• Lower pressure drop than most other filter media
• Lighter weight than sand, requiring lower backwash rates
• High service flow rates for lower equipment costs and space savings
• High sediment reduction capacity for longer filter runs and less backwash water usage
• Reduced shipping cost due to light weight
• Can potentially double the capacity of existing sand filters

Efficiency:

• Removes suspended solids down to 20-40 micron range
• Larger particle size allows deeper sediment penetration for higher loading capacity
• Irregular shape prevents caking and blinding

Backwashing:

• Lower backwash rates due to lighter weight
• Better bed expansion for improved sediment release and rinsing

Iron Reduction:

• Although not designed for iron reduction, can trap iron flock after oxidation

Applications:

• Pressure or gravity flow systems
• Multi-media filtration systems
