preparation, performances, and mechanisms of microbial,polyacrylamide is the most commonly used in the synthetic organic flocculants . although the polyacrylamide itself has no toxicity, its difficult degradation easily cause secondary pollution, and the residue of polymer monomer acrylamide is also a very worrying problem, as it not only has a strong neurotoxicity, but also a strong carcinogen [ 14 ].

degradation of polyacrylamide and its significance in nature

the hydrolyzed form of polyacrylamide (hpam), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic pam in oil and gas development as well as in soil conditioning.

research on a new cationic polyacrylamide (cpam) with high quality,flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (srf), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge. therefore, it is particularly important to develop new and efficient flocculants

  • What are cationic polyacrylamide copolymers?
  • Cationic polyacrylamide copolymers (PAM) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).
  • Are cationic polyacrylamide copolymers harmful to the environment?
  • Cationic polyacrylamide copolymers (PAM) are used for sludge dewatering in municipal wastewater treatment and may enter the environment through the spread of sludge on agricultural fields. There is concern about the degradation of PAM in soils because little is known.
  • What is polyacrylamide (PAM) used for?
  • High molecular weight polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction reducer in enhanced oil recovery and high-volume hydraulic fracturing.
