Product Introduction

Granular Activated Carbon (GAC) is a high-performance porous adsorption material widely used in water treatment and waste gas purification fields. It is refined from high-quality coal and biomass raw materials through multi-processes such as high-temperature carbonization, deep steam activation, and precise particle screening. The product has a dense particle structure, abundant pores, a large specific surface area, stable adsorption capacity, high mechanical strength, and low ash content. Compared with powdered activated carbon, it has better permeability, a longer service life, and can be recycled and reused. Its physical and chemical properties are stable, acid and alkali resistant, and heat resistant, widely used in water quality purification and waste gas treatment, and is a commonly used multifunctional adsorption material in municipal and industrial environmental protection projects.

2. Product Material

4. Product Advantages and Features

・Strong adsorption capacity: Equipped with a composite pore structure of micropores and mesopores, it efficiently adsorbs organic matter, residual chlorine, odors, turbidity substances in water, and VOC pollutants in waste gas, with outstanding purification effects.
High hardness and resistance to powdering: particles are dense and wear-resistant, less prone to cracking under continuous washing by water or air flow, reducing secondary pollution from powder and ensuring stable system operation.
Stable physical and chemical properties: acid and alkali resistance, high temperature resistance, corrosion resistance, stable performance in complex water and flue gas conditions, wide application range.
Supports regeneration and offers excellent cost-performance: Filter media can be recycled and reused, significantly reducing the long-term cost of replacing consumables in engineering projects.
Excellent permeability: uniform particle size distribution, smooth water and vapor flow, reducing equipment resistance, and enhancing the overall filtration system's operating efficiency.

5. Core Functions

Organic Pollutant Adsorption: Retain and adsorb organic impurities, pigments, and odor molecules in water bodies and waste gases.
・Dechlorination and odor removal: Eliminate residual chlorine in water, odor from water bodies and exhaust gases, and improve the sensory indicators of the medium.
Waterbody Depth Purification: Reduces COD, removes trace impurities, and improves effluent water quality as a deep filtration unit.
・VOC Emission Treatment: Adsorbs industrial volatile organic compounds to achieve waste gas purification.
・Pre-filter protection: Intercepts trace suspended particles, protects subsequent precision filter materials, and extends the service life of the entire filter system.
Solvent Recovery: Adsorption for industrial organic gases to achieve solvent recovery and reuse.
