  • Can polyacrylamide be used to treat pulp and paper mill wastewater?
  • SVI values of less than 70 m lg (-1) are found for all polyacrylamide at their respective optimum dosage. Based on the cost evaluation, the use of the polyacrylamides is economically feasible to treat the pulp and paper mill wastewaters.
  • Can coagulation flocculation be used to treat pulp and paper mill wastewater?
  • A study using coagulation–flocculation method for the treatment of pulp and paper mill wastewater has been carried out. The efficiency of alum and polyaluminum chloride (PACl) when used alone and in coupled with cationic polyacrylamide (C-PAM) and anionic polyacrylamide (A-PAM) on the treatment of pulp and paper mill wastewater were studied.
  • How much water does the pulp and paper industry consume?
  • The pulp and paper industry is a very water-intensive industry and can consume as high as 60 m 3 of freshwater per tonne of paper produced . The generation of wastewater and the characteristics of pulp and paper mill effluent depend upon the type of manufacturing process adopted.
  • Does alum coagulant reduce turbidity in pulp and paper mill wastewater?
  • 4. Conclusions The treatment of pulp and paper mill wastewater using alum and PACl coagulant in coupled with PAMs enhances the reduction/removal of turbidity, TSS and COD, improves the flocs settling time and produces lower volume of sludge compared to the results obtained when the coagulants are used alone.
