BIO FILTER

The waste water go through the suspending media of MBBR reactor, form the biological membrane on the surface of the media gradually, with the action of the microbial on the biological membrane, the waste water is purified. The Bio filter media can move freely in the reactor with the mixing of the water; For the aerobic reactor, the aeration will make the media move; For the anaerobic reactor, mechanic mixing will make the media move. Our MBBR media is new-developed media for the MBBR process, has better treatment effect compare to traditional media.

MBBR midia can be also made by customoer' s special request. Bio filter media Applications: 1. Very good effluent quality ( 20BOD/ 30SS/ ammonia) . 2. Low capital cost. 3. Simple, robust design. 4. Energy efficient. 5. Ease of installation and operation. 6. Capacity of existing works can be quickly and easily increased. 7. Low operating cost. 8. Small footprint for new works. 9. Upgrade of existing works-simultaneously increase capacity and improve effluent quality.
