Polyacrylamide - an overview | ScienceDirect Topics

Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the capture of dispersed bacterial cells, suspended solids, and cell fragments; therefore, one of its

However, over treatment is still possible since good flocculation does not occur if more than 50% of the particle surface is covered by polymer. Anionic polymer frequently give the best bridging action because their polymer chains are more uncoiled and therefore exposed to a greater number of separate particles when added to the water.

Cysticercosis is usually acquired by eating food or drinking water contaminated by tapeworm eggs from human feces. Among foods, uncooked vegetables are the major source. The tapeworm eggs are present in the feces of a person infected with the adult worms, a condition known as taeniasis. Taeniasis, in the strict sense, is a different disease and is due to eating cysts in poorly cooked pork.
