BK Sorb Granular Iron Hydroxide Arsenic Removal Filter Media

BKsorb Granular Ferric Hydroxide Arsenic Removal Media is applied in the field of drinking water arsenic removal. Its adsorption saturation cycle typically ranges from 2 to 5 years, achieving "one-time filling, continuous operation for many years." For small-scale decentralized water supply, situations requiring high water quality stability, or sites where chemical dosing is not feasible, it is an adsorbent choice that combines "worry-free, economical, and healthy" benefits!

Core advantages of BKsorb Granular Ferric Hydroxide Arsenic Removal Media:

Three Highs

• High Precision: BKsorb can stably reduce total arsenic to <0.01 mg/L (below detection limit) in a single filtration.

• High Selectivity: Targets only specific ions such as arsenic, vanadium, uranium, and phosphorus, with no adsorption of background ions like Ca²⁺, Mg²⁺, Cl⁻, SO4²⁻, keeping the mineral content of the effluent essentially unchanged.

• High Adsorption Capacity: Measured at 6–14 g As/kg media, approximately 5 times that of traditional activated alumina or resin.

Three Nones

• No Chemical Dosing: Pure physico-chemical adsorption, requiring no oxidants, coagulants, or acids/bases.

• No Leaching Risk: Substrate is iron hydroxide, NSF/ANSI 61 certified, releasing no harmful substances into water.

• No Arsenic Sludge: No floc formation, eliminating secondary pollution and hazardous waste dewatering costs.

Three Saves

• Saves Operating Costs: No daily electricity or chemical consumption; direct cost per ton of water (including media replacement amortization) ≈0.15–0.25 RMB, significantly lower than the combined cost of coagulation and sludge treatment.

• Saves Space: Empty bed contact time of 3–5 minutes, filtration rate up to 10–30 m/h, tank volume 50–80% smaller than traditional processes.

• Saves Labor: Maintenance-free for 1–5 years after installation, requiring only periodic backwashing or media replacement.

Three Eases

• Easy to Scale: Modular design, linearly scalable from 1 m³/d community supply to 100,000 m³/d large water plants.

• Easy to Manage: One-time media replacement when differential pressure or effluent arsenic concentration reaches set values, no complex adjustments needed.

• Easy to Install: Can be loaded into any pressure or gravity filter, compatible with existing sand filter tanks.
