Product Introduction

Granular Activated Carbon (GAC) is a high-performance porous adsorption filter material widely used in water treatment and waste gas purification. It is refined from high-quality coal and biomass raw materials through multiple 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 for reuse. It has stable physical and chemical properties, is resistant to acid and alkali, and can withstand high temperatures, making it a multifunctional adsorption material commonly used in municipal and industrial environmental protection projects for water purification and waste gas treatment.

2. Product Material

Select high-quality coal/biomass raw materials with minimal impurities; constructed with developed microporous and mesoporous structures through high-temperature activation process. Products are divided into quality grades based on iodine value, ranging from 800mg/g to 1300mg+ with multiple specifications available, featuring high strength, controllable ash content, low dust emission, and meeting relevant standards for municipal water supply and industrial environmental protection.
