The advantages of filter glass over filter sand

  • Filter glass is more efficient: Less bacwash is required and this reduces costs for water, energy and chemical treatment.
  • The angular to sub-angular particle shape of filter glass provides a 30% better filtering of the water than sand.
  • It removes finer particles from the water than filter sand of the same quality.
  • Due to the non-porous composition, it clumps less quickly than filter sand.
  • Filter glass has a lower density than sand, requiring 15% less media to fill an equivalent filter.
  • Filter glass lasts much longer than sand
