Tube Bioreactor
As a biocarrier in bio waste water treatment plant, fixed bed biological filter has been widely used in small sewage treatment projects over the world. Material for the bio sewage treatment plant is the modified HDPE, a high quality plastic in polyolefins with corrosion resistant, high temperature resistant, aging resistant, and adding uv resistance, oxidation resistance, water and other additives to improve the performance during bio sewage treatment plant, after the special processing, it is tailored for sewage treatment, the service life can reach more than 20 years. Fast filming speed, large amount of film carring, stable operation, strong impact resistance capacity. Complete mixing of air and water, three-dimensional flow, excellent treatment effect; Stable structure, flexible combination, suitable for various areas.
The fixed-bed technology
As biological treatment process, the fixed-bed technology is based on different microorganisms, which naturally occur in domestic wastewater. Contrary to sludge-based processes, these organisms don`t need to be kept in suspension as activated sludge in the reactor, but have a fixed surface to grow on, the so called fixed-bed.
Due to their special structure, the fixed-bed elements have a high specific surface for increased contact between the biofilm and the wastewater. The air for the aerobic processes is brought in from the outside by a side channel compressor. Underneath the fixed-bed the air is dispersed evenly in small bubbles by membrane diffusors. The specific arrangement of the aerators causes a vertically circulation flow, which guarantees a homogeneous mixing in the reactor.
- Open structure - Danmotech applied filter media has open structure which will not clog and is easy to clean.
- Consistent high performance – Danmotech applied media performs consistent which guaranty the promised treatment effect
- Strong – Danmotech applied filter media will not settle, not even with time. Bio-media is strong enough to carry the weight of a person
- Light – Danmotech applied filter media can if necessary easy be lifted our of treatment system for cleaning
