How ZONE’s Arsenic Removal Filter Media Eliminates Arsenic in Drinking Water – Efficiently, Safely, and Sustainably

Update time: 25-09-19 Views: 6

Arsenic in groundwater is a silent threat. Odorless, colorless, and tasteless, it seeps into wells and aquifers, exposing millions to serious health risks. At ZONE, we’ve developed a high-performance arsenic removal filter media that not only removes arsenic below WHO standards, but also requires no backwash, produces no sludge, and lasts for years.

Why Arsenic Is a Global Concern

According to the World Health Organization (WHO), arsenic is a Group 1 carcinogen. Long-term exposure to arsenic levels above 0.01 mg/L can lead to:

- Skin lesions

- Cardiovascular disease

- Cancers of the bladder, lung, and skin

Regions such as Shanxi, Inner Mongolia, and Xinjiang in China are known high-arsenic zones. Globally, over 70 countries face similar challenges. Traditional treatment methods like coagulation and ion exchange are often costly, complex, and generate hazardous waste.

ZONE Arsenic Removal Filter Media

Our arsenic removal filter media is a nano-engineered adsorbent with a surface area of 300 m²/g, offering exceptional performance in both household and industrial applications.

✅ Key Features:

- Dual-valence adsorption: Effectively removes As(III) and As(V) without pre-oxidation

- High capacity: Distribution coefficient (Kd) = 18,000 mL/g, 20× higher than conventional media

- Zero sludge: Arsenic is stabilized as FeAsO₄·2H₂O, passing TCLP leaching tests

- Smart replacement alert: Effluent pH rises by 0.3–0.5 units when media is exhausted

- Long lifespan: 1–5 years depending on water quality

- No backwashing required
