Features of Biological Lace
01
A large number of microorganisms can be fixed to form an ideal environment where they coexist. High treatment effect can be achieved through one-level treatment, which has been proved in many river ecological restoration cases.
02
The radial structure is composed of numerous circular fibers, which can increase the surface area and adapt to the growth and reproduction of various microorganisms, so that the concentration of attached microorganisms can reach more than 150,000mg/L, which is used in the treatment of high concentration ammonia nitrogen wastewater of a large electronic company.
03
On its surface, ammonia nitrogen can be reduced by the proliferation of aerobic microorganisms, and biological denitrification can be carried out by the proliferation of anaerobic microorganisms inside the biological lace.
04
The shape is rope shape, so the shape can be changed freely during setting. Biological lace is ring-shaped, which can avoid excessive peeling of biological film due to water impact.
05
Shaking in the wastewater can not only absorb the dissolved oxygen in the water, but also improve the contact efficiency with the water and the removal rate of organic matters.
06
Not only in the treatment of low concentration wastewater, but also in the high concentration reaction tank which is easy to be blocked by contact materials.
07
It can attach a large number of microorganisms, so it can also be used in a small-scale reaction tank.
How to Install
The vertical and horizontal spacing of packing support is 100-200mm.
The braided packing is fixed by PE / PP tie directly on the packing bracket. The braided packing does not need to be cut, but can be attached 100-200mm along the bracket and fixed again.
There are two ways for the biological rope to be set in the aeration tank: the first is the split flow type, the packing is installed on one side, and the other is aeration; the second is the direct type, the aeration device is directly installed under the biological rope packing, and the water and air are mixed.
The installation spacing of split type is 100-150 mm, and that of direct type is 150-200 mm.
Frequently Asked Questions
How does biological lace achieve simultaneous nitrification and denitrification?
Ammonia nitrogen is reduced on the surface of the biological lace by the proliferation of aerobic microorganisms, while biological denitrification takes place inside the biological lace through the growth of anaerobic microorganisms.
What is the advantage of the radial structure in biological lace?
The radial structure consists of numerous circular fibers that greatly increase the surface area. This allows the concentration of attached microorganisms to reach over 150,000 mg/L, making it highly effective for high-concentration ammonia nitrogen wastewater.
Does the biological film peel off easily due to water impact?
No. The biological lace is designed in a ring shape, which helps prevent excessive peeling of the biological film caused by the impact of water flow.
What is the recommended spacing for the packing support during installation?
The recommended vertical and horizontal spacing for the packing support is between 100 mm and 200 mm.
What are the two ways to install biological rope in an aeration tank?
The two methods are: 1) Split flow type, where the packing is installed on one side and aeration is on the other; and 2) Direct type, where the aeration device is installed directly beneath the biological rope packing to mix water and air.
What is the installation spacing for split flow versus direct type systems?
For the split flow type system, the installation spacing should be 100-150 mm. For the direct type system, the spacing should be 150-200 mm.
