Adsorptive Removal of Arsenic from Drinking Water Using BKsorb Iron Hydroxide Filter Media
The adsorption capacity and comprehensive benefits of BKsorb granular iron hydroxide arsenic removal media (typical models: BKsorb 102, BK-APM, etc.) in groundwater arsenic removal can be quantitatively summarized in the following table, which can be directly used for technical comparison and system design.
I. Adsorption Capacity (Measured Data)
| Parameter | Typical Value | Unit | Remarks |
|---|---|---|---|
| As(V) Adsorption Capacity | 4–14 | g/kg | Influent 200 μg/L, Effluent <10 μg/L |
| As(III) Adsorption Capacity | 3–6 | g/kg | No pre-oxidation required, one-step removal |
| Volumetric Adsorption Capacity | 3-11.5 | g/L | Based on packed volume |
| Effluent Arsenic Concentration | ＜0.01 | mg/L | Long-term stable compliance, often below detection limit |
| Specific Surface Area | ≈300 | m2/g | High surface area provides abundant active sites |
II. Comprehensive Benefits
Ultra-High Adsorption Efficiency: Adsorption capacity is approximately 5 times that of traditional adsorbents (activated alumina, resins), reducing material usage by 60–80%.
Simultaneous Removal of Both Valence States: Removes both As(III) and As(V) in a single pass, eliminating the need for pre-oxidation and simplifying the process.
Extended Service Life: Under typical groundwater conditions (50–500 μg/L As), lifespan ranges from 1.5 to 5 years, minimizing downtime for media replacement.
Zero Chemical Addition: No oxidants, acids, alkalis, or regeneration salts required during operation, producing no secondary wastewater or arsenic-laden sludge.
Low Operating Cost: Direct cost per ton of water is 0.15–0.45 RMB (including media purchase cost), saving over 50% compared to ion exchange.
Simplified System: Fixed-bed filtration suffices, with EBCT ≥3 min; skid-mounted or containerized systems can be commissioned within 3 days.
High Mechanical Strength: High particle hardness withstands routine backwashing at 30 m/h without breakage; no pulverization during long-term operation.
Preservation of Beneficial Minerals: Selectively removes heavy metals while maintaining calcium and magnesium levels, ensuring both taste and health benefits.
Authoritative Certification: Dual certification by NSF/ANSI 61 and DIN EN 15029, approved for direct use in drinking water.
Customer Validation: Proven in multiple projects with continuous operation, mature technology, and extremely low failure rates.
