Practical Guide to PAM Dosage Techniques!

Polyacrylamide (PAM) is a water-soluble polymer that is insoluble in most organic solvents. It possesses excellent flocculating properties and can reduce friction resistance between liquids. Classified by ionic characteristics, it is categorised into three types: non-ionic, anionic, and cationic. Applications of Polyacrylamide 1) As a retention aid and strengthener in papermaking processes. 2) As a flocculant, coagulant and sludge dewatering agent in water treatment. 3) As a water reducer and oil displacement agent in petroleum drilling and extraction. 4) PAM is also extensively used for thickening, stabilising colloids, reducing drag, bonding, film formation, and in biomedical materials. Methods and Precautions for Polyacrylamide Dosage 1) Through pilot testing, determine the optimal product grade and its most effective dosage. 2) Prepare the product as a 0.1% aqueous solution (based on solid content), preferably using neutral, salt-free water. 3) When dissolving in water, evenly disperse the product into agitated water. Moderate heating (<60°c) may accelerate dissolution. 4) Solid products are packaged in polypropylene woven sacks lined with plastic bags, each containing 25kg. Gel formulations are supplied in plastic drums lined with plastic bags, available in 50kg or 200kg capacities. 5) This product is hygroscopic and should be stored in a sealed container in a cool, dry place at temperatures below 35°C. 6) Avoid spilling solid product on the floor to prevent moisture absorption causing slippery surfaces. 7) Prepare PAM aqueous solutions in enamel, galvanised, aluminium, or plastic containers. Do not prepare or store in iron vessels. 8) During dissolution, add the product slowly and evenly into a dissolver equipped with stirring and heating capabilities. Avoid clumping. Prepare the solution at an appropriate temperature and avoid prolonged, excessive mechanical shear. Stirring speeds of 60–200 rpm are recommended; otherwise, polymer degradation may occur, affecting performance. 9) PAM aqueous solutions should be prepared immediately prior to use. Prolonged storage of dissolved solutions will result in gradual performance degradation, depending on water quality. 10) Following the addition of flocculant solution to a suspension, prolonged vigorous agitation will disrupt the formed flocs.
