Anwendungen

Garnet filter media is versatile and widely used in water treatment processes where fine filtration is critical. Its high specific gravity allows it to form a stable lower layer in multi-media setups, complementing anthracite, sand, and gravel for optimized turbidity removal.

Key applications include:

  • Municipal Water Treatment: Pre-filtration for drinking water plants to reduce suspended solids and improve clarity.
  • Industrial Wastewater Filtration: Removal of fine particulates in manufacturing, mining, and oil & gas operations.
  • Desalination and Reverse Osmosis Pre-Treatment: Protects membranes by capturing micro-particles in high-turbidity feeds.
  • Swimming Pool and Aquaculture Systems: Maintains water quality by filtering out debris and algae.
  • High-Turbidity Environments: Effective in construction site runoff or river water purification for TSS reduction down to 5 microns.

Vorteile

Compared to traditional filter media like silica sand, our garnet offers superior performance for demanding international markets:

  • Enhanced Filtration Efficiency: Captures finer particles (10-20 microns) with deeper bed penetration, reducing filter runs and backwash water usage.
  • Durability and Longevity: High hardness and abrasion resistance minimize media loss over time, lowering replacement costs.
  • Chemical Inertness: Resistant to acids and alkalis, ensuring no leaching into treated water.
  • Operational Savings: Higher density reduces bed expansion during backwash, allowing for higher flow rates and energy efficiency.
  • Environmental Benefits: Naturally sourced, recyclable, and silica-free alternative to reduce health risks associated with silicosis.
