Sand & Gravel media

Sand and gravel media are granular filtration materials used in gravity and pressure filters to remove suspended solids, turbidity, and particulate matter from water. These media are typically installed in layered beds, where sand provides the primary filtration surface and gravel acts as a support layer that enhances flow distribution and prevents media loss.

🔹 Sand Media

• Made from high-purity silica or quartz

• Functions by mechanical straining, trapping fine particles as water passes through

• Available in graded sizes (typically 0.3 to 2.0 mm) to target different levels of turbidity

• Used as the primary filtration layer in both single and multimedia filters

🔹 Gravel Media

• Composed of natural, hard, and rounded stones

• Used as a support bed to:

  • Maintain the position of finer sand media

  • Ensure even water distribution

  • Prevent clogging of underdrain systems

• Installed in multiple layers (2 mm to 10 mm) from fine to coarse

Features

• Chemically inert and non-toxic

• Long-lasting with low maintenance

• Effective in removing particulates, algae, and sediment

• Ideal for potable water, industrial pre-treatment, and wastewater applications
