Product Description
Activated alumina arsenic removal agent is a porous adsorbent material prepared based on high-purity alumina. It features a large specific surface area, strong adsorption capacity, and stable operation, effectively removing arsenic (As³⁺ / As⁵⁺) from water. It is widely used in drinking water purification, groundwater arsenic removal, industrial wastewater treatment, and environmental engineering.
Zibo Xiangrun Environmental Engineering Co., Ltd., as a professional manufacturer of activated alumina, can provide stable and customizable arsenic removal solutions tailored to different water quality conditions and system requirements. We help customers achieve long-term, stable reductions in arsenic content to meet relevant water quality standards.
Adsorption mechanism of arsenic
In water treatment, water flows through an adsorption bed filled with activated alumina arsenic removal agent. Arsenic ions are adsorbed and fixed by the hydroxyl structures on the alumina surface.
For arsenic in the As(III) form, a pre-oxidation process can typically convert it into the more readily adsorbable As(V), thereby improving the overall arsenic removal efficiency.
Product Features
1. Highly Efficient Arsenic Removal Capacity
This product features a well-developed pore structure and abundant surface active sites, exhibiting excellent adsorption selectivity for arsenic in water, particularly showing superior removal efficiency for As(V) form. Under suitable pH conditions, it can significantly reduce the arsenic concentration in effluent, making it suitable for continuously operating water treatment systems.
2. High Mechanical Strength and Stable Operation
Utilizing a high-strength granular structure design, it boasts high compressive strength, low wear rate, and is not prone to pulverization. It can operate long-term in fixed-bed or filter column systems, reducing replacement frequency and lowering overall operating costs.
3. Wide Range of Applicable Water Quality
Activated alumina arsenic removal agent can be used in various water treatment scenarios.
4. Recyclable and Economical
Under reasonable operating conditions, activated alumina arsenic adsorbent can extend its service life through regeneration, helping to reduce consumable costs and solid waste generation, meeting environmental protection and sustainable development requirements.

FAQ
Q1: Which type of arsenic is activated alumina primarily suitable for removal?
A: It is more effective at adsorbing As(V). If As(III) is the predominant arsenic in the water, it is recommended to use it in conjunction with an oxidation pretreatment process.
Q2: How often does the product need to be replaced?
A: The replacement cycle depends on the influent arsenic concentration, operating conditions, and system design. A specific assessment based on project data is required.
Q3: Can it remove other pollutants simultaneously?
A: Arsenic removal is its primary function. It also has a certain synergistic removal capability for some heavy metals or impurities, which needs to be confirmed based on water quality analysis.
Q4:What pH conditions are suitable for activated alumina arsenic removal agents?
A:The product performs well in the pH range of 5-8 and is more suitable for neutral to slightly acidic water treatment conditions.
