Natural Fine Sand

Fine Natural Filter Sand are used as topmost layer in filter bed. 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 fine sand requires the proper angularity, hardness, spherecity and size. Fine Sand improves efficiency by reducing retention time and head pressure loss with greater flow rates.

Advantages

• Fine 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
