  • Perfect and money saving solution for flow rates up to 100 l/s
  • Alternative 1: Separation of coarse material (> 3 mm) by use of fine screens with rotating spirals for solids removal
  • Alternative 2: Separation of coarse material (> 3 mm) by use of step screens
  • Spiral systems are including a dewatering zone for the solids.
  • Step screens could be accomplished by a solids compactor
  • Separation rate for sand up to 98 % (Ø 2.0 mm)
  • Removal and transport of the settled sand by a combination of two spirals
  • Hygienical storage of separated solids and sand by use of plastic bags
