Specification :

Fine Pored Biofiltration Material is made from high quality clay. It can improve filtration efficiency, reduce cost and has good efficiency in reducing nitrogen, ammonia, phosphor to 99%. It is already substitue of quartz sands and anthracite. Filtration material can be used in waste water secondary treatment through Bio-chemical process, as biology carrier.
Features:
- Appropriate density, high mechanical strength, god biological and chemical stability
- Large surface area, strong pollutant entrapment, easy-clinging high-efficient biology film.
- Lower loss of the pressure head, longer filtration cycle, smaller water consumption of reverse washing.
- Unaffected by flow rate or pollution loading variations, low temperature resistance and quick start-up.
