Successful concept for municipalities and industry: environmentally conscious disposal, massive reduction in the amount of residual sand that has to be disposed of, lower transport costs, improved gas production in sludge digestion.
Unique Features
- Robust, thick-walled spiral
- Spiral and agitator are mounted on the drive end only, no submerged bearing
- No separate outlet required for organic matter
- Less fine grit discharge in the effluent and low wash water consumption
- Less turbulence in the washing zone and thus low ascent speed of the sand grains
