Powdered activated carbons developed following the standardized procedure of direct activation,
are specifically developed for the elimination of a broad range of organic contaminants from potable, waste and process waters.
Particle size of powdered activated carbon (PAC) is comparatively smaller in contrast to granular activated carbons and therefore, presents a large surface to volume ratio.
PAC is used very rarely in the procedures as a committed adsorber vessel, keeping in mind the high head loss that would occur. More commonly PAC is are added straightaway to the process units,
like raw water intakes, rapid mix basins, clarifiers, and gravity filters.
Applications for powdered activated carbon include:
- Taste and odor reduction
- Removal of organic contaminants from fluid stream
- Disinfection-by-product (DBP) removal
- Dechlorination and chloramine reduction
- Pesticide removal systems
- Drinking water treatment
- Drinking water treatment
- Groundwater purification
- Wastewater treatment plants
