Especificações técnicas
The following table outlines the physical and chemical properties of our manganese sand filter media, benchmarked against leading competitors to ensure superior quality and performance.
| Propriedade | Especificação | Notes/Comparison |
|---|---|---|
| Physical Form | Black nodular granules | Similar to GreensandPlus and Pyrolox; dense and uniform for consistent flow. |
| Densidade a granel | 85-90 lbs/cu ft (1,360-1,440 kg/m³) | Lighter than Pyrolox Ore (120 lbs/cu ft) for easier handling and reduced shipping costs; comparable to Katalox Light for backwash savings. |
| Gravidade específica | 2.4-2.6 | Standard across manganese greensand alternatives like DMI-65 and Chinese MnO2 variants. |
| Effective Size | 0.30-0.35 mm | Optimized for fine filtration; matches GreensandPlus and exceeds broader ranges in Song Phung media (0.8-1 mm). |
| Uniformity Coefficient | <1.6 | Ensures even distribution; aligned with Clack Greensand Plus and Pyrolox standards. |
| Mesh Size | 18 x 60 | Common industry standard; compatible with Katalox Light and Pyrolox 20×40 grades. |
| Porosity | Approximately 0.45 | High surface area for enhanced catalysis, similar to GreensandPlus. |
| Packaging Options | 0.5 cu ft bags (44-50 lbs), 1 metric ton bulk sacks | Flexible for international shipping; NSF-compliant packaging like Vibrantz Pyrolox. |
Composição química

- Fe Content: ≤9%
- SiO2 Content: ≤18%
- Other Impurities (S, P, H2O): ≤0.4% each, ≤7% moisture
- Core Material: High-quality silica sand or natural manganese ore, ensuring stability in low-TDS waters unlike some uncoated competitors.
Dados de desempenho
Our manganese sand filter media delivers reliable contaminant removal with minimal operational overhead. Performance metrics are validated through cross-referencing with manufacturer benchmarks and international testing protocols.
| Metric | Value/Range | Notes/Comparison |
|---|---|---|
| Iron (Fe) Removal Capacity | Up to 1,200 grains/sq ft (or 833 mg/kg) | Comparable to GreensandPlus (700-1,200 grains/sq ft) and Pyrolox Ore; effective for inputs ≤35 mg/L. |
| Manganese (Mn) Removal Capacity | Up to 225 mg/kg | Matches Pyrolox and exceeds Song Phung for high-Mn waters. |
| Hydrogen Sulfide (H2S) Removal | Effective at 6x mg/L demand | Similar to Katalox Light; no by-products. |
| Arsenic (As) & Radium Removal | Requires co-present Fe/Mn; up to 90% efficiency | Aligned with GreensandPlus; pilot testing recommended for optimization. |
| Vida útil | 5-10 years | Longer than Song Phung (2-3 years); comparable to Katalox Light (7-10 years). |
| Filtration Efficiency | Down to 3-5 microns | Superior to standard sand; matches advanced media like Katalox Light. |
| pH Adjustment | Stabilizes at 6.5-8.0 | Raises low pH without additives, similar to Song Phung. |
Operational Parameters

- Maximum Temperature: No limit
- Vazão de serviço: 2-12 gpm/sq ft (5-30 m/hr); lower for high contaminants
- Taxa de retrolavagem: 12-30 gpm/sq ft (30-62 m/hr) for 40% bed expansion
- Profundidade da cama: Minimum 30 inches (762 mm) standalone; 15 inches each in dual-media (e.g., with anthracite)
- Regeneration: Catalytic oxidation (CO) with chlorine preferred; no mandatory KMnO4; intermittent regeneration (IR) optional
- Pre-Conditioning: Minimal; backwash and brief chlorine soak (0.5 gal 6% bleach/cu ft)
- Air Scour Option: 0.8-2.0 cfm/sq ft with reduced water backwash
