Glass beads are used as back-up and borehole filter material.
 
MAJOR ADVANTAGES

  • Highest possible effective pore space through exact particle size and spherical shape
  • Optimal adaption of filter openings due to single grain filling of glass beads
  • Pump cleaning is not necessary
  • No disinfection before installation
  • Minimal, smooth surface leads to a deceleration of lead and manganese contamination
  • An optimal regeneration through large pore spaces No subsequent subsidences
  • Thanks to a high flowability it is possible to the fill the glass beads also in narrow spaces without danger of hang
  • Higher material strength of the glass beads in relation to the flint quartz
  • During camera researches wtihin filter wire pipes impurity, contaminat or sedimentation of iron ochre are very good visible
