Coal-based column activated carbon with high quality anthracite as raw material. Coal-based column activated carbon has a good adsorption effect for the volatile organic compounds in water, which can make removal rate of adsorption reach 25%~65% for all kinds of volatile organic compounds in water.
Its appearance is black columnar, the characters are tasteless, non-toxic, high mechanical strength, developed pore structure, large surface area, the pore size is between coconut shell activated carbon and wood activated carbon, high adsorption speed, high adsorption capacity, easy regeneration. It is a kind of durable environmental protection activated carbon.By strict material selection and rigorous process, adopting the advanced technology and high temperature activation made. Comparing to different molecular weight organics can be seen that for volatile organic compounds, the higher the molecular weight, the higher the removal rate of the adsorption. This rule is similar to phenol and cationic that for the small molecule organic matters in water, the higher the molecular weight, the more easily adsorbed by activated carbon.
