Specifications

1. Appropriate density, high mechanical strength, good biological and chemical stability;
2. Large specific surface,

1   The product introduction:

 

Shale is characterized by bio-ceramic filter material light, porous developed 

large specific surface area, 

adsorption ability, compression wear, head flush intensity is low, the ability 

Sewage Interception is good. It applies to acid, neutral water, the alkaline water 

treatment, it is an ideal water treatment products.

4.Advantage:

1. Appropriate density, high mechanical strength, good biological and chemical 

stability;

2. Large specific surface, strong pollutant entrapment, easy-clinging high-efficient biology film.

3. Lower loss of the pressure head, longer filtration cycle, smaller water 

consumption of reverse washing.

4. Unaffected by flow rate or pollution loading variations, low temperature 

resistance and quick start-up.
