Improvement of alum and PACl coagulation by polyacrylamides (PAMs) for the treatment of pulp and paper mill wastewater

Overall, alum coupled with Organopol 5415 is the best system among all systems studied. It gives 99.7% reduction of turbidity, 99.5% removal of TSS and 95.6% reduction of COD, and at the same time with low SVI (38 mL/g) and low settling time (12 Keywords Coagulation Flocculation Polyelectrolyte Sludge volume index 1.

PolyDADMAC and polyacrylamide as a hybrid flocculation system in the treatment of pulp and paper mills waste water

The flocculation performance of polydiallydimethylammonium chloride (polyDADMAC) coupled with polyacrylamide for treating pulp and paper mill wastewaters was studied. The flocculation performance tests were carried out in jars with polyDADMAC and polyacrylamide (PAM) dosages of 0.4¨C2.0 mg L ?1 and 0.4¨C8.0 mg L ?1 , respectively.

Treatment of pulp and paper mill wastewater by polyacrylamide (PAM) in polymer induced flocculation

Anionic polyacrylamide 1. Introduction 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 [1]. The generation of wastewater and the characteristics of pulp and paper mill effluent depend upon the type of manufacturing process adopted.
