The effect of cationic polyacrylamide in sludge dewatering is very good, how to make the effect of cationic polyacrylamide in sludge dewatering better, what things we need to pay attention to in sludge dewatering?


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.


From the perspective of customers, the company produces polyacrylamide with high quality and good effect. We have excellent technical team, can make a reasonable and effective use plan after customers buy polyacrylamide, strive to achieve the ideal use effect with less usage, save cost, so as to achieve a win-win and mutually beneficial long-term cooperative relationship with customers.
