  The key force of water purification​ In the treatment of drinking water, powdered activated carbon can be called the "guardian" of water quality. Water sources often contain various odorous substances, organic matter and some heavy metal ions. These impurities not only affect the taste of water, but may also threaten human health. Powdered activated carbon can efficiently adsorb these harmful substances with its highly developed pore structure. When it is put into the raw water, it quickly mixes with water, and its huge specific surface area is like countless tiny "adsorption traps" to capture impurities in the water. Whether it is geosmin produced by algae or phenolic compounds brought by industrial emissions, it is difficult to escape the adsorption of powdered activated carbon, thus providing people with sweet, safe and reliable drinking water. ​ In the field of sewage treatment, powdered activated carbon also shows its prowess. Sewage has complex composition a...

Powdered activated carbon: small particles, big effect Among many materials, powdered activated carbon, although its particles are tiny, contains huge energy and shows extraordinary value in various industries. ​ Quality assurance in the food and beverage industry Powdered activated carbon plays a vital role in the production process of food and beverage. Taking the sugar industry as an example, the raw sugar liquid obtained after the initial processing of sugarcane or beets contains a variety of pigments, colloids and impurities, which will affect the color and taste of the sugar. Powdered activated carbon can accurately adsorb these impurities, making the sugar liquid clear and transparent, and after subsequent crystallization and other processes, it produces white and pure white sugar. In the beverage industry, whether it is fruit juice drinks, carbonated drinks or alcoholic drinks, powdered activated carbon can remove odors, pigments and microbial metabolites, etc., and improve the...
