  • How does the pulp & paper industry use water?
  • The pulp and paper industry consumes enormous amounts of water and natural resources and is also one of the largest effluents generators. Before the 1970s, wastewaters from the pulp and paper mills were normally discharged directly to the rivers or lakes, without any treatment or even a rough primary treatment.
  • Does the pulp and paper industry treat wastewater and reclamation?
  • "Wastewater treatment and reclamation: A review of pulp and paper industry practices and opportunities," BioRes. 11 (3), 7953-8091. The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters.
  • Is pulp and paper industry polluting water?
  • From the journal Physical Sciences Reviews Pulp and paper industry is coming under one of the most water polluting industries, and generated wastewater is highly toxic in nature.
  • What percentage of pulping plants use biological effluent treatment systems?
  • Sixty to seventy-five per cent of all the biological effluent treatment plants within the pulp and paper industry use this kind of treatment system. This chapter reviews the current pulping technologies at mills and compares the chemical composition and biological treatment of wastewater between softwood and hardwood bleached pulps. 1.
