Polyster PP Cord Bio Filter Media For River Pond Biofiltration
Wastewater Treatment
Product Description
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).
Product Features
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
Technology Parameter
| 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.
