
