Main application 1)PAMC is very effective in sludge dehydration. Different types of PAMC are available according to the condition of sludge. Most of water can be filtrated before press filtration. Because PAMC effected floccules are big, filtration cake can be thick and the water remaining is <80%. 2)PAMC is suitable for the treatment of organic substances enriched waste water. PAMC is cationic in acid or basic medium, making it an ideal clarifier for waste water with anionic granules. It can be widely used in waste water treatment in alcohol making, papermaking, brewery or beverage making, sugar making, dyehouse, textile industry, domestic sewage, etc. These kinds of water is always anionic charged, so PAMC is more effective than PAMA, PAMN or inorganic salts. 3)PAMC is a cost-effctive flocculant of river water in tap water treatment, especially when combined with inorganic flocculants. It is suitable for water from the main rivers in China. 4)As strengthening agent or other auxiliary agents in paper industry. 5)As antiexpanding agent for clay or thickening agent on acidification in oil drilling.
