Silex Natural Filter Sand is used as last layer of sand in filter bed. Below silex sand, support pebbles are layered out to support sand layers.  Importance of filter sand, to work for physical treatment (catching the turbidity component suspended) in rapid filtration and for biological treatment in slow filtration. High quality filter sand requires the proper angularity, hardness, spherecity and size. Silex Sand improves efficiency by reducing retention time and head pressure loss with greater flow rates.
Advantages

• Filter Sand is all-natural, environmentally safe product
• Angular shape of the uncrushed filter sand promotes good flow and even distribution
• Reduces the load on downstream equipment
• Cost Effective

Size Available

• 2 mm - 3 mm
• 2 mm – 4 mm
• 1.5 mm – 3 mm
