“Lanhua” brand anthracite is well known in the world, it is processed into filter media and applied in water treatment as a filter material ,because of its advantage of uniform particle size, less number of dropouts, more absorption quantity and it is regarded as the most ideal filter media for water treatment.

Based on scientific management and advanced production and inspection equipment, our products meet not only the requirements of CJ/T 43-2005 (national standard in our country), but also the requirements of JWWA-A-103(Japan)、 AWWA-B100（America)

Anthracite filter media is made of top quality anthracite, anthracite is called as normally stone coal, white coal.Its degree of coalification is the highest in the coal, it is black and solid  with metal luster,it is mainly used as fuels and raw materials.After anthracite is processed into anthracite filter material and applied in water treatment as a filtering material, its characteristics are as follows:

1.Uses: to purify and filter waste water

2.Scope of application: potable water, industrial water, purification and filtration for industrial waste water.

3. Feature: anthracite filter media is used for filtration of purification water, acid and base, oil separator and sewage treatment. It has more advantages than any other filter media:

 (1) it is steady for acid and base

 (2) faster filtering speed, stronger electric property than sand, with electric absorption effect,high rate filtration.

(3) high removal rate, anthracite filter media has wide absorption area and removes more pollutants, removal rate approximately can reach 99%.

(4) long life,  large water treatment quantity

(5) To promote the seperation of turbidity and bacteria

(6) excellent solidification stability and reducing scale

(7) low specific gravity and  reducing bearing thickness

(8)specific gravity is about 1/2 of sand，to use less water while backwashing

4.Apperance: granular shape

5.Princilple: after subparticle suspended solid flocculates with the drug added and then removed by anthracite filter media.

6.Common specification.
