Bahan filter garnet
Overview
Garnet filter media is a premium, granular material sourced from natural almandite garnet deposits. With its angular to sub-rounded particles and high specific gravity, it functions as the bottom layer in multi-media filtration systems, providing fine filtration for water and wastewater treatment. This media helps achieve clearer effluent by trapping suspended solids, and its robust properties ensure reliability in industrial, municipal, and commercial applications.
Features
- High hardness and abrasion resistance for extended operational life.
- Chemically inert with minimal acid solubility, preventing leaching into treated water.
- Uniform particle sizing with low uniformity coefficient for consistent performance.
- Available in various grades (e.g., #8-12, #30-40) to match specific filter designs.
- Environmentally friendly, as a natural mineral free from synthetic additives.
Applications
- Multi-media filters for potable water treatment in municipal systems.
- Industrial wastewater filtration, including removal of turbidity and fine sediments.
- Support beds for other media like anthracite or sand in high-flow setups.
- Pretreatment in reverse osmosis or ion exchange systems.
- Swimming pool and aquarium filtration for clarity and purity.
Advantages
- Enables higher filtration rates and longer run times compared to single-media filters.
- Reduces backwash frequency due to stable layering and resistance to attrition.
- Improves overall system efficiency by capturing finer particles than lighter media alone.
- Cost-effective over time through reduced replacement needs and energy savings in backwashing.
- Compliant with international standards, facilitating global trade and use in regulated markets.
