100% Virgin HDPE MBBR Filter Media k2 Mbbr Carrier In The
Aquaculture
Product Description
Fluidized bed packing, also known as MBBR packing, is a new type of
bioactive carrier. It adopts scientific formula, according to
different water quality requirements, integrates different kinds of
Microelements in polymer materials, which are conducive to the
rapid growth of microorganisms. After special process modification
and construction, it has the advantages of large specific surface
area, good hydrophilicity, good fluidity, high biological activity,
easy to hang membrane, good treatment effect, long service life and
so on.
Principle of action of fluidized bed packing when sewage passes
through the fluidized bed packing reactor, microorganisms in the
water continuously adhere to and grow on the inner and outer
surfaces of the fluidized bed packing to form a biofilm. The fluid
bed packing rotates freely under the agitation of the mixed liquid
in the reactor. The biofilm fully contacts and decomposes the
pollutants in the water body, so that the water quality can be
purified. The turnover of mixed liquid and the movement of carrier
are realized by aerobic aeration or anaerobic agitation.

Application
1. The fluidized bed biofilm reactor can be used to remove organic
matters and nitrogen. The flow bed biofilm reactor process can be
used to remove conventional pollutants, even nitrogen and other
nutrients in wastewater.
2.It is suitable for the transformation of the traditional
activated sludge method.
3. Applied to filtration of fish pond or high-purity Aquarium
Film maturity discriminant editing
Visual judgment:
The biofilm is evenly distributed on the surface of the carrier,
the closer it is to the surface of the carrier, the denser it is,
on the contrary, the looser it is, and the color of the carrier
becomes darker, which indicates that the carrier film has entered
the mature stage.
Microscopic judgment:
The structure of biofilm is compact, the species of microorganism
are diverse, the number of fixed ciliates, Campanula and
Dendrolimus are mostly, a small number of rotifers and swimming
ciliates show the maturity of biofilm.
