As a well-known polymer flocculation reagent, polyacrylamide is often used as a water treatment reagent in different waters. However, some customers report that polyacrylamide cannot meet his needs. In fact, it has a lot to do with the way of use. In this regard, in order to not only meet the needs of customers, but also improve the efficiency of use, the polyacrylamide manufacturer tells you the specific improvement methods as follows:
1. It has a direct relationship with water temperature. According to experiments, the water temperature for dissolving polyacrylamide is 20°C and 30°C. When the temperature increased by 10°C, the hydrolysis rate doubled. Temperature has a great influence on the flocculation effect of aluminum salt. When the water temperature is lower than 5°C, the hydrolysis rate of the aluminum salt is very slow, and the hydrolysis effect is obviously reduced. This shows that we must pay attention to the water temperature problem.
2. Add coagulant aids appropriately. Sometimes, when the polyacrylamide flocculant alone cannot achieve good results, some kind of coagulant can be added to assist the adjustment, improve the flocculation conditions, and improve the treatment effect. Therefore, it is necessary to add a coagulant in combination with polyacrylamide at a specific time.
3. The mixing time of polyacrylamide should be increased. To dissolve polyacrylamide well, then use it to enhance the use of polyacrylamide.
In short, in order to achieve the use efficiency of polyacrylamide, in addition to ensuring the quality of polyacrylamide purchase, it must be operated strictly in accordance with the prescribed use methods, so as to avoid waste and effectively improve the water purification efficiency and quality of the product. .
