Polyster PP Cord Bio Filter Media For River Pond Biofiltration Wastewater Treatment
Cord Bio Filter Media is a man-made bio-reactor, Using for drain off management using microbe activity to prevent water pollution in oceans, rivers, lakes, and marshes. In appearance, Bio Film Type Cord is a simple cord covered with countless rings of thread, made of polymers such as polypropylene, vinylon, polyvinylidene-chloride, binylon or nylon-polyester . Its unique properties thus provide a symbiotic culture bed for a wide spectrum of microbes.
When Bio Film Type Cord is manufactured, it leaves the factory with a slightly positive charge. Placed in water, it attracts microbes, which by nature have a slightly negative charge. The structure of the Bio Film Type Cord also attracts the microbes. Because of this, Bio Film Type Cord is the choice media for microorganisms to live and grow on. The microbes adhere to the threads and perform biodegradation. This is done in a three-step process including an anaerobic step for optimum solids removal (instantaneous breakdown).
1. Large amount of film hanging, up to 15-20g / L.
2. Compact structure, good supporting function, not easy to deform.
3. It has strong resistance to water impact and high packing strength.
4. It is suitable for high concentration ammonia nitrogen and total nitrogen wastewater.
5. High micro organism adhesion surface area, strong surface adsorption
6. Bionic water grass shape design, special weaving technology
| Diameter | Spacing | Row spacing | Surface area(m²/m³) | Porosity (%) | Finished weight(kg/m³) | Hanging film weight(kg/m³) | Load(COD.kg/m³.d) |
| 60mm | 150mm | 150mm | 6500-7000 | >99 | 1.0 | 300-450 | 6-8 |
| 20-40mm | 50-100mm | 100-200mm | 3200-6100 | >99 | 0.5-2 | 100-200 | 4-6 |
Application
It is widely used in new construction and renovation projects, and in wastewater from chemical industry, printing and dyeing, papermaking, food, domestic sewage and other industries. It is also applicable to the treatment of micro polluted water sources with BOD less than 300, such as river course treatment, landscape water area and initial rainwater. Traditional composite fillers can be replaced in the field of application.
