  • What are the major wastewater producers in the pulp-and-paper industry?
  • Wood preparation, pulp washing, pulp bleaching and paper making processes as well as the digester house are the major wastewater producers in the pulp-and-paper industry. The volume of wastewater produced in each process is closely related to the quantity of generated pulp in that particular process (The World Bank Group, 1999).
  • Can UASB be used in pulp-and-paper wastewater treatment?
  • The established application of UASB process in the treatment of pulp-and-paper wastewaters has enhanced the use of a variety of anaerobic technologies including PBRs and FBRs (Table 4). These processes offer higher removal efficiencies for AOX and lignin.
  • Which wastewater treatment techniques are used in pulp-and-paper industry?
  • Wastewater treatment techniques used in pulp-and-paper industry are reviewed. Numerical models are developed to estimate GHG emissions for each technique. Contaminant removal efficiencies and GHG emissions depend on operating parameters. Hybrid process is found to be the most appropriate and stable treatment technique.
  • Why is wastewater treatment important in pulp-and-paper industry?
  • The treatment of the generated wastewater in pulp-and-paper industry serves to remove contaminants, conforming to environmental regulations, while offering the possibility of using the treated effluent as the process water in the production mills, if its quality permits.
