Product Information
QFS1 Coarse Filter Sand 99.7% (SiO₂), Quartz
Size: 1.13 - 2.46 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
- Durable and resistant to breakdown under high flow rates or backwashing conditions, ensuring long service life and minimal maintenance.
