  • Can alum and PACL be used as coagulants in paper-recycling wastewater?
  • In the present study, a coagulation process was used to treat paper-recycling wastewater with alum coupled with poly aluminum chloride (PACl) as coagulants. The effect of each four factors, viz. the dosages of alum and PACl, pH and chemical oxygen demand (COD), on the treatment efficiency was investigated.
  • Can alum coagulants reduce turbidity in pulp and paper mill wastewater?
  • The treatment of pulp and paper mill wastewater using alum coupled with PACl as coagulants enhanced the reduction removal of turbidity and COD and produced a lower volume of sludge compared to the results obtained when the coagulants were used alone.
  • 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.
  • Can wastewater recirculation be used in pulp & paper industry?
  • These technologies are widely used for treating industrial wastewater (chemical, food, dairy and textile) and municipal wastewater but not in the pulp and paper industry ( Shamsuddin et al., 2015 ). UF is considered the best candidate for the recirculation of water in papermaking ( Su et al., 2016 ).
