carbon powder is a fine, dry granule of pressed activated carbon. It is manufactured in a variety of shapes and sizes. These include rods, ingots, pieces, pellets, discs and granules.
Activated Carbon is a very versatile material. It can be used in a wide range of applications, including air purification, capacitive deionization, supercapacitive swing adsorption, solvent recovery, gas storage, sewage treatment and medicine.
It can be derived from a variety of sources, such as coconut husks or paper mill wastes. Activated carbon is often used in the production of hydrogen and methane.
During an activation process, the carbon is treated to remove oxygen and other impurities. This process can be carried out with a variety of materials, and it usually occurs in special ovens at high temperatures.
The adsorption of organics from waste water is typically achieved through the use of powdered activated carbon (PAC). This product can be manufactured in a variety of pore sizes and mesh sizes depending on application requirements, and it has been shown to reduce organic levels by up to 90%.
PAC particles are sized to provide a large surface-to-volume ratio and small diffusion distance, which improves adsorption performance. Typically PAC is manufactured as a particulate form, and the average diameter of its particles is between 0.15 and 0.25 mm. This is the largest mesh size available for a wide variety of waste water treatment applications. Using an activated carbon with a larger mesh size provides less pressure drop during the filtration process, and lower temperatures can increase the pressure drop.
