  • 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.
  • Can aluminum sulfate be used to treat papermaking white water?
  • " Application of aluminum sulfate in the treatment of papermaking white water ," BioResources 16 (1), 1382-1393. Physical chemical methods were used to treat papermaking white water used to produce plant fiber mulch sheet that contained fine fibers and inorganic fillers as suspended solids.
  • What is the water quality index of papermaking white water?
  • The water sample used for the water quality index of the papermaking white water was taken from a paper mill in the Heilongjiang province of China that produced plant fiber mulch sheet. The pH of white water was between 7.5 and 7.8, the chemical oxygen demand (COD Cr) was 640 to 872 mg/L, and the suspended solid was 160 to 193 mg/L.
