Activated Carbon | Pureflow
Granular activated carbon is the media of choice for fixed bed water treatment systems, as it exhibits the best mix of surface area (e.g., particle size) and pressure drop. Extruded activated carbon combines powdered activated carbon with a binder, which are fused together and extruded into a fixed shape activated carbon block.
