  • What is polyacrylamide used for?
  • Polyacrylamide and its co-polymers are used as flocculants or coagulants in industrial wastewater treatment .Homo-polymer is used in this application and can be either nonionic, cationic or anionic depending on the types of wastewater needs to be treated. Also polyacrylamide can be prepared either as linear or as cross-linked.
  • Which polyacrylamide polymers were tested with distilled water?
  • In the first phase of experiments, seven polyacrylamide polymers (Hydrex 3591, 3593, 3596, 3661, 3572, MagnaFloc LT 27AG and FloPolymer CB 4350) were tested with distilled water to establish their detection limits and characteristics of their UV absorbance spectra.
  • What is the optimum dosage for a polymer jar test?
  • The optimum dosage for both tests was found to be 30 g/t for M 351 and 20 g/t for M 155, M 5250, and SPP 355 polymers. All polymers performed well in terms of turbidity during the jar test, while poor flocculation was observed in the graduated cylinder test due to insufficient mixing and polymer adsorption.
  • Which polymers perform well in a jar test?
  • All polymers performed well in terms of turbidity during the jar test, while poor flocculation was observed in the graduated cylinder test due to insufficient mixing and polymer adsorption. The M 5250 in the jar test and the M 155 in the cylinder test achieved the highest settling rates.
