Polyacrylamide zwitterionic PAM is suitable for the treatment of wastewater with uncertain properties of suspended solids and pH value. If a desilting tank or sewage is used, as long as the temperature is not lower than ice, PAM will use low temperature in winter without any harm. Due to the decrease of water temperature and the increase of water viscosity, ionic PAM is slightly slower than the inclined plate sedimentation tank of non-positive ionic PAM.

   Polyacrylamide has no toxic and side effects, but there is still n-butyric acid remaining in the process of confluence, so pay attention when using it! In the liquid phase adsorption, the water treatment agent particle pam is often used, and the air is generally adsorbed in layers. The adsorption layer can be divided into three categories according to its adsorption layer: fixed layer, moving layer and flowing layer.

       The concentration value can be reduced until the concentration value disappears through the difference in the concentration value of internal positive ions, functional groups and chemical components in the solution, as well as the fusion force between the polymer electrolyte solution and water. And the control of the humectant to achieve a relatively satisfactory water absorption is the elasticity of the vulcanized rubber. The higher the degree of chemical crosslinking of the molecular formula, the stronger the elasticity of the vulcanized rubber. The balance between the elasticity and water absorption of the vulcanized rubber lies in its apparent water absorption.

      PAM can solve the production wastewater in all industries: such as printing and dyeing wastewater, leather product wastewater, fluorine-containing wastewater, heavy metal wastewater, oil-containing wastewater, papermaking wastewater, coal preparation wastewater, mining wastewater, brewing wastewater, metallurgical industry wastewater, meat food wastewater , wastewater treatment, glue treatment in paper industry, special sugar solution, forging molding, anti-wrinkle fabric, metal catalyst, special medicine, concrete quick-setting, cosmetic and other industrial fields.

      PAM has a certain salt tolerance, which other tackifiers cannot achieve. Under normal circumstances, adding polyacrylamide adhesive to water will slowly dissolve after five minutes, and will dissolve after half an hour, and it is not easy to form components in water. Polyacrylamide can fully activate its thickening effect after several hours.

      The cationic degree of cationic polyacrylamide is about 3%. Because of its various active and lovely functional groups, it can be adsorbed in large quantities to form covalent bonds. This product is mainly a negatively charged colloidal solution in the inclined plate sedimentation tank, which has the functions of removing turbidity, decolorization, adsorption and adhesion. It is used for wastewater with high content of organic solvents in coloring, papermaking, food, engineering construction, metallurgy, mineral processing, pulverized coal, oil and gas fields, aquatic product processing, alcoholization and other industries.

     So, does the temperature have any effect on the solubility of PAM? When the temperature does not drop to 0 °C, the dynamic viscosity of water will weaken the Brown movement of particles in the water, as well as the fitness movement and collision opportunities of particles in the water. Therefore, a slightly lower temperature will increase the difficulty coefficient of sewage treatment. Only by fully grasping the low temperature of sewage, it will be very simple after thawing. You can choose a coagulant according to the characteristics of the water, invest in lower sewage to remove the particles of the colloidal solution, and then choose a flocculant of specifications to make it achieve good practical results.
