What are The Differences between Polyacrylamide and Polyaluminum Chloride
May 07, 2024
In the process of sewage treatment, there are times when polymerized aluminum chloride is used, and there are times when polyacrylamide is used, since both are Water Treatment Chemicals with sewage treatment effects. Why are there two different types? The two certainly have different uses of the existence of Polyacrylamide and Polyaluminum Chloride in the use of what is the difference?
Polyaluminum Chloride is an inorganic flocculant, the effect of sewage treatment is also good, it is used in a wide range of scale, widely used to a variety of water. It can form large alum flowers quickly, and has good deposition performance. The scale of suitable PH value is wide, and the PH value and alkalinity of water after treatment are small. When the water temperature is low, it can still keep stable deposition effect. Alkalinity is higher than other aluminum salt and iron salt, and the erosion effect on equipment is small.
Polyacrylamide is an organic flocculant, also known as PAM, polyacrylamide is mainly used in sewage treatment, raw water treatment and industrial water treatment. In sewage treatment. Polyacrylamide can be used for sludge dewatering; in raw water treatment, polyacrylamide and activated carbon, etc. with the application, can be used for the coagulation and clarification of suspended particles in daily water; in industrial water treatment, the primary use as a formulation agent. In sewage treatment, the use of PAM can increase the utilization rate of water reuse cycle. In the raw water treatment, organic flocculant PAM instead of inorganic flocculant, in the case of not transforming the settling tank, can also increase the capacity of 20% of the clear water. Now many large and medium-sized cities have a serious water supply or poor water quality, by PAM to make up.
