In modern hospital cleanroom management systems, operating room air quality directly impacts patient post-operative recovery, infection risk, and the health of medical staff. Besides traditionally concerning particulate matter, bacteria, and viruses, volatile organic compounds (VOCs), residual anesthetic gases, disinfectant fumes, and rubber and plastic odors are also significant factors affecting the operating room environment. To achieve higher standards of air purification, acid-washed high quality coconut shell activated carbon has become an increasingly recognized solution in the industry.

Yellow phosphorus production often involves various impurities, such as arsenic, sulfur, silicon, iron, and organic impurities, which can affect the quality of subsequent products and the stability of equipment operation. Therefore, incorporating efficient purification methods into the yellow phosphorus refining process is essential. Activated carbon, due to its excellent adsorption properties, is widely used for decolorizing, removing impurities, and deodorizing yellow phosphorus.

Spray booths are essential facilities in automotive, furniture, aerospace, and industrial coating operations. While they provide controlled environments for painting and coating applications, they also generate significant amounts of volatile organic compounds (VOCs), overspray particles, and hazardous air pollutants. Activated carbon filtration has become a regular method for VOC removal of spray booths. And pellet & honeycomb activated carbon is prefered choosen.

Biogas produced from anaerobic digestion contains not only valuable methane (CH₄) and carbon dioxide (CO₂), but also numerous impurities that must be removed before the gas can be used as fuel or upgraded to biomethane for grid injection. Among these contaminants, volatile organic compounds (VOCs) and hydrogen sulfide (H₂S) present the most significant challenges for biomethane production facilities.
