200mm Polyester + PP Composite Packing For Waste Water Treatment
Product Description
Composite packing is another kind of packing improved on the basis
of soft packing, which is composed of fiber bundle, plastic ring
piece, casing pipe and intermediate rope. Under the support of
intermediate plastic ring piece, fiber bundle avoids the phenomenon
of middle agglomeration of fiber bundle, at the same time, it can
play a good role in water distribution and air distribution, has
good contact and mass transfer conditions, and has high utilization
rate of oxygen. It is suitable for various sewage and wastewater
treatment projects In contact with oxidation wall, oxidation tank,
oxidation tank and other equipment, the advantages of soft and semi
soft packing are overcome, which are ideal products in the
biochemical treatment of sewage. Parameters and specifications of
combined packing: diameter: φ 150 mm, φ 180 mm, φ 200 mm, spacing:
80 mm, 100 mm.
Product Features
1. It has a plastic ring as the skeleton, loaded with vinylon wire,
which is fastened on the plastic ring. In the sewage, the tow is
evenly distributed, easy to form and change the membrane, and has
good adaptability to the sewage thick liquid.
2. The structure is to change the plastic disc buckle into a double
circle big plastic ring, and press the aldehyde fiber or polyester
fiber on the ring to make the fiber bundle evenly distributed.
3. The inner ring is a snowflake shaped plastic branch, which can
not only hang film, but also effectively cut bubbles, improve the
transfer rate and utilization rate of oxygen, make the water gas
biofilm have full exchange, and make the organic matter in the
water have efficient treatment. The combination packing is the best
choice under the condition of strong aeration turbulence.
4. Application of combined packing: it is used in sewage and
wastewater treatment engineering, matched with equipment such as
contact oxidation tower and oxidation tank of oxidation pool, and
is a kind of biological carrier for wastewater treatment by
biological contact oxidation and anaerobic fermentation.
5. Performance characteristics of combined packing: it has high
heat dissipation performance, small resistance, good water and air
distribution performance, easy to generate film, change film, good
applicability to sewage concentration, and has the effect of
cutting bubbles.

Application
The composite packing is used in sewage and wastewater treatment
engineering, matched with contact oxidation tower, oxidation tank
and other equipment. It is a kind of biological carrier for the
treatment of wastewater by biological contact oxidation and
anaerobic fermentation.
It is widely used in printing and dyeing, silk spinning, food,
pharmaceutical, petrochemical, papermaking and other wastewater
treatment, so it is welcomed by the majority of users.
Installation
There are square, equilateral triangle and other installation
methods. The frame has steel structure and soft rope structure,
which are made into upper and lower layers respectively. The
distance between the two layers is the effective length of the
filler. The two ends of each piece of packing
are provided with ropes for binding. During installation, special
knotting method is used to fix the packing on the upper and lower
frames.
