Selection of flocculants
Thread Content
In the filtration process for phosphate production, flocculants are generally used to improve the filtering efficiency. Could you please share whether anionic or cationic flocculants are chosen?
Polyacrylamide flocculants are generally used. Polyacrylamide (PAM) is a water-soluble polymer that is insoluble in most organic solvents; it possesses excellent flocculating properties and can reduce the frictional resistance between liquids. Based on their ionic characteristics, they can be classified into four types: non-ionic, anionic, cationic, and amphoteric. Usage and precautions for PAM Polyacrylamide: 1. Determine the optimal type through pilot tests, as well as the best dosage of this product. 2. The product is prepared as an aqueous solution at a concentration of 0.1% (based on the solid content), with salt-free neutral water being preferred. 3. When dissolving in water, evenly sprinkle this product into the stirred water and apply appropriate heating (
