  • 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. ).
  • What are the different types of cationic polyacrylamide synthesis technologies?
  • There are four main kinds of cationic polyacrylamide synthesis technologies: in aqueous solution, in dispersion, by inverse emulsion, or through photoinitiated polymerization . These methods had experienced numerous developments and modifications such as free radical copolymerization or grafting processes .
  • What is cationic polyacrylamide (CPAM) emulsifier?
  • Authors to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) emulsifier is widely applied in the wastewater treatment industry, mining industry, paper industry, cosmetic chemistry, etc.
  • How is cationic polyacrylamide obtained?
  • In the photoinitated polymerization method (Fig. 4), the cationic polyacrylamide is obtained by photoactivation of monomer solution. This synthesis technique is characterized by many advantages: operation simplicity, easy control, low cost, and obtained product has high purity [11, 12].
