Amphoteric polyacrylamide contains cationic and anionic groups in its molecule. It possesses the characteristics of common cationic flocculants and exhibits more excellent properties. Such flocculants can be used in a wide range of PH values, with higher water filtration capacity, lower cake moisture content, and can also be used for strong acid leaching of ores or recovering valuable metals from acidic catalysts containing metals. Amphoteric polyacrylamide is by no means a mixture of anionic and cationic polyacrylamide.
Polyacrylamide emulsions are used in wastewater treatment, such as water flocculation and sedimentation, sludge dewatering and filtration, construction slurry treatment, petroleum industry, mineral production sewage treatment, and alumina wastewater disposal and treatment.
Municipal sewage is the general name of domestic sewage, industrial wastewater and runoff sewage in the urban area. It is usually collected and discharged into water bodies by
Polyacrylamide is a kind of polymer compound which is commonly used as flocculant and precipitant in industrial wastewater treatment. Industrial sewage contains a lot of suspended solids and dissolved organic matter, which will cause serious pollution and ecological damage to the water environment. Therefore, effective treatment of industrial sewage is essential to protect the water environment and ecosystem.
Cationic Polyacrylamide (CPAM) is formed by copolymerization of cationic monomer and acrylamide monomer. It is a water-soluble linear polymeric flocculant. It is mainly used in flocculation and sedimentation of sewage and sludge dewatering and so on.
