Urban Domestic Sewage Treatment Polyacrylamide Polyacrylamide and sewage treatment flocculants are more important in urban domestic sewage treatment solutions. Domestic sewage treatment has always been a difficult problem. In the past, septic tank sedimentation and anaerobic fermentation were commonly used, although they have certain effects on suspended matter and parasite eggs. It has a certain …
What Is the Impact of the Ionicity of Cationic Polyacrylamide? What is the impact of the ionicity of cationic polyacrylamide? The ionicity of cationic polyacrylamide is the charge density of polyacrylamide itself. It is a relative concept. The higher the charge density, the higher the ionicity. The ionicity determines the molecular chain length and price …

Application of Polyacrylamide in Paper Industry The application of polyacrylamide in the papermaking industry. As a flocculant, polyacrylamide can promote the accumulation of suspended solids, colloids and other substances in sewage to form flocs for subsequent filtration, sedimentation and other treatment processes. In order to improve the strength of paper and save papermaking raw materials …
Anionic Polyacrylamide Anionic polyacrylamide promotes particle flocculation by neutralizing the charges on the surface of suspended particles in water, thereby destabilizing the particles in the water. The destabilized particles adsorb each other under the bridging effect of the active genes of the polymer polymer, and then form larger of clumps. How to use anionic polyacrylamide …
Treatment of the Problem of Viscosity Decrease of Polyacrylamide Solution To deal with the problem of decreased viscosity of polyacrylamide solution, after polyacrylamide is prepared into a solution, if it is not used in time, the viscosity will decrease when it is used again after a period of time. So what is the reason for …

Selection Method of Cationic Polyacrylamide 1. Sampling sludge samples to be pressed: Select representative sludge samples and take samples before the on-site dosing point. After taking the samples, the experiment should be carried out as soon as possible (the properties of the sludge may change after being left for a period of time). Polyacrylamide samples: …
How to Choose Polyacrylamide Models for Different Sewage Treatment Processes How to choose the polyacrylamide model for different sewage treatment processes. The sewage treatment process can be divided into two processes: sewage desliming and sewage flocculation. The polyacrylamide models used in different processes may be different, so how to choose? Anionic polyacrylamide is generally used …
