  • Can printing and dyeing wastewater be treated?
  • In this study, printing and dyeing wastewater treatment technologies were examined. This wastewater contains a high concentration of dyes, salts, and other contaminants. Physicochemical processes have several limitations to treat the wastewater. Adsorption technology can result in dye rejection rates of over 90%.
  • What is printing and dye wastewater (PDW)?
  • Printing and dye wastewater (PDW) is the aqueous effluent released by factories that operate the dyeing and finishing of wool and silk, among other things. Dyeing and finishing activities in the textile industry account for up to 20 % of all wastewater discharged globally .
  • What technologies are used to treat printing and dyeing wastewater?
  • The printing and dyeing wastewater (PDW) contains a high concentration of dyes, salts, and other contaminants. This study is a review of published literature that utilised various technologies for the treatment of PDW. The studied technologies include adsorption, membrane technology, advanced oxidation processes, and biological processes.
  • Are papermaking sludge-based flocculants effective in dyeing wastewater treatment?
  • In our previous studies, several papermaking sludge-based flocculants (PSBFs) were synthesized from wood pulp papermaking sludge. The structure-activity relationships of the PSBFs have been investigated in simulated dye wastewater treatment, but their efficiencies in practical printing and dyeing wastewater (PPDW) treatment are unknown.
