2 - 4 mm Filter Sand

2 - 4 mm Natural Sand Filter Media

Overview:
Natural sand with a particle size range of 2–4 mm is a highly efficient and commonly used granular filter media in water and wastewater treatment systems. Sourced from riverbeds, quartz-rich deposits, or processed sand quarries, this media is prized for its natural hardness, uniform granule size, chemical inertness, and excellent filtration capability.

 

  • Grain Size: 2–4 mm
    Optimally sized for effective removal of suspended solids, dirt, algae, and organic impurities in multi-layer filtration beds.

  • Specific Gravity: ~2.6 g/cm³
    Ensures it settles well in layered beds and resists displacement during backwashing.

  • Effective Size (D10): Typically between 2.1 and 2.5 mm
    Critical for determining filtration speed and performance.

  • Uniformity Coefficient (UC): ≤ 1.7
    Ensures consistent filtration across the media bed and prevents channeling.

  • Hardness & Durability:
    Composed mostly of silica (SiO₂), giving it superior strength and a long operational life.

  • Water Treatment Plants (WTPs)
    Acts as a primary or intermediate layer in dual or multimedia filters.

  • Effluent & Sewage Treatment Plants (ETPs/STPs)
    Used in tertiary treatment units to polish treated water before discharge or reuse.

  • Swimming Pools & Aquaculture Systems
    Maintains water clarity and health by trapping fine particles and organic matter.

  • Industrial Process Water Filtration
    Protects machinery and systems by removing fine impurities.

✅ Natural & Eco-friendly – No synthetic processing involved.
✅ Chemically Inert – Does not alter water pH or chemistry.
✅ Cost-effective – Long-lasting and requires minimal maintenance.
✅ High Dirt Retention Capacity – Ideal for high-volume filtration systems.
✅ Excellent Backwash Recovery—Restores filtration capacity with minimal media loss.Accordion Content

    • Recommended as a middle or bottom layer in multimedia beds depending on system design.

    • Often layered above 4–8 mm gravel and below 0.5–1 mm fine sand or anthracite.

    • Bed depth typically ranges from 300 to 600 mm, depending on flow rate and application.

  • Packaging: 25 kg / 50 kg HDPE bags or jumbo bags

  • Availability: In bulk quantities for municipal and industrial projects

  • Pre-washed & Sieve Graded: Ready to use

  • Conforms to IS: 8419, AWWA B100, and NSF/ANSI standards (if applicable)
