60mm Polyster + PP Cord Bio Filter Media For Water 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).

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.
