Composite packing is used in wastewater and wastewater treatment engineering projects, with supporting facilities such as contact oxidation towers, air oxidation tanks, and air oxidation tanks. It is a microbial particle carrier for solving sewage problems using microbial contact air oxidation and continuous fermentation methods. So, how do we know the quality of it?
Composite fillers are widely used in printing and dyeing factories, silk and wool textiles, food, pharmaceuticals, petrochemical equipment, paper industry, cyanide containing wastewater treatment, and are warmly welcomed by many customers.
Composite fillers have high heat pipe heat dissipation characteristics, low friction resistance, good water distribution and aeration characteristics, easy membrane acquisition and replacement, and good universality for wastewater concentration values. They also have laser cutting bubble effect.
In aerobic and anaerobic tanks, composite packing or three-dimensionalelastic multi-faceted hollow sphere packing is often used. Generally, the actual effect of composite packing is stronger and more suitable for shaping Escherichia coli. Therefore, a large amount of composite packing is used in situations where sewage treatment standards are higher. In the end, the prices of these products vary from manufacturer to manufacturer. You get what you pay for. What are the drawbacks of cost-effective fillers?
When people look at the structure of composite fillers, it can be visualized as a plastic rope strung around circular pieces, with chemical fibers tied on top. When applied, it is immediately tied to the building steel bars of the air oxidation tank, making installation very convenient. The key concentration of product cost for manufacturers of multi-faceted hollow ball fillers that facilitate practical operation lies in the discs and the chemical fiber filaments adhered to them. Knowing this makes it easy to distinguish quality. In general applications, we measure the amount of each piece every ten centimeters. For example, for a length of one meter, it requires 11 pieces, which is like a row of rural bungalows built in the countryside, with several houses, requiring an additional "leg".
Some companies will loosen the 10cm spacing in order to reduce costs. It is obvious that if the spacing is doubled, the number of pieces used will be reduced by half, and money will be saved in this way. Some people have also noticed that some multi-faceted hollow ball filling companies add fewer chemical fiber filaments. This thread is very expensive, costing tens of yuan per kilogram. Although it may not fit much on one piece, over time, it has a cumulative effect and is also a way to control costs.
Therefore, the lower the number of pieces, the lower the chemical fiber yarn, and of course, the lower the price. Moreover, there is no way to save raw materials anymore.
Composite packing is a development trend based on flexible packing and semi flexible packing, which combines the advantages of both. Its structure is to replace the plastic disc buckle with a double ring large plastic ring, and press aldehyde chemical fibers or polyester fibers on the ring of the ring to evenly distribute the fiber bundles; The inner hole is a small snowflake shaped plastic branch, which can not only hang film, but also reasonably laser cut bubbles, improving the migration speed and utilization rate of oxygen. Provide sufficient exchange of extracellular matrix for water vapor, and efficiently solve the problem of organic compounds in water.
