  • 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).
  • Why is wastewater treatment important in pulp & paper industry?
  • The treatment of the generated wastewater in pulp-and-paper industry serves to remove contaminants, conforming to environ-mental regulations, while offering the possibility of using the treated ef uent as the process water in the production mills, if its fl quality permits.
  • 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.
  • How is paper-making wastewater treated?
  • Mansour et al. (2007) treated paper-making wastewater using coagulation and electroflotation to remove color, suspended solids, and COD. They used batch and continuous processes for wastewater treatment, and showed that both processes were capable of removing color and suspended solids and producing a clear effluent.
