Powdered Activated Carbon (PAC):
Powdered activated carbon has a larger contact surface area, making it particularly effective for emergency treatment and pretreatment of mildly contaminated water.
It offers advantages such as fast filtration speed, strong adsorption capacity, excellent decolorization and deodorization capabilities, as well as cost-effectiveness and durability.

Granular Activated Carbon (GAC):
Granular activated carbon is primarily used for advanced treatment to remove trace toxic and harmful substances.
