What are the absorptive properties of powder activated carbon primarily used for?

The absorptive properties of powder activated carbon are primarily utilized for the removal of taste and odor-causing substances. This effectiveness arises from the large surface area and porous structure of activated carbon, which allow it to adsorb organic compounds responsible for unpleasant tastes and odors in water. When water passes through a bed of powder activated carbon, these problematic substances adhere to the surface, thereby improving the overall sensory quality of the water. While activated carbon can also play a role in reducing color and certain nutrients, its primary application in drinking water treatment is linked to enhancing palatability and aesthetic qualities.
