  • How much cationic polyacrylamide should be used for sludge treatment?
  • For sludge treatments, consumption of a cationic polyacrylamide of 5.4 g·kg −1 of total solids is found to be the best economical solution . Several studies were made, following life cycle analyses, to evaluate energy consumption of wastewater treatment (e.g., Tillman et al. , Hospido et al. and Wenzel et al. ).
  • Where are polyacrylamides used in New Zealand?
  • 1.6.3 Most polyacrylamides used in New Zealand for drinking-water treatment are manufactured in the USA, Europe and Australia. Polyacrylamides are normally dosed directly to water from a mixing or day tank via a positive displacement metering pump.
  • Is acrylamide cationic or nonionic?
  • Polyacrylamides can either be nonionic, anionic, or cationic. The nonionic polymer is made solely from acrylamide monomer, while the anionic form also uses an acrylic acid monomer, and the cationic form also uses a cationic acrylamide based salt monomer (eg, ethanaminium, N,N,N-trimethy1-2-[(1 -oxo-2-propenyl)oxy]-, chloride).
  • Do polyacrylamide suppliers comply with health and safety requirements?
  • Suppliers of polyacrylamides shall comply with the requirements of the Health and Safety in Employment Act 1992, and the Transport Act 1962. All practicable steps must be taken to protect the purchaser and others in the environment from hazards arising from the transportation, delivery and supply of polyacrylamides.
