  • 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.
  • Which flocculant is best for pulp & paper mill wastewater treatment?
  • Organopol 5415 with very high molecular weight and low charge density is the best flocculant with highest flocculation efficiency for the treatment of the pulp and paper mill wastewater. It can achieve 95% of turbidity reduction, 98% of TSS removal, 93% of COD reduction and SVI of 14 ml g −1 at the optimum dosage of 5 mg l −1.
  • Can polyacrylamide be used alone in coagulation-flocculation process?
  • Based on the cost evaluation, the use of the polyacrylamides is economically feasible to treat the pulp and paper mill wastewaters. This result suggests that single-polymer system can be used alone in the coagulation-flocculation process due to the efficiency of the polyacrylamide.
  • Can UD and RSM be used for tertiary treatment of pulp and paper mill wastewater?
  • Confirmation experiments by the combination of the UD and RSM. for tertiary treatment of pulp and paper mill wastewater was studied by Dewi et al. (2011). They investigated the wastewater. laboratory scale aerobic stabilization basins (ASB). They studied two samples of post coagulated wastewaters.
