Coal-based columnar activated carbon is the most commonly shaped activated carbon. Coal pellet activated carbon is mainly used for air purification. But for water treatment, it also has great advantages. Pellet activated carbon will greatly reduce the wear rate in water treatment, and no fine particles will appear during backwashing. The regular columnar activated carbon size is 4.0mm. And that's also can be adjusted based the water treatment circumstance.

Extruded activated carbon uses its own super adsorption to purify harmful substances in the water to achieve the purification of water treatment. Different grade coal columnar activated carbon can be used for tap water, wastewater, and drinking water treatment. The conventional activated carbon specification for drinking water filtration is 1.5mm,2.0mm. Coal columnar activated carbon can be applied to different water treatment scenarios: activated carbon filter tanks, fish tanks, and industrial water tanks..
