Arsenic Removal Technology for Drinking Water: BKsorb Iron Hydroxide Filter Media

Iron Hydroxide Filter Media BKorb is a highly efficient adsorbent for arsenic removal in drinking water, offering the following significant advantages:

1. High Selectivity and Adsorption Capacity: Exhibits extremely high selectivity for arsenic (+3 and +5), with an adsorption capacity of 6-14 g/kg (as As). Its large specific surface area (approximately 300 m2/g) provides adsorption performance 4-10 times greater than competing products.

2. Stable and Reliable Effluent: Consistently reduces arsenic concentration in water to below 0.01 ppm (even lower than 3 ppb), unaffected by common competing anions.

3. Easy Operation and Low Maintenance Cost: Requires no chemical additives, operates without electricity, has a long service life (1.5-5 years), simple installation, no complex operations, easy backwashing, and produces no arsenic-containing sludge or wastewater.

4. Safe and Environmentally Friendly: Made from safe materials, certified to NSF/ANSI Standard 61, with no pollutant leakage and no secondary pollution.

5. Wide Range of Applications: Suitable for drinking water, groundwater, wastewater treatment, aquaculture, and particularly ideal for arsenic removal in drinking water.
