Polyacrylamide

Polyacrylamide is inorganic polymer flocculant polymer, all walks of life sewage treatment polyacrylamide basically have a good application. However, polyacrylamide compared with general flocculation products, the price is high, and the operation and use need special attention, so the use of polyacrylamide is very important. The correct operation method can not only exert the benefit of the drug, but also reduce the operating cost of the treatment. Three Tuo water purification for everyone to do polyacrylamide use method guide, there are the following points:

1. The appearance of polyacrylamide is white solid uniform particles. It is an inorganic polymer, divided into cationic polyacrylamide, anionic polyacrylamide and non-ionic polyacrylamide according to ionic type.

2. Polyacrylamide is easily soluble in water, but the dissolution rate is slow. When operating, it is recommended that the stirring time is 40 minutes, which can effectively play the effect of solid polyacrylamide.

3. When polyacrylamide treatment sewage acts as a flocculant, it is recommended to use 1-5g per ton of sewage. The actual dosage, it is recommended to do a small beaker test in advance.

4. The polyacrylamide solid should be diluted before use, and the dissolution ratio is recommended to be 1/1000 or 3/1000, and the concentration is too high to cause blockage.

5. Under normal circumstances, anionic polyacrylamide and non-ionic polyacrylamide as flocculants have good effect and are used more.

6. Cationic polyacrylamide is generally used in mud dewatering or sludge dewatering.

7. After the dilution and dissolution of polyacrylamide, it is recommended that the polyacrylamide solution be used within 24-36 hours. Storage time is too long, the effect is reduced.

8. It should be noted that cationic and anionic polyacrylamide cannot be doped, which will cause polyacrylamide to lose its efficacy.

9. It should be noted that when the polyacrylamide is diluted and stirred, the mixing should not be too intense. It is easy to cause molecular weight fracture, and the treatment effect is not good.
