olumnar activated carbon is a cylindrical granular adsorbent material. It is refined from high-quality raw materials such as coal, wood, or nut shells through multiple processes, including crushing, kneading, extrusion molding, carbonization, and activation. With a uniform structure and high mechanical strength, the particles are not easily broken, effectively reducing dust generation during use. The product features a rich porous structure and a large specific surface area, providing strong adsorption capabilities for various organic pollutants, heavy metal ions, and harmful gases. It also has excellent chemical and thermal stability, allowing it to be used for a long time in various complex environments. Thanks to its fast adsorption rate, large adsorption capacity, and recyclability, columnar activated carbon is widely applied in industrial wastewater treatment, drinking water purification, air purification, decolorization and purification in the sugar and wine industries, and as a catalyst carrier in chemical production. It is an essential functional material in both industrial and environmental protection fields.
