Groundwater Arsenic Removal Iron Hydroxide Arsenic Removal Filter Media
Iron Hydroxide Arsenic Removal Filter Media BKsorb is currently one of the mainstream adsorption materials in the field of groundwater arsenic removal, particularly suitable for rural areas, small water plants, and single-village single-well water supply systems, and can also be used for advanced treatment in municipal water plants. Iron Hydroxide Arsenic Removal Filter Media BKsorb has an extremely high adsorption efficiency for arsenic, with the following performance in actual operation:
Core Data on Adsorption Efficiency
| Indicator | Data Performance |
|---|---|
| Actual Adsorption Rate | 80–95% (for total arsenic) |
| Inorganic Arsenic Removal Rate | ≥95.4% (effective for both As(III) and As(V)) |
| Effluent Concentration | ＜0.01 mg/L (10 ppb), with a minimum of ＜0.001 mg/L (1 ppb) |
| Adsorption Capacity | 6–14 g/kg (based on As), which is 4–10 times that of conventional arsenic removal resins |
| Operational Lifespan | 1.5–5 years of continuous use without replacement or regeneration |
Technical Parameters and Performance
| Indicator | Parameter Range |
|---|---|
| Main Component | β-FeOOH / Fe(OH)?, Fe content ≥60% |
| Specific Surface Area | 300 m2/g |
| Particle Size | 0.2–2.0 mm |
| Adsorption Capacity | 6–14 g/kg (based on As) |
| Applicable pH | 5–9, with peak adsorption pH at 6.5–7.5 |
| Filtration Flow Rate | 10–20 m/h (or 10–20 BV/h) |
| Empty Bed Contact Time (EBCT) | ≥3 minutes |
| Lifespan | 1.5–5 years (depending on raw water arsenic concentration) |
| Effluent Arsenic Concentration | Stable <0.01 mg/L (10 ppb), compliant with drinking water standards |
Process Steps
Filling: Load BKsorb filter media into the filtration tank, recommended height 80–160 cm.
Adsorption Filtration: Control the water flow rate to ensure a contact time ≥3 minutes.
Backwashing: When pressure drop reaches 0.5 bar or clogging occurs, backwash at a flow rate of 25 m/h for 5–10 minutes.
Replacement: Replace the filter media directly after adsorption saturation, no regeneration required.
Applicable Scenarios
Rural groundwater arsenic removal and upgrade projects (can operate without electricity or technical personnel)
Single-village single-well water supply systems
Small centralized water supply stations (treatment capacity 0.5–5000 m3/h)
Emergency water supply and post-disaster water recovery systems
Advantage Summary
No pre-oxidation required: Directly adsorbs As(III) and As(V), simplifying the process.
No chemical additives: Pure physical adsorption, no secondary pollution.
Low operating cost: Treatment cost per ton of water is approximately 0.15–0.35 RMB.
Simple maintenance: No electricity needed, no sludge production, suitable for remote areas.
If you need specific dosage calculations, filter tank design recommendations, or case references, please provide the raw water arsenic concentration, treatment water volume, and site conditions, and I can help estimate the filter media dosage and replacement cycle.
