Columnar activated carbon is cylindrical in appearance, mostly dark gray or grayish-black in color, and emits no heat or toxins. It is made from high-quality wood chips, coconut shells, and other similar raw materials.

Columnar activated carbon is cylindrical in appearance, mostly dark gray or grayish-black in color, and is non-toxic and odorless. It is produced using high-quality wood chips, coconut shells, and other raw materials, through continuous crushing, stirring, pressure filtration, molding, drying, and carbonization to obtain the commonly used columnar activated carbon. Due to the use of high-quality raw materials, the resulting columnar activated carbon has lower ash content and fewer impurities than ordinary coal-fired activated carbon, achieving superior CTC and adsorption values. Each product has a very fine particle diameter, allowing for large adsorption and even desorption of the adsorbent, thus extending its service life. Ordinary medium-based activated carbon has an average lifespan of just over one year, while this columnar activated carbon can last two to three years. This wood-based columnar activated carbon is a non-binding activated carbon, significantly changing the traditional method of binding with tar. It does not require any binders, relying entirely on the interrelationships and inherent properties of carbon molecules through scientific methods. This also avoids carbon pore clogging, allowing for full utilization of the carbon pore's adsorption capacity.

Application industries: Chemical, pharmaceutical, environmental protection, food, metallurgy, steel, electroplating solutions, industrial exhaust gas purification and treatment, etc.

Common specifications for columnar activated carbon: 1.0 mm, 1.5 mm, 3.0 mm, 4.0 mm, 5.0 mm, 6.0 mm, 80 mm, etc. Custom sizes are available to meet specific customer needs.

1. Utilizes advanced production technology, resulting in a service life 3-4 times longer than coal-based activated carbon.

2. Extensively high adsorption and desorption capacity, thereby improving solvent recovery rates.

3. Effectively deodorizes and removes COD, BOD, pigments, odors, and other toxic and harmful substances from water. Adding a filter further optimizes air purification performance.

4. Offers high cost-effectiveness and allows for the recycling of organic matter in various settings.

5. Has a high ignition point, making it relatively safe to use.

Columnar activated carbon can be used directly or placed in a purification cabinet or adsorption bed. If the waste gas concentration is still high and the discharge volume is large, a purification cabinet or adsorption bed can be added for continuous colloidal application. During use, if the waste gas temperature is too high, the adsorption capacity will decrease. There is an inverse relationship between adsorption capacity and temperature; the faster the temperature rises, the faster the adsorption capacity decreases, and vice versa. Another situation to note is to avoid high concentrations, oil mists, and high dust content, as these will greatly increase resistance and reduce the adsorption effect. If this occurs, it is best to install a dust filter before use to achieve the best purification effect and extend the service life.
