60mm Polyster + PP Cord Bio Filter Media For Water 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. Effectively remove various pollutants in water
2. Efficient microbial carrier for symbiosis of bacteria and algae
3. Accelerate the establishment of natural water ecosystem
4. Promote microbial diversity

Usage
1. Remove organic matter
A large number of microorganisms attach to the surface of ecological base, adsorb and oxidize organics, * eventually decompose organics or transform them into microbial components, so as to remove BOD in water body.
2. remove SS
The design of ecological water grass type can create a gentle water conservancy environment and accelerate the sedimentation of suspended solids; the collision of suspended solids in the ecological base causes its full sedimentation; the microbial flocculation on the surface of the ecological base causes the suspended solids to be adsorbed and finally fall to the bottom with the falling off of the biofilm.
3. Remove nitrogen and phosphorus
The A / O environment and microporous structure formed by the two-sided structure of ecological base create suitable conditions for the growth of nitrogen and phosphorus removal bacteria and algae. *Finally, it was removed by metabolism and mineralization of algae.
4. Control of suspended algae
More nutrients are transferred to the surface of ecological base by the super surface adsorption of ecological base, which makes phytoplankton in a disadvantageous position in the survival competition, resulting in its abnormal growth, reproduction and even extinction.
