Description 

 

Anthracite coal is a kind of filter used in water treatment. It is suitable for the treatment of common

acid, the middle degree alkali. This product has large surface area, and its various indexes all

exceed the Construction Department’s standard. Anthracite filter is especially selected from the

deep well minerals, so it includes the highest percentage of carbo. It must have been filtered and

washed to make sure it can be used for water filting. Since it has better granular maintaining ability,
