Polyacrylamide (PAM) is a water-soluble polymer, which is insoluble in most organic solvents, has good flocculating properties, can reduce frictional resistance between liquids, Can be divided into non-ionic, anionic, cationic and amphoteric four types.
When PAM is used for flocculation, it is related to the surface properties of the species being flocculated, especially the potential, viscosity, turbidity, and pH of the suspension. The kinetic potential of the particle surface is the reason for particle inhibition. Can reduce the potential and condense.
Granular polyacrylamide flocculant cannot be directly added to sewage. It must be dissolved in water before use, and its aqueous solution are used to treat sewage.The water in which the particulate polymer is dissolved should be clean. Generally tap water is suitable for formulating polymer solutions. Strong ACID, strong alkali, high salt water is not suitable for preparation. Water at room temperature is ok, no necessary to heat. Dissolution is slow when the water temperature is below 5 ° C. Increasing the water temperature will accelerate the dissolution rate, but above 40 ° C will accelerate the degradation of the polymer and affect the use effect. The solution concentration is recommended to be 0.1% -0.3%.
