  • Why should we use Pam instead of inorganic flocculant?
  • In treatment, using organic flocculant PAM instead of inorganic flocculant, the water purification capacity can be increased by more than 20% even if the sedimentation tank is not reformed. So at present, many large and medium-sized cities in the water supply shortage or poor water quality, are using PAM as a supplement.
  • Is Pac-am-DMC a novel organic-inorganic hybrid flocculant?
  • The poly aluminium chloride-acrylamide-methacryloxyethyltrimethyl ammonium chloride (PAC-AM-DMC) flocculant was found to be a novel organic-inorganic hybrid flocculant in this study due to having a good yield at low applied dosage; therefore, leaving less chemical residue in waters after flocculation.
  • What are inorganic polymer flocculants?
  • 4.2.1 Inorganic polymer flocculants. Aluminum salts and iron salts have been widely used as inorganic flocculants in water and wastewater treatment. The main products are aluminum sulfate, ferrous sulfate, iron sulfate, polyaluminum chloride (PAC) and PFS.
  • What are synthetic chemical coagulants?
  • Synthetic chemical coagulants are based on organic polymers (or polyelectrolytes) while the natural-based organic coagulant is derived from both plants and animals. In water and wastewater treatment operations, organic polyelectrolytes are used either for the CF operation or for sludge dewatering.
