PE08 100% Virgin HDPE Filter Media For Wastewater Treatment In
White
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.
Characteristics
1. It is better to use high-quality copolymers than other materials
such as PVC, because they will not degrade in waste water for a
long time and will not be toxic to microorganisms.
2. Special structure, the hollow packing structure has three layers
of hollow circles inside and outside, each circle has one edge
inside and 36 edges outside. It has been successfully researched
and developed for many times and adopts one-time forming.
3. With high specific surface area, the specific surface area of
ordinary microorganism is 90-180, the specific surface area of
hollow filler can reach 600, and the double specific area can reach
more than 860. Because of the high specific surface area, the
biomass in unit volume is high, and the purpose of short hydraulic
retention time can be achieved.
4. High activity of microorganisms. The biofilm growing on the
surface of the packing is due to the fluidization collision of the
packing. Aeration scour makes the microorganism in the logarithmic
growth period with high activity and high treatment efficiency.
5. Hollow packing is floating type, easy to replace and long
service life.
6. The ability of denitrification and decomposition of organic
matter is strong, so as to remove ammonia nitrogen. Specification
and model of fluid bed packing: type, model and specification: φ
25mm, length: 10-12mm, thickness: 0.6-0.8mm, middle circle:
0.4-0.5mm, outer circumference: toothed, center to outer circle:
three layers.
