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.
