The effect of cationic polyacrylamide in sludge dewatering is very good, how to make the effect of cationic polyacrylamide in sludge dewatering better, what we need to pay attention to in sludge dewatering? Lvyuan Environment Group Co.,Limited to explain the knowledge of cationic polyacrylamide.
An important factor of cationic polyacrylamide in sludge dewatering is temperature. When the temperature of polyacrylamide drops to about 2 ℃, it begins to greatly reduce the effect of flocculation. When the temperature is lower than zero ℃, it basically has no effect. Generally, the effect of polyacrylamide is very good at about 25 degrees, so it is very important to ensure the use of polyacrylamide at room temperature.
Cationic polyacrylamide in sludge dewatering, can not be in the strong acid or alkali environment, otherwise it will lose effect. Under normal conditions, the pH value of polyacrylamide should be between 6-8.
When cationic polyacrylamide is used in sludge dewatering, inorganic flocculants, such as polyaluminum chloride and polyferric sulfate, are needed. The use of polyacrylamide not only has a good flocculation effect, but also greatly improves the effect of inorganic flocculation, which makes the sludge dewatering efficiency higher and the sludge dewatering rate better.
The polyacrylamide produced by Lvyuan Environment Group Co.,Limited has high quality and good effect. The company has an excellent technical team, which can make a reasonable and effective use plan after customers purchase polyacrylamide, strive to achieve the ideal use effect with less usage, save costs for customers, so as to achieve a win-win and mutually beneficial long-term cooperation relationship with customers.
