Anvendelser
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.
Advantages
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: Modstandsdygtig over for syrer og baser, hvilket sikrer, at der ikke sker udvaskning til behandlet vand.
- Operationelle besparelser: Højere tæthed reducerer sengeudvidelsen under returskylning, hvilket giver mulighed for højere flow og energieffektivitet.
- Miljømæssige fordele: Naturligt fremstillet, genanvendeligt og silikafrit alternativ til at reducere sundhedsrisici forbundet med silikose.
