Drinking Water Arsenic Removal Adsorbent BKsorb102 Iron Hydroxide Arsenic Removal Filter Media

Ferric Hydroxide Arsenic Removal Media BKsorb102 offers significant advantages in the field of arsenic removal from groundwater and drinking water due to its unique structure and adsorption properties.

The core advantages and features of BKsorb102 can be summarized into the following categories:

I. Efficient Arsenic Removal: High Removal Capacity and Precision

This is the most critical advantage of BKsorb arsenic removal media, directly determining whether arsenic removal meets standards:

• Simultaneous Removal of Divalent Arsenic: Without the need for complex pre-oxidation processes (or only simple pretreatment), it can simultaneously adsorb trivalent arsenic (As³⁺) and pentavalent arsenic (As⁵⁺) in water. It is particularly suitable for scenarios where arsenic forms are mixed in natural water bodies like groundwater, avoiding total arsenic exceedance caused by removing only one type of arsenic.
• High Adsorption Capacity: Due to its high specific surface area (approximately 300 m²/g) and abundant surface hydroxyl sites, its adsorption capacity for As⁵⁺ can reach 6-14 g/kg, and for As³⁺, 3-8 g/kg, far exceeding traditional filter media like quartz sand and activated carbon. This results in a longer service life (typically 1.5-5 years, depending on the arsenic concentration in the raw water).
• Compliant Effluent Precision: It can stably reduce arsenic content in water to **<0.01 mg/L**, not only meeting the requirement of arsenic ≤0.01 mg/L in China's "Sanitary Standard for Drinking Water" (GB 5749-2022) but also complying with the World Health Organization (WHO) drinking water standards, making it suitable for direct drinking scenarios.

II. Easy Operation: Strong Adaptability and Low Maintenance

It reduces equipment investment and operational thresholds, making it particularly suitable for small and medium-sized water plants or emergency treatment scenarios:

• Wide pH Range: No additional adjustment of water acidity or alkalinity is required. It operates stably within a pH range of 5.0-9.0. Since the natural pH of groundwater and surface water mostly falls between 6.0 and 8.0, it aligns well with this range, reducing the consumption of acid-base chemicals and operational steps.
• Good Process Integration: No complex equipment is needed. It only requires filling into conventional filter tanks and seamlessly integrates with existing water purification systems (such as pretreatment and terminal filtration). No large-scale civil modifications are necessary, making it suitable for upgrading old water plants or emergency arsenic removal projects (e.g., sudden pollution from high-arsenic water sources).
• Low Maintenance Costs: Daily maintenance only requires periodic monitoring of filtration pressure drop. When the pressure difference reaches 0.5 bar, backwashing at a flow rate of 20-26 m/h for 5-10 minutes can restore adsorption capacity. No chemical regeneration (such as acid or alkali washing) is needed, avoiding secondary pollution and additional costs from regeneration chemicals.

III. Economical and Energy-Efficient: Low Long-Term Operating Costs

It reduces costs throughout the entire lifecycle from "equipment investment - operation and maintenance - replacement":

• Low Initial Investment: No need to purchase complex devices such as oxidation equipment or regeneration systems. The media filling process is simple, reducing equipment and installation costs by 30%-50% compared to processes like reverse osmosis (RO) and ion exchange.
• Controllable Cost per Ton of Water: No chemical consumption (e.g., oxidants, regenerants) is required, and backwash water can be recycled. The long-term cost per ton of water treated is only 0.15-0.4 RMB, significantly lower than RO processes (approximately 1.0-3.5 RMB/ton).
• Long Replacement Cycle: Due to its high adsorption capacity, the media does not require frequent replacement, reducing downtime for replacements and the frequency of media purchases, thereby lowering operational labor and material costs.

IV. Environmentally Friendly and Safe: No Secondary Pollution, Easy Disposal

Ferric Hydroxide Arsenic Removal Media BKsorb102 meets the "safe and non-hazardous" requirements for drinking water treatment:

• Risk-Free Process: The adsorption process is a physical-chemical complexation reaction that does not release toxic or harmful substances (e.g., heavy metals, organic pollutants). No chemical additives are required, avoiding secondary pollution of water, and the effluent can be directly used as drinking water.
• Easy Disposal of Spent Media: The saturated media is highly stable, with arsenic firmly fixed on its surface (no leaching risk). It can be safely landfilled as general solid waste, without the need for special hazardous waste treatment processes, reducing disposal costs and environmental risks.
• Strong Compliance: Most products have passed international certifications such as NSF/ANSI 61 (Health Effects of Drinking Water System Components) and DIN EN 15029 (Filter Media for Drinking Water Treatment), meeting safety standards for drinking water treatment materials, ensuring greater peace of mind during use.

V. Feature Summary

The core value of Ferric Hydroxide Arsenic Removal Media BKsorb102 lies in its balance of "efficient arsenic removal + simple operation and maintenance + economic and environmental benefits." It is particularly suitable for scenarios such as groundwater arsenic removal, upgrading small and medium-sized water plants, and emergency water supply. It not only addresses water quality safety issues caused by arsenic exceedance but also avoids the high costs and operational pressures associated with complex processes, making it one of the preferred filter media in the field of drinking water arsenic removal today.
