Taking refined clay as main raw material and mixing with appropriate modification agent.

Ceramsite filter material

1.Key Feature:

a.With developed Surface pore and specific surface area,can handle water with high quality.

b.Take the advantage of regular shape, density moderate, easy to back flush, low energy consumption, back flush do not lose material.

c.With void distribution uniform of precoat.

d.it will not release any material to water to produce secondary pollution even soak for a long time.
