FS1 - FS1 Coarse Filter Sand

FS1 Coarse Filter Sand
FS1 Coarse Sand (1.2-2.4 mm, 99.1% Silicon)

FS1, with its high silica content exceeding 99%, is essential for specialised applications such as water filtration. It serves as a support layer in multi-layer filtration systems or as a coarse medium in primary filtration systems.

FS1 Coarse Filter Sand 99.1% (SiO₂),
Size: 1.2 - 2.4 mm 

  • Particle Size Uniformity
    • Ensures consistent filtration performance.
    • Optimised for applications requiring medium-grade filtration.
  • Flow Rate Optimisation
    • Balances particle removal efficiency with maintaining adequate water flow.
  • Resistance to Clogging
    • Larger particles reduce the risk of clogging compared to finer sands.
  • Supports Biological Filtration
    • In systems like slow sand filters, quartz sand provides a medium for microbial biofilm development, which helps in the biological breakdown of organic contaminants.
  • High Mechanical Strength, slightly lower than quartz
    • Durable and resistant to breakdown under high flow rates or backwashing conditions, ensuring long service life and minimal maintenance.
