  • How are pulp and paper mill wastewater treated?
  • Some researchers treated pulp and paper mill wastewater by the electrochemical degradation method followed by coagulation/flocculation, ozone treatment, and biological methods for COD and color removal but mostly not deal with reuse of the resources.
  • What are the treatment systems used in pulp & paper industry?
  • Therefore, the pulp and paper industries have several treatment systems, such as anaerobic treatment, activated sludge lagoon, clarifier system for remove organics, and inorganic substances from the wastewater and to meet the effluent discharge standards. The use of inorganic salts for coagulation–flocculation has been well documented.
  • What is a conventional wastewater treatment system in pulp & paper industry?
  • Though, the conventional wastewater treatment systems widely practiced in pulp and paper industry generally involve primary clarification followed by activated sludge processes.
  • What are the treatment processes for pulp and paper industrial effluents?
  • Various treatment processes for pulp and paper industrial effluents, including aerobic, anaerobic, photo-catalysis, electrochemical, ozonation, coagulation–flocculation and adsorption treatment processes have been presented.
