Product Description

Spiral Cord Braided rope filler is made of PP+alcoholized fibers as raw materials, using a mixed weaving method of elastic and soft materials. The threading adopts a snake like pattern, forming countless circular fibers to form a radial structure, increasing its surface area and suitable for the growth and reproduction of various microorganisms, so that the concentration of attached microorganisms can reach over 15000mg/l; The circumferential radial structure formed by elastic and soft materials increases the porosity of the filler, enabling good transmission of solid, liquid, and gas phases; The unique circular structure can effectively prevent excessive peeling of biofilm caused by water flow impact.

Advantages & Features

1.The amount of film hanging can reach 15-20g/L, which is 5-6 times higher than traditional fillers and has a higher organic load.

2.Compared with the traditional Activated sludge, the sludge reduction is more than 40%.

3.Synchronous nitrification and denitrification have good effects, strong denitrification ability, and a nitrogen removal rate of 80-90%.

4.Has lipophilic, hydrophilic, strong adsorption ability, fast film formation, and easy film removal.

5.Lightweight, low operating costs, long service life, convenient installation and maintenance and easy to use with other equipment.

Working Principle

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).

Installation method

1.The vertical and horizontal spacing b (100~200mm) is set for the packing support, so the installation amount of 1m3 packing support rope type biological filler is 25~100m.
2. The rope type biological filler is fixed directly on the filler bracket with PP and PE ties. The rope type biological filler does not need to be cut, but can be attached 100~200mm along the bracket and then fixed.
3.There are two ways to set rope type biological filler in the aeration tank: split flow type, the filler is installed on one side and the other side is used for aeration. Sufficient water flow space must be reserved above and below the filler, and aeration deflector can be set when necessary; The second type is the direct type. The aeration device is directly installed under the filler and the water air mixed flow directly contacts with the biofilm and supplies oxygen.
4.Split installation spacing b: 100~150mm; Direct installation spacing b: 150~200mm.
