Printing and dyeing is a processing step in the textile industry, printing and dyeing in ancient China has a certain prototype, the traditional printing and dyeing technology is the embodiment of China’s traditional culture. With the continuous improvement of our living conditions, textile printing and dyeing products in our life demand is also increasing, it also makes the printing and dyeing industry constantly technology update, more and more large, but in the process of printing and dyeing will produce a lot of wastewater, if not treated directly discharge the sewage will be serious pollution to the surrounding environment. Today, we will come together to understand the role of polyacrylamide in the treatment process of printing and dyeing sewage:

Polyacrylamide for printing and dyeing sewage treatment:

We all know that the printing and dyeing industry water consumption is very big, according to statistics every processing a ton of textiles will use nearly one hundred tons of water, and the wastewater is very large, if direct discharge is not only environmental pollution is the waste of water resources, so printing and dyeing sewage treatment is not only related to environmental pollution problems, if properly treated make sewage can recycle that can save the cost of water in the process of printing and dyeing. Printing and dyeing sewage wastewater contains a large number of fiber impurities, dyes and chemical drug residues, and the large water quantity and water quality change is also large, is a more difficult to treat the industrial wastewater. Polyacrylamide for printing and dyeing sewage treatment produced by novel polymer can make the impurities in printing and dyeing sewage condense the group quickly, and the sewage can be restored and clarified after settlement and other treatment.

Which polyacrylamide used for printing and dyeing sewage treatment:

TIANDELI are polyacrylamide manufacturers, and they are produced as anionic, cationic, and nonionic. Anionic polyacrylamide ranged with molecular weights of between 400w and 2500w and cationic polyacrylamide ionicity of between 10% and 70%. Because the water quality of printing and dyeing sewage changes greatly, in the use of polyacrylamide specifications selection, we will generally determine which polyacrylamide to use through the sewage water sample test, which can not only guarantee the effect of printing and dyeing sewage treatment, but also can reduce the amount of polyacrylamide to save the cost of sewage treatment. If you do not know which specification of sewage treatment agent to use, you can directly contact us novel polypolymer, we help you test water samples and develop a suitable sewage treatment agent use plan.

Use of polyacrylamide for printing and dyeing sewage treatmea18f57a4bfa767fa8087a062a4c333d1nt precautions:

1. Polyacrylamide should be dissolved before use, and room temperature clarification water should be used. If the temperature is too high or excessive impurities in the water will lead to early degradation of polyacrylamide, which will affect the effect of sewage treatment.

. Polyacrylamide aqueous solution should not be stored for too long, for a long time shelved will also make the effect of sewage treatment becomes worse, so generally we all use now for water dissolution.

3. In Polyacrylamide, iron containers should not be used when dissolving the polyacrylamide in water and preserving the aqueous polyacrylamide solution. Plastic, ceramics, aluminum products and other containers should be used.

4. The Polyacrylamide water solution needs to be fully evenly mixed with the sewage when added, so that the effect of the sewage treatment will be better.
